1.61 High-index Polarized RX ( Gray  / Brown )

 

High index lenses with 1.60 high index are good for people with prescriptions over +/-4.00 sphere, because they are thinner and lighter. Thinner lenses have three advantages: they do not look thick, they do not magnify or minify your eyes when seen by others, and they are lighter. The suggested prescription range is +/-4.00 to +/-8.00 sphere. Thinner, lighter and more expensive than mid-high index or hard resin lenses, high index lenses are a good choice for every day use.

 

How Do Polarized Lenses Work?

Light travels in waves, and the waves of normal light travel in several different directions. Combined, they create the visible light we see, whether it comes from the sun, a lamp, or a candle. But when light is reflected off of a flat surface or a body of water, it travels in only a single direction. This gives the reflected light an uncomfortable intensity that we call glare.

Normal sunglasses work by limiting the amount of light coming from all directions, dimming it so that you find it easier to look around without squinting. Polarized lenses go a step further, taking advantage of the fact that most reflected light travels in only one direction. Using a special chemical process that creates a special coating on the surface of the lens, these glasses filter out all light coming from that direction, virtually eliminating glare.
