Polycarbonate lenses are thinner and lighter than standard lenses. Polycarbonate lenses are made from a similar material to that of bulletproof glass, these lenses are 10 times more impact resistant than standard plastic lenses however this material is relatively soft, subsequently polycarbonate lenses need a scratch-resistant coating to prevent surface scratches. These lenses are for low-to-moderate prescriptions of 0.00 to +/- 3.00. If your prescription is higher than this, please see ou

High Index 1.67 are recommended for prescriptions ranging from +/- 3.00 to +/- 6.00 to keep the lenses the thinnest possible.

This lens comes with UV400 treatment and scratch resistance as standard.

Transitions or sometimes called Photochromic lenses are lenses that darken into sunglasses on exposure to ultraviolet (UV) radiation. Once the UV is removed (for example by walking indoors), the lenses will gradually return to their clear state.  These features make Transition or photochromic lenses a great convenience, by reducing your need to wear prescription sunglasses in most outdoor conditions.

Polarized sunglasses are specialized lenses designed to reduce glare and increase contrast sensitivity. Glare distorts the true color of objects and makes them harder to distinguish. Unlike traditional sunglasses, polarized sunglasses selectively block out glare instead of dimming the entire field of vision. Polarized sunglasses are popular with sports enthusiasts, including skiers, golfers, bikers and joggers, fisherman, as well as the general public.

There is a huge variety of colors shades and intensity that prescription glasses can be fashion tinted in. Fashion tints provide variety and create special looks for both men and women by accenting, complementing or bringing out their eye color.

(AR) coating is a type of optical coating applied to the surface of lenses to reduce reflection. Anti-reflection lenses decrease reflection making eyewear look better, less glare is particularly noticeable when driving at night or working in front of a computer monitor. The decreased glare means 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.
