Anti-reflexive coating on eyeglasses is a necessity for those whose job demands continuous staring at the computer monitor or driving at night.
Anti-reflective coating is a layer applied to the surface of eyeglasses and other optical devices to reduce reflection. It is made of metal oxides and is applied to both sides of the eyeglasses.
Benefits
- Glasses with anti-reflective coating give better night vision. They help you see in better contrast and with much more clarity than the lenses without such a coating.
- Since anti-reflective coating reduces reflection, it improves the contrast in image by excreting stray light.
- It greatly reduces glare while working in direct sun or a brightly lit room.
- Studies have shown that coated eyeglasses ease the stress on eyes that occurs by continuous staring at the computer monitor.
- Applying this coat becomes even more important if you wear reading glasses made from materials with high index of refraction. Such materials produce more distracted reflections, which interfere with night vision.
Care
These glasses need frequent cleaning as the coating easily gets scratched and dirty quite often. Any smudge on it is easily seen, and scratches can never be removed. The best way you can care for your glasses is by using a specified cleaning method.
- Rinse the glass frequently in lukewarm water. This would reduce the possibility of the glass getting scratched.
- You can clean the entire surface with soapy water. Use either a hand or dish soap to wash the eyewear.
- Wash the glasses thoroughly with running water. Shake the glass gently to remove excess water.
- Wipe it dry with a lens-cleaning cloth.
Properties
- Stability at different temperature.
- Resistance against frequent wear and tear.
- Resistance against wiping.
- Adhesive strength.
- Low reflection at the maximum sensitivity of the eye.
You can even use this coating on your sunglasses. Remember to never apply this layer on both sides of the tinted lens, as it may become too dark.
