What to Wear to Protect Your Eyes

Your eyes are among the most important organs in the body when it comes to discovering and interacting with the world around you. Unfortunately, they are also among the most exposed, and vulnerable to damage. That’s why it’s so important to ensure that proper protective gear is worn in places and situations where you might accidentally sustain an eye injury.

Whether it’s participating in sports, working with chemicals while cleaning or in a lab, or working on do-it-yourself projects around the home, it’s important to know what counts as proper protection, and what doesn’t.

Fortunately, our eye doctors at are here to explain.

Do Normal Prescription Glasses Count As Safety Equipment?

In short, no. Prescription glasses are built with materials that are primarily useful in promoting wearer comfort and helping you see better and more clearly.

The kinds of plastics and metals used in the frames are built for comfort, but may not hold up against flying shards of metal and wood.

Likewise, lens materials in prescription eyeglasses are chosen for their ability to be easily shaped and molded to give you optimum vision while minimizing aberrations. This ability to be easily molded does not lend itself well to also being impact-resistant.

Safety equipment gear for the eyes is also built with an extra guard around the sides to protect from flying debris and chemicals from all-around. This extra guard is not present in the vast majority of prescription eyeglasses.

So what IS considered proper safety equipment for protecting your eyes?

Personal Protective Equipment For Protecting Your Eyes

In general, there are three types of accepted safety equipment depending on your particular needs and preferences:

Safety Glasses

are made with shatter-resistant lenses, which are manufactured from materials like propionate plastic or polycarbonate. They also have side shields that help from debris and dust that may enter from the sides of, rather than in front of, the face.

What are safety glasses good for? These glasses are designed to be shatter-resistant and protect the eye from large, physical objects such as wood chips or metal or glass shards that could impact the eye, causing serious injury. Some types of safety glasses also offer laser light filtration, preventing reflections from the laser entering the eye, causing painful retinal burns.

What are safety glasses NOT good for? Safety glasses are not meant for protection from liquids or vapors.

Safety glasses can be purchased with or without prescription lenses and can also be ordered with bifocals.

Safety Goggles

These are another common type of personal protective equipment. They may be vented or non-vented.

Non-vented goggles are used as protection from mists, vapors, fumes, or other airborne hazards that require the eyes to be completely covered.

Vented goggles are meant to protect the eyes from liquid chemicals that pose no danger from vapor or mist. These also have a series of buttons embedded into the plastic that house something called a “baffle plate,” which allows air to pass through, but acts as a blockage so that liquid can’t get in.

Be aware that there are many types of goggles on the market, and some are not meant for certain kinds of work. Common, hardware-store goggles, for example, often have holes drilled into the plastic, which can let vapors and liquids into the mask, making them unfit for laboratory work.

Face Shields

These are actually not meant to be worn as the sole line of protection for your eyes. Rather, they are supplemental protection for the entire face, and goggles worn underneath the face shield block any vapor or liquid which may make it past.

How to Choose Eyeglass Frames For Your Features

You’re ready for new glasses. But how do you know which frames will best suit your features?

Some people take pictures of all the pairs they try on and send them to their friends, family or coworkers for feedback. But that’s time consuming and not particularly efficient.

Here’s a better way! Learn what frame features to look to suit the size and shape of your face, as well as your skin tone.

Below are a handful of tips that are sure to help select your frame.

What’s Your Face Shape?

The secret to finding your perfect frames is choosing a pair that best suits your face shape.

You see, our features vaguely resemble particular geometric shapes.

For example:

  • Heart-shaped faces have a narrow chin, a wide forehead and cheeks, and are sometimes topped off with a widow’s peak hairline
  • Round faces have full cheeks, a more rounded hairline and chin, and are similar in width and length
  • Oval faces are similar to round faces, except longer and thinner
  • Square faces have a strong jawline and forehead, and are roughly equal in width and length

So a pair of rectangular frames on a square face will further emphasize the squareness, but rounder glasses can help soften those angles. Rectangular frames are best suited for an oval or round face.

If you don’t already know your face shape, just look in the mirror, close one eye, and draw the outline of your face with a washable marker. The end result should resemble one of the above-mentioned shapes.

Size and Color Matter

Consider the size and color of the frames, along with their shape. They should be the right size for your face—not too big and not too small. This is true for both adults and children.

