Why You Shouldn’t Rub Your Eyes

While it may seem like a harmless action, rubbing your eyes can actually cause a lot of damage. There are a number of different reasons that people rub their eyes and for the most part, it does more harm than good. While rubbing your eyes might feel really good in the short term, it’s best to find other ways to get relief from your symptoms. 

Why People Rub Their Eyes

Rubbing your eyes can feel good for a number of reasons. First of all, it can be therapeutic as the pressure can be soothing and can stimulate the vagus nerve, alleviating stress. It can also lubricate your eyes by stimulating the tear ducts and can flush out or remove dirt and particles. 

However, you don’t want to make eye rubbing a habit because there are a number of ways it can cause damage. Let’s take a look at some of the reasons people rub their eyes and some ways to avoid it.


If you are rubbing your eyes because you are tired, think again. Rubbing your eyes frequently can contribute to bloodshot eyes and dark circles due to the breakage of tiny blood vessels in and around your eyes. If you are already tired, this can add to an even more worn-out appearance.


Itchy eyes can be caused by a number of reasons including allergies, inflammation or infections. In any case, rubbing them can often make things worse. For allergies, rubbing the eyes can actually make your eyes more itchy because it can spread more allergens around. Further, there is an inflammatory cascade response that is aggravated by eye rubbing, which can cause the intense fluid swelling and redness often associated with allergies. 

If you have an infection, rubbing your eye can cause more irritation, and often spreads the infection to your other eye, and potentially to the people around you. In fact, that may be how you got that infection to begin with. The hands carry a good amount of germs and bacteria, and your eyes are an easy access point for these germs to enter. Touching something, even as common as a doorknob or towel, which someone else with an eye infection also touched, is a common cause of conjunctivitis and other contagious eye infections. 

Something In Your Eye

If you have something in your eyes, rubbing may seem like the natural response to get it out. However, this can cause the object to scratch your eye and damage the cornea. Rubbing may occasionally push a foreign body deeper into the cornea making it more painful and difficult to remove. 

Dry Eyes

Dry eyes can be temporary, resulting from environmental or physical circumstances, or chronic, due to a condition like blepharitis in which the eye produces a poor quality tear film. If you rub your eyes when they feel dry, it can exacerbate your discomfort and even sometimes cause infection if you don’t wash your hands first. When your eyes don’t have enough tears, they may not flush dirt and germs out as readily as well-lubricated eyes might. 

Other Eye Conditions

Eye rubbing can be especially risky for people with existing eye conditions such as glaucoma, thin cornea and progressive myopia, as it can worsen eyesight. In glaucoma the eye rubbing can lead to an increase in eye pressure which can lead to nerve damage and eventual vision loss. In individuals with a thin cornea, eye rubbing can exacerbate the problem sometimes resulting in a condition called keratoconus which seriously distorts vision.

Alternatives to Eye Rubbing

Eye Wash

Your eyes actually have built-in mechanisms to flush out particles and irritants, but when these don’t work, eye flushing, eye drops or artificial tears might bring relief or remove foreign bodies. If you think you have a foreign body in the eye, first flush the eye with saline, eye wash or water. If you have something stuck in your eye that you can’t flush out, go immediately to an eye doctor. 

Eye Drops or Cool Down

For chronic itching or allergies, speak to your eye doctor as there are remedies such as antihistamines, mast cell stabilizers or even steroid eye drops that can be prescribed to alleviate symptoms. If no prescription eye drops are available when needed, try cooling down by going to a cool area and putting cold water on a paper towel over the eyes for a few minutes. Cooling the eye area will reduce symptoms as the blood vessels constrict, while heat tends to make the itch worse.

If you have dry eyes there are a number of options available for treatment which include drops or procedures to clear out tear ducts to improve eye moisture. 

Remember, no matter how good it may feel to rub your eyes, there are potential consequences, some of them serious, so next time, think twice!


Ocular Migraines

Migraine Awareness Month:

An ocular migraine is any migraine headache that involves a visual disturbance such as flashes of light, seeing stars or zigzags or the appearance of blind spots in the visual field. Ocular migraines can interfere with your ability to go about your daily tasks such as driving, reading or writing, however, the visual symptoms don’t last long and do go away completely once the migraine has passed.

What is an Ocular Migraine?

The term ocular migraine may refer to a couple of different conditions. Firstly, migraines with auras often have eye-related symptoms that precede the actual headache. An aura is a physical symptom that is experienced usually within 5 minutes to an hour before a migraine comes on, and can include:

  • Blind spots (scotomas) or partial vision loss
  • Flashes of light, spots or zigzag patterns
  • Visual, auditory (hearing) or olfactory (smell) hallucinations or disruptions
  • Tingling or numbness
  • Mental fog, trouble finding words and speaking

These types of ocular migraines commonly appear by obstructing a small area of vision which spreads gradually over 5 minutes.

A second type of ocular migraine is when you actually experience temporary vision loss or disruptions (flashes, blind spots, zigzag lines etc.) during or immediately following the migraine headache. Ocular migraines can also sometimes appear without any head pain at all. They may also be called eye, ophthalmic, or retinal migraines.

What Causes Ocular Migraines?

