What is an Anti-Reflection Coating?
Anti-reflective or anti-reflex (AR) coatings are a type of optical coating applied to the surface of lenses to reduce reflections.
Optometrists dispense anti-reflex lenses because the decreased reflection makes them look cosmetically better, and they produce less glare, which is particularly noticeable when driving at night or working in front of a computer monitor.
The decreased glare means that wearers often find their eyes are less tired, particularly at the end of the day. Allowing more light to pass through the lens also increases contrast and therefore increases visual acuity.