If you have a cool skin tone, colors to consider for your frames are blue, pink, blue-grey, silver, black, or rose-brown.

If you have warmer skin tones, frame colors like warm blue, off-white, fire-engine red, orange, copper, peach, copper or gold tend to look better.

Looking for Your Ideal Frames? We Can Help!

Q&A

Frequntly Asked Questions with Dr. David Yesnick

Q: How do I choose glasses that my child will actually wear?

  • A: When choosing frames for your child, the most important factor is to let them help in the selection process. When children are allowed to choose their glasses frames they will be much more likely to wear them.

Q: How often should I get a new pair of glasses?

  • A: Optometrists recommend updating to new glasses every one to three years as needed.
    If your prescription has changed, you should definitely get a new pair to prevent eye strain and increase comfort.

How To Prevent Your Lenses From Scratching

If you wear glasses, then you know what a nuisance a scratched lens can be. Scratched or chipped lenses can interfere with your vision, making glasses uncomfortable to wear. Here’s what we recommend to keep your lenses scratch-free.

How to Avoid Scratching Your Lenses

Use a Protective Case

Using a sturdy eyeglass case will prolong the life of your lenses. No matter what kind of glasses you wear — standard, sunglasses, bifocal — you’ll want to protect them.

Be sure to choose a hard case with a soft inner lining and always have one on hand, either in your purse, backpack, or car.

When placing the glasses in their case, make sure the lenses are facing downwards, as this can reduce the risk of them being scratched. Additionally, avoid putting anything else in the case along with the glasses, especially sharp or metal objects.

Choose Anti-Scratch Lenses

Although no lenses are completely scratch-proof, there are certain coatings that can be added to the front and back of your lenses to make them more scratch resistant. Many lenses already come with this option, but sometimes it’s an optional addition. Anti-scratch coatings are particularly helpful for children’s glasses.

Remove Your Glasses Carefully

Handle your glasses by the temples (arms) and not the rims. This way, your fingers avoid the frame and lens area altogether, reducing the chance of inadvertently scratching them. Additionally, holding them by the temples with both hands ensures a better grip, so you’ll be less likely to drop them.

Set Them Down Properly

Never put glasses down with the lenses facing downward, unless it’s into a lens case. If you need to put them down and don’t have a case, rest them with the temples open and upside down — glasses tend to be more stable in this position.

Avoid placing them in a place where they’ll be easily knocked over or splashed on, like near a sink. Setting them down in the same place consistently will also reduce your risk of losing them.

Use the Right Lens Cleaner

It’s all too common for people to wipe their glasses with their clothing or other abrasive material. Doing so can scratch the lenses, especially if they’re dry.

Always clean your lenses with a soft microfiber cloth and specialized lens cleaning solution, items your optometrist’s office can provide.

When to Visit Your Optometrist

Unfortunately, it’s impossible to completely prevent your lenses from ever becoming scratched over their lifetime. Once they are scratched, there is little that can be done to repair the lenses. Most of the time the lenses need to be replaced.

At Yesnick Vision Center, we offer a wide array of frames and lenses, so you’re sure to find a pair to suit your eyes and needs.

Frequently Asked Questions with DR. YESNICK

Q: Can you request lenses made from glass? Is glass still used for lenses?

  • A: Yes. Opticians still sometimes use glass for lenses. However, glass is not used very often because they aren’t as safe. If these glass lenses breaks, they can shatters into many pieces and can injure the eye. Glass lenses are much heavier than plastic lenses, so they can make your eyeglasses less comfortable to wear.

Q: Can a coating be added to eyeglasses to protect them from further scratches?

  • A: A protective coating can’t be added to a lens after it’s scratched. The coating is applied when the lens is manufactured and can’t be put on later.

How to Keep Your Glasses Looking Brand New

A new pair of stylish glasses can make you feel great about the way you look. But once those frames get bent or the lenses get scratched, you won’t feel as proud to show them off. Our Las Vegas eye doctor shares essential tips on how to maintain the sparkle of your new designer glasses.

