All spectacle lenses reflect some light, reducing the amount of light that enters the eye to form visual images. This can have an impact on vision, especially under low-light conditions such as driving at night. Lens reflections can also cause glare, further reducing vision in these situations.
Anti-reflective (AR) treatments reduce lens reflections and allow more light to enter the eye for better night vision. Regardless of the lens material, spectacle lenses with an AR treatment transmit approximately 99% of available light to the eye.
By eliminating surface reflections, anti-reflective treatments also make your lenses nearly invisible and thinner. Whilst everyone could benefit from an anti-reflective treatment, it is especially beneficial for people with high prescriptions and professions in which cosmetic appearance is important. As the name implies, anti-reflective treatments allow others to see your eyes, not the reflections in your lenses!
