Anti-Reflective Eyewear

Anti-reflective eyewear refers to eyeglasses and sunglasses that have an anti-glare coating. The coating consists of multiple layers of metal oxides designed to block light, and improve both the performance and appearance of eyeglasses.

This type of coating blocks excessive light from entering the eye: 

  • Preventing glare 
  • Reducing reflections and halos around lights 
  • Making eyes more visible through lenses

Why is anti-reflective eyewear used?

Anti-reflective lens coating is designed to improve the cosmetic appearance and to enhance the performance of glasses. The coating blocks light to reduce the glare seen through glasses and the reflections others see on lenses. With less reflection, lenses look far thinner and eyes are much more visible in photographs.

Night driving

Anti-reflective eyewear is particularly beneficial when driving at night. The anti-glare lens coating reduces the halo effect that occurs around headlights and streetlights in the dark.

Computer work

This type of eyewear is also recommended for people who work with computers all day. The lens coating reduces eyestrain from battling glare on a monitor, allowing people to work on a computer for longer periods without difficulty.

BlueTech Lenses: An anti-reflective coating that that blocks out specific wavelengths of blue light from reaching the patient’s ocular tissue. Crizal Prevencia and BluTech lenses reduce eyestrain and fatigue and are believed to be a major preventative step against macular degeneration. Specifically blocking the narrow band of blue light from 415-455nm which is the “retinal damaging” light. BluTech is a lens material infused with melanin, a natural pigment found in the iris of the eye, to help filter out the same blue light (415-455nm). The melanin gives BluTech lenses a yellowish hue, and is available for any prescription. The coating filters out harmful blue-light rays that can contribute to macular degeneraton, as well as UV rays that are an important cause of cataracts. 

You encounter blue light in everyday activities. Fluorescent lighting, electronic screens (phones, tablets, computers, TVs, etc.), and the sun emit damaging high-energy blue light.

Benefits of anti-reflective eyewear

Glasses wearers often wonder whether anti-reflective coating is a necessary investment. In general, the benefits of anti-reflective eyewear justify the added costs. The primary benefit of anti-reflective eyewear is the prevention of glare and reflections on lenses, blocking excess light that can lead to pupil strain. Anti-reflective eyewear also eliminates distractions from halos while driving at night.