Cleaning your eyeglasses:

  1. Clean your hands before attempting to clean your glasses.
  2. Rinse the frames and lenses under cool (never hot!) water to remove any heavy debris.
  3. Using a bit of dishwashing liquid on each lens, rub both sides of the lenses and the entire frame gently with your fingers or a special lens cloth.
  4. Rinse the glasses with cool water; take care to remove all soap traces.
  5. Shake your frames gently so the excess water drips off.
  6. Dry the lenses and frame with a clean, lint-free cloth. Don’t use any towels that have been washed with fabric softener, as the material can leave smears on the lenses.

What NOT to do when cleaning your eyeglasses lenses:

  • Don’t use the edge of your shirt, paper towels or tissues; they can scratch the lenses
  • Don’t use saliva or your breath instead of water
  • Don’t use household surface cleansers, they contain ingredients that can damage coating on frames and lenses
  • Don’t wear your glasses in the shower to clean them; steam, hot water and shampoos can all damage the lenses

How often should you clean your eyeglasses?

Our eye doctor recommends doing this process daily, or as needed. Cleaning your eyeglasses regularly will help extend the life of your frames and lenses. When a full step-by-step sink cleaning isn’t convenient or possible, use a spray cleaner or lens cloth, available at our Las Vegas optical store.

How To Prevent “Mask Fog” on Your Glasses

If you wear glasses and a face mask, you’ve probably struggled with “mask fog.” Your lenses get all misty, requiring you to wipe your eyewear throughout the day. Below are a few strategies to help you prevent your eyeglasses from fogging up when wearing a mask.

But First, Why Do Glasses Fog Up?

Quite simply, condensation forms whenever moist warm air hits a cool surface. Your specs fog up when the mask directs your warm breath upward instead of in front of you — which is great for preventing virus transmission but bad for anyone with less-than-stellar eyesight.

Is Your Mask Well Fitted?

The mask should fit securely over your nose. Ideally, you’ll want to wear a mask with a nose bridge or one that can be shaped or molded to your face. When the mask fits properly, hopefully most of your breath will go through it, not out the top or sides.

Use Your Glasses To Seal the Top of Your Mask

This method works best with large, thick eyewear frames. By pulling your mask up higher on your nose and placing the lower part of your eyeglasses on the mask, you can get a snug fit that blocks your warm breath from escaping upward toward your eyewear.

Tape Your Mask to Your Face

You can always use tape to secure your mask across the bridge of your nose and the top of your cheeks. Use easy-to-remove tape, including adhesive, medical, or athletic. Just be sure to stay away from duct tape.

Soap and Water Help Prevent Fogging

This trick is one that healthcare professionals regularly turn to. All you need for this hack is soapy water (dish soap works best) and a microfiber cloth. Stay away from soaps with lotions in them as they can leave a thick residue, making it even harder to see.

Simply rub both sides of your lenses with a drop of soap, then buff the lenses with a soft microfiber cloth. This effective trick helps prevent your lenses from fogging up as a transparent, thin film of soap acts as a barrier.

Anti-Fog Wipes and Sprays

Another option is to purchase wipes and sprays designed to tackle foggy lenses. Read the fine print, as certain anti-fog solutions may not work as well, or may even damage lenses with coatings that minimize glare and fingerprint smudges, for example.

6 Signs You May Need Glasses

Many people don’t realize they have a vision problem. Perhaps they’ve gone years without glasses and haven’t noticed the gradual change in their vision. Or they’ve noticed a change, but put off a visit to an eye doctor. Regardless of whether you’re experiencing problems, make an appointment with Dr. David Yesnick to maintain your eye health. 

 

There are many clues that your eyesight needs correcting, such as struggling to read up close, or having trouble seeing street signs, or barely deciphering faces while watching a film. If you’re still not sure you need glasses, consider these 6 questions. 

 

Are You Frequently Squinting and/or Experiencing Headaches? 

 

Unless it’s unusually bright, there’s no reason to be squinting if your vision is clear. Although squinting may briefly enhance your eyes’ ability to focus, if done for too long it can tax your  eyes and surrounding muscles, which can result in frequent headaches. 

 

If you have to squint while working on your computer or using digital devices, you may be experiencing not only headaches but also digital eye strain or computer vision syndrome. The cure is often a pair of computer glasses, or blue light glasses, which are designed to block out or filter blue light. This can reduce headaches and squinting when using your digital devices. 

 

Are You Struggling to See Up Close? 

