A lens treatment is a special additive that either bonds with the lens, or is built into the lens during the lens manufacturing process. Lens treatments are available as individual additions to lenses, and are also commonly bundled into single lens products for convenience and maximum benefit to your eyes.
Have you been wondering about Blue Light?
The eye doctors at Peninsula Vision answer questions about how blue light affects your eyes.
Q. I have read that blue light is bad for my eyes, can you explain what blue light is, and why it’s bad for my eyes?
Blue light is short wavelength visible light. It is harmful to your eyes for two reasons: 1. It causes damage to your rods and cones and may increase your risk of age-related macular degeneration
. 2. It can cause increased glare, decreased low contrast vision and increased eye fatigue.
Q. What is the source of blue light, and when am I exposed to it?
computers, and televisions) and the sun, which emits more blue light than any other source.
Blue light is essentially everywhere and we encounter its harmful effects in everyday
Q. I understand that there are glasses I can wear to protect my eyes, is that correct?
Yes this is correct. With the new Zeiss DuraVision BlueProtect Coating, your eyes will be 100%
protected from the damaging effects of blue light.
Q. How does Zeiss DuraVision BlueProtect protect my eyes?
Zeiss DuraVision BlueProtect specifically targets the blue-violet light rays coming from LED lights, TV screens, computers or digital devices. Blue light blocking lenses reduce the transmission of short wavelength light and reflect the light off of the lens surface. This filters the blue light from getting to the back of our eyes while still allowing good transmission of higher wavelength visible lights. Reducing the eye’s exposure to this type of blue light helps prevent retinal cell damage and phototoxicity.
Q. Are protective lenses available for everyone, including children?
Q. Are there different types of coatings that protect from blue light, and can you explain the
differences, and which one you recommend?
Zeiss does not have any other coating that protects from blue light. We do offer PhotoFusion which offers protection from blue light. We recommend PhotoFusion Brown, grey will work but it is not as effective as Brown.
Q. Do these types of lenses look different from regular lenses?
Yes they have the appearance of a tonelite tint and the reflective colour has a purple/bluish hue.
Q. Do I need a prescription for these types of lenses, and where can I buy them?
No you do not need a prescription. You can buy them at our optometry in Niagra Falls
, or through any optometrist’s dispensary.
