What is Anti-Glare Coating? Anti-glare coating, also known as anti-reflective coating or AR coating, is a thin layer applied to the surface of your eyeglass lenses that allows more light to pass through your lenses. This improves your vision by reducing the amount of glare that reflects off of your lenses.
Glare is the excessive brightness caused by direct light or reflected light. It often occurs when sunlight bounces off a reflective surface like water or snow. Phones, tablets, and computer screens lit by LEDs can also cause glare.
Standard plastic lenses reflect approximately eight percent of the light that reaches your glasses, and high-index lenses reflect up to 12 percent of available light.