 

If the texts on your phone or restaurant menu look blurry, you may be farsighted. While reading glasses are a great option for near tasks, you’ll need to take them off for other activities.  Consider getting progressive lenses, which change gradually from point to point on the lens, providing the exact lens power needed for seeing objects clearly at any distance. Progressive lenses help you comfortably see near, far, and in-between all day long. 

 

Do You Struggle to See Things at a Distance?  

 

If you’re having difficulty seeing objects at a distance, you may be myopic (nearsighted).  Myopia is the most common cause of impaired vision in children and young adults. Consider a pair of glasses with high-index lenses, which are thinner and lighter than other lenses, along with anti-reflective coating. 

 

Do You Have Blurred Vision at Night?  

 

Are objects or signs more blurry at night? Do you experience halos or glare around lights while driving at night? These may be symptoms of a vision issue, such as myopia — though they can also be attributed to more serious ocular conditions, such as cataracts and glaucoma. To know the cause, get your eyes properly evaluated by Dr. David Yesnick. 

 

If determined that it is indeed myopia, consider getting prescription glasses with anti-glare or anti-reflective (AR) coating, as they allow more light in and also cut down on glare. This can dramatically improve night vision and help you see more clearly when driving at night. 

 

Are You Experiencing Double Vision?

 

If you’ve been experiencing double vision, contact Dr. David Yesnick, who will get to the root of the problem and provide you with a diagnosis. Double vision may be due to crossed eyes (strabismus), or a corneal irregularity, such as keratoconus, or another medical condition.

 

If you are diagnosed with any of these, you’ll likely need a pair of glasses with a prism correction that helps correct alignment issues. Special lenses prevent you from seeing double by combining two images into a single one.

 

However, note that if you experience sudden double vision, it may be a medical emergency that should be checked by an eye doctor immediately.

 

Are You Losing Your Place or Using Your Finger When Reading? 

 

If you’re frequently losing your spot or skipping lines when reading, you may have a vision problem. This could be due to strabismus, lazy eye, or astigmatism. 

 

The Importance of Regular Eye Exams

 

If you’re experiencing any of the symptoms listed above, it is essential to have a highly qualified optometrist examine your eyes to assess your vision and check for any eye diseases — and to do so as soon as possible. This is the only way to determine whether you need glasses or if something else is causing the problem. 

 

Even if you’re not experiencing any symptoms, it’s important to routinely get your eyes checked. Many eye diseases can be effectively treated before you notice major problems, so regular eye exams are important to maintain eye health. Contact Yesnick Vision Center in Las Vegas to make an appointment with Dr. David Yesnick. The sooner you get your vision checked, the faster you’ll be able to see clearly and enjoy a higher quality of life. 

What’s the Best Way to Clean Your Eyeglasses?

Did you know that about 50% of all Americans wear corrective glasses? With eyeglasses being so popular, you might assume people would know how to take care of their optical lenses properly, right? Wrong! When surveyed, most eyeglasses wearers respond that they clean their lenses by exhaling onto them and wiping the fog off with their shirt.

Unfortunately, this all-too-common practice can actually damage your eyeglasses. Our experts at Yesnick Vision Center, with optical stores in Las Vegas, Spring Valley, Summerlin, , , Nevada, share the following tips on the best way to clean your glasses.

Eyesight is precious. So are your eyeglasses.

Everyone appreciates the value of clear vision and the importance of doing everything possible to keep your vision safe and healthy. If you think of your eyeglasses as an investment towards your sharp vision, you’ll treat them with the care they deserve.

In addition to purchasing frames for your prescription eyeglasses, you may have chosen to coat the lenses with anti-glare, UV protection, and anti-scratch features. While these coatings are generally durable, they aren’t 100% damage-proof. Cleaning your lenses improperly can cause minor scratches.

What’s the worst way to clean eyeglasses?

The following cleaning solutions or methods rank as the absolute worst ways to treat your eyeglasses, because they can strip the lenses of their coatings and leave fine marks that can create a visual haze.

  • Window/glass cleaner
  • Ammonia
  • Bleach
  • Vinegar or lemon juice
  • Toothpaste
  • Tissues or napkins
  • Paper towels
  • Exhaling onto the lenses
  • Your shirt

What are the best ways to clean eyeglasses?

