What is Blue Light?
Emitted from the sun, blue light is naturally occurring in the world around us. On the spectrum of visible light (light that humans can see), blue light has the highest energy and the shortest wavelength.
It is also sometimes known as blue-violet or violet light, which is where ultraviolet (UV) light rays that are just beyond our perception get their name. Much like ultraviolet light, blue light has both dangers and benefits to our health, particularly to our eyes.
As people move from their computer to their tablet to their phone, more and more of these symptoms are seen, and in younger and younger people. Computer glasses offer a solution to reduce the strain on your eyes and your exposure to blue light radiation. If you experience any pain or discomfort call Yesnick Vision Center at 702-500-0525.
Computer glasses reduce eye strain by adjusting the focus slightly so that your eyes feel like they are focusing on something further away. They also have a tint to remove the glare and block blue light from entering into your eyes.
They specialized glasses designed to emphasize comfortable intermediate viewing, helping your eyes more easily focus on the computer screen with less effort and making computer viewing over an extended period of time noticeably more comfortable.
The lenses are equipped with special coatings or lenses that are made to filter the harmful blue light waves. By filtering out harmful HEV rays they make extended computer use more comfortable while reduces the risk of developing macular degeneration in the future and other vision health issues.
The Effects of Digital Eye Strain
ZEISS DuraVision BlueProtect
The ZEISS DuraVision BlueProtect lenses filter out wavelengths of blue-violet that are shorter than 440nm — the range of light which is considered by eye doctors to be the most dangerous.
By blocking only these very high energy wavelengths, the ZEISS DuraVision BlueProtect coating protects your eyes from retinal cell damage, phototoxicity, and disruptions to your sleep cycle while allowing beneficial frequencies of blue light through. You will be protected with clear and true-color vision while still enjoying the benefits of blue light.
Shamir Blue Zero
Shamir uses a unique polymer formula to produce these high-tech lenses. The Shamir Blue Zero High Index 1.67 and Trivex lenses block up to 98% of high energy blue light in the 415-435 nm range. The Shamir Blue Zero Polycarbonate lenses block up to 50%.
This allows you to enjoy significant protection from blue light while still enjoying crisp, clear, and true-color vision. On average, Shamir Blue Zero blocks about three times the amount of harmful blue light as compared to standard clear lenses.
These lenses from Hoya provides blue light protection along with excellent contrast and reduced glare for clear and comfortable viewing of digital devices in a way which reduces eye strain and improves color perception.
