What is the purpose of anti-reflective coating?

To change the color of the lenses

To prevent scratching on lenses

To reduce glare and reflections on lenses

The purpose of anti-reflective coating is primarily to reduce glare and reflections on lenses. This type of coating works by allowing more light to pass through the lens instead of reflecting off its surface, which can be particularly beneficial for wearers of glasses in various lighting conditions. It enhances visual clarity and comfort by minimizing distracting reflections that can occur from artificial lights and bright environments.

By improving light transmission, the anti-reflective surface helps to limit issues like eye strain and is especially advantageous for individuals who spend significant time on screens or driving at night. The coating does not alter the color of the lenses, prevent scratching, or affect the firmness or durability of the lenses, which sets it apart from other types of lens treatments that serve different functions.