Keeping your lenses clean and clear is an essential part of optimizing your vision! The best cleansers to use include water, rubbing alcohol, dishwashing liquid, microfiber cloth, and special optical wipes.

Once you’re armed with the right substances, follow these guidelines:

  1. Run your glasses under lukewarm water (NOT hot water).
  2. Using a small drop of dish soap on your fingertips, rub both sides of the lenses and nose pads gently.
  3. Rinse the eyeglasses with warm water and dry gently with a clean microfiber cloth. Because microfiber doesn’t leave lint behind, your lenses should be sparkling clean.
  4. Keep individually-wrapped optical wipes handy so you can clean your eyeglasses throughout the day, as needed. Alternatively, spritz glasses cleaner or even rubbing alcohol from a spray bottle onto the lenses and wipe with a microfiber cloth.

How to Disinfect Glasses to Help Prevent COVID-19

Coronavirus and Your Eyeglasses

Did you know that our glasses (this includes the lenses and the frame) can potentially transfer viruses, such as COVID-19, to our eyes, nose, and mouth? This is because viruses — as well as bacteria — are easily transferred from our surroundings to our hands and then from our hands to our glasses.

In fact, research has shown that coronavirus can remain on glass surfaces for as long as 9 days. If we’re not careful, we can easily touch our glasses then touch our eyes, nose, or mouth, thus continuing the contagion cycle.

The danger is even higher for people with presbyopia, age-related farsightedness that generally affects those aged 40 and above. Presbyopes who wear reading glasses tend to put them on and take them off several times throughout the day. What’s more worrisome is that this age group is at higher risk for more serious complications from COVID-19.

The good news is that disinfecting your glasses is easy! Let’s delve into ways you should and should not disinfect your lenses at home.

What NOT to Use to Cleanse Your Glasses

Many of us may have rubbing-alcohol at home, and although it may seem like a perfectly good idea to use it to disinfect your specs, we discourage you from doing so. It may be too harsh for your eyeglasses, especially if you have any special coatings on your lenses.

Other products you should stay away from include ammonia, bleach, or anything with high concentrations of acid, such as lemon juice or vinegar, which can damage lens coatings and some eyewear materials.

How to Safely Disinfect Your Glasses

Now that we’ve eliminated the substances and chemicals that should not be used on your lenses, let’s see what is safe to use to clean eyewear.

Dish Soap and Water

The absolute easiest and most efficient way to disinfect and clean your lenses is to use lukewarm water with a gentle dish soap. Massage the soap onto each lens, rinse, and dry using a microfiber cloth (not paper towels, as the fibers can easily scratch lenses). While you’re at it, don’t forget to include your frame’s nose pads and earpieces.

Lens Cleaning Wipes

Pre-moistened lens wipes are excellent for cleaning your glasses, as well as your phone, tablet and computer screen. They remove bacteria, dust, dirt and germs from your glasses and the formula restores shine to glass surfaces without leaving any streaks or residue. The durable material is tough enough to remove stains, while being gentle enough not to scratch your screens or lenses. Contact Yesnick Vision Center to find out how you can access these.

So, In Summary:

  • Do not use rubbing alcohol to disinfect your glasses.
  • Avoid using household cleaners or products with high concentrations of acid.
  • Clean your glasses with a gentle dish soap and lukewarm water, or lens wipes.
  • Dry your glasses with a microfiber cloth to prevent smudging and scratching.

Disinfecting your glasses shouldn’t be stressful or worrisome. Just follow the easy steps above to protect your lenses and your health.

On behalf of everyone at Yesnick Vision Center in Las Vegas, Nevada, we sincerely hope you and your loved ones stay healthy and safe during this uncertain time.

How to Read Your Eyeglasses Prescription

You just had an eye exam and your optometrist gave you a new vision prescription for eyeglasses. Problem is, you can’t make sense of it. There’s a bunch of unfamiliar acronyms and numbers. You know all those numbers relate to the lenses that you need to wear to see clearly, but what does each one mean?

The simple explanation is that those numbers refer to the lens powers you need to correct your eye’s refractive error – so you can enjoy crisp vision instead of the blurred vision you’ve had until now.