Similar to classic migraines, the exact cause of an ocular migraine is unknown. Genetic predisposition seems to be a factor to some extent, and having a family history of migraines does put you at greater risk.

While they don’t know the cause, experts have seen that spasms in the blood vessels and nerve cells in the retinal lining at the back of the eye are associated with ocular migraine symptoms.

For some, there are certain environmental triggers, or a combination of factors, that cause migraines. These differ on an individual basis but can include:

  • Stress
  • Bright lights or loud sounds
  • Strong smells
  • A sudden or drastic change in weather conditions
  • Eating, or exposure to, certain food substances such as, alcohol, caffeine, nitrates, MSG (monosodium glutamate), artificial sweeteners and tyramine.

Since triggers are different for everyone it’s advised to try to identify yours by keeping a journal to track your environment, diet and lifestyle habits, when you experience a headache.

Treatment for Ocular Migraines

Treatment for ocular migraines is usually not necessary as the symptoms typically resolve themselves within 30 minutes. It is advised to rest and avoid doing things that require vision and concentration until the headache goes away and the vision symptoms cease. If you are experiencing an ocular headache:

  • Lie down in a quiet, dark room when possible
  • Massage or apply pressure to the temples and scalp
  • Apply a damp towel to the forehead

If you experience auras, taking a migraine medication when the aura occurs, can often reduce the intensity of the headache that follows. In other words, you can use the aura as a warning sign that a headache is coming on and treat it preventatively. Your doctor may prescribe a pain reliever for associated head pain and, if migraines are chronic, a preventative medication may be given.

It’s important to note that if you are experiencing any unusual visual symptoms or an increase in frequency or duration of symptoms, you should see an eye doctor right away to rule out any serious, vision threatening conditions. Symptoms such as floaters or flashing lights can also be a sign of a retinal tear or hole.

If you get migraines, among the best ways to prevent them are to keep your mind and body healthy by eating nutritious foods, getting enough rest and managing stress effectively.

Why Does My Child Need a Pediatric Eye Exam?

Reasons to Visit Your Pediatric Optometrist in Las Vegas, NV

Kids are not just miniature grown-ups. The visual system of children of all ages, from infants to teenagers, has unique needs; they are at risk for different eye conditions than an adult. Our pediatric optometrist is specially qualified and experienced in checking and treating kids’ eyes. If you are reading this and thinking to yourself – My child isn’t complaining… so why should we schedule a pediatric eye exam?, Dr. David Yesnick has a number of reasons to share with you! Read on to learn why it is essential to visit our Las Vegas pediatric optometrist.

Eye Exams Prevent Problems

Often, kids don’t complain when they can’t see well. They just get used to how their world looks and adapt. However, an undetected and untreated vision condition can interfere with their ability to learn, disrupt behavior, affect social skills, and compromise performance on the sports field. In sum, vision problems can have a huge effect on all parts of childhood! When you bring your child to a pediatric optometrist for a general eye check-up, you are helping to prevent all of these challenges.

Vision Testing is More Than Reading a Wall Chart

To set the record straight, we want you to be aware that a thorough eye exam by our pediatric optometrist in Las Vegas, NV, is not the same thing as a vision screening done in school. Vision testing in school is generally done by a nurse or teacher and not by a qualified eye care specialist. Also, while it can indicate a need for prescription eyewear to correct nearsightedness or farsightedness, this type of basic testing cannot diagnose conditions such as amblyopia (lazy eye), strabismus (misaligned eyes), convergence problems, and trouble with accommodation (focusing). Many vision disorders that our pediatric optometrist may diagnose require treatment with vision therapy or a treatment other than eyewear.

School vision screening also does not inspect ocular health for any abnormalities or signs of disease. Using high-powered magnification, we will inspect the inner eye structure, retinal tissues, and optic nerve.

Red and Itchy Eyes? Your Child May Have Eye Allergies

If your child experiences eye irritation, such as redness, itchiness, or swelling, it could be due to eye allergies. Dr. Yesnick will examine kids’ eyes gently to make a diagnosis and offer effective treatment. A pediatric eye exam is the only reliable way to diagnose the precise problem, because the same set of symptoms can point to various conditions. Eye allergies, eye infection, dry eye, and computer vision can all cause tired, red, watery, and irritated eyes. Once our pediatric optometrist verifies the diagnosis, then we can match the most suitable treatment to relieve your child’s eye pain.

Warning Signs that Kids Need an Eye Exam ASAP

If you notice any of the following behaviors or symptoms, then we encourage you to call and schedule a kid’s eye exam without delay! Being proactive with your child’s vision care is one of the best ways to protect him or her from unnecessary struggles in school and with friends.

  • Squinting, or closing one eye to see
  • Inability to hold a steady gaze
  • Poor tracking skills
  • Avoidance of reading
  • Wandering eye, or crossed eyes
  • Frequent eye rubbing
  • Excessive blinking
  • Head tilting or turning
  • Short attention span
  • Droopy eyelid
  • Red or swollen eyes/eyelids

Dr. Yesnick welcomes kids (and their parents) to visit Yesnick Vision Center for friendly service and expert pediatric eye care in Las Vegas!
