Your eyeglass lenses can control the light reaching your eyes to maximize your visual comfort and better protect your eyes.
Eyeglasses are all about giving you better vision. While sunglasses may come to mind when you think about controlling the light that reaches our eyes, there are many other ways in which eyeglass lenses can alter or regulate light – giving you clearer vision and a more comfortable experience.
Eyeglass lenses can be treated with multiple coatings that drastically reduce the reflection of light on them. This is a standard on Nikon eyeglass lenses, helping you to see better and also look better.
Blue light filtering
By filtering the rays of high-energy blue light, eyeglass lenses can increase contrast and visual comfort. This is particularly helpful for heavy screen users.
UV ray filtering
Special treatments can be performed on eyeglass lenses so they can block the incoming ultraviolet rays, and also reduce the amount of UV rays reflected into the eye from the backside of the lens. To protect your eyes from the sun even further, opt for lenses with a high eSPF (eye sun protection factor) index.
Sunlight reflected on broad surfaces such as the sea, the road, or a blanket of snow creates glare that can be very uncomfortable for your eyes. Polarized eyeglass lenses have a filter that blocks the light reflected on horizontal surfaces and cuts glare, so your vision is much sharper and you’ll feel more comfortable. They are the preferred lens choice for high-performance sunglasses.
One of the most recent innovations from Nikon is a special filter that provides a brightening effect for the wearer (especially for people above age 40). This filter is particularly helpful for people who have difficulty seeing clearly in dim light conditions.