If it’s been a while since your last eye exam, contact one of our Yesnick Vision Center offices in Las Vegas, Spring Valley, Summerlin, , , and , Nevada, to book an appointment with our eye doctor. We want you to have a sharp view of the world, and we’ll check your visual acuity thoroughly to issue your up-to-date, precise vision prescription for eyeglasses.

A Breakdown of Your Eyeglasses Prescription

Let’s go through the significance of the letters and numbers on your prescription:

  • OS and OD: these are Latin abbreviations that stand for oculus sinister and oculus dextrus, respectively. (If your prescription also says OU, it refers to oculus uterque, for both eyes.)
  • Numbers: generally, the greater the number is away from zero, the worse your vision – and the more vision correction you need. That translates into a stronger prescription.The numbers represent diopters (sometimes abbreviated “D”), which is the standard unit for measuring the focusing power of the lens your eye requires to see clearly.
  • +/- : if there is a plus/+ sign before the number, it means you are farsighted; if there is a minus/- sign before the number, it means you are nearsighted.
  • S x C x AXIS: if you have astigmatism, there will be three additional numbers on your prescription-
    • SPH (S) refers to the spherical part of your prescription, which is the degree of nearsightedness or farsightedness.
    • CYL (C) refers to the cylinder (the astigmatism), and it can be a positive or negative number; it measures your degree of astigmatism in diopters. The higher this number, the more astigmatism (= the more your cornea is shaped like an ellipse, instead of a globe).
    • Axis is a number from 0 – 180 that reveals the orientation of the astigmatism, describing exactly where the difference in curvature is occurring.
  • ADD: this is a correction factor for when you need a different prescription for near vision, such as for presbyopia. This number is always a plus/+.
  • PD: stands for interpupillary distance. It is a measurement of the distance between the center of one eye to the center of your other eye, and it is an important piece of information. PD ensures that your eyes match up with the optical center of your eyeglasses lenses.

People often worry when they see a major difference in the numbers for the right eye to be very different from the left eye. However, this is quite common.

Check the date on your eyeglasses prescription

There’s one more important number on your prescription – the date of issue! Now that you’re fully informed about how to read your eyeglasses prescription, it’s time to make sure you had an eye exam in the last year, and that your lenses are truly optimizing your vision. Book an annual eye exam with our eye doctors in Las Vegas, Spring Valley, Summerlin, , , and , Nevada, to ensure your eyeglasses prescription is accurate!

Reading glasses – How will I know if I’m ready?

When you pick up a book or your smartphone, do you need to stretch your arm and hold it further away from your eyes to see the words? When you go grocery shopping, do you need to take a step back from the shelves to read the ingredient lists? These are all signs of presbyopia – a common and normal age-related vision condition – which means it’s probably time to get reading glasses.

Blurry close vision is a clear sign to visit our friendly Las Vegas, Nevada, eye doctor, at Yesnick Vision Center for an eye exam. We’ll check your sight for near and distance to prescribe the best eyeglasses to give you 20/20 vision.

Signs that you need reading glasses

  1. Over age 40 – while everyone’s eyes change at a different pace, most people develop presbyopia (a normal part of aging) in their forties. This common vision condition makes it hard for your eyes to focus on nearby objects.
  2. Computer work tires your eyes – do you experience fatigue and heavy eyelids when working at your computer or any type of detailed work? Untreated presbyopia can strain your eyes. In addition to blinking more and taking breaks to let your eyes rest, the right pair of bifocal/multifocal eyeglasses or reading glasses can boost your eye energy.
  3. Halos appear around lights – when your lens can’t focus light properly onto your retina, it can cause fuzzy vision, especially when loking at lightbulbs or headlights.
  4. You need brighter light to read – if you always feel that the room is too dim, it can also be a sign that you need reading glasses. Older people tend to need more light to achieve 20/20 vision.
  5. Headaches – straining your eyes can lead to headaches, especially the type of pain that you feel right behind your eyes. Painful vision is a sign that you need to visit our Las Vegas, Nevada, eye care center for an eye exam.

Still not sure you need reading glasses? Schedule a comprehensive eye exam!

Dr. David Yesnick will check your vision and eye health thoroughly to issue your precise vision prescription for eyeglasses or reading glasses. We’ll also inspect the health of your eyes to make sure your symptoms aren’t due to another problem; such as eye disease. Remember, eyes and vision change with age, so regular follow-up eye exams are essential!
