Polarised sunglasses block glare from light reflecting off flat surfaces better than any other type of sunglass lenses, making them very popular among people who spend a lot of time outdoors, on the road and particularly near water. But sunglasses aren’t just for people who love boating, fishing or going to the beach. Anyone who is bothered by glare outdoors can benefit from these advanced sunglass lenses. Polarized sunglasses can be helpful for driving, too, because they reduce direct reflective glare from the hoods of vehicles and light coloured pavements. Sunlight scatters in all directions, but when it strikes flat surfaces, the light that is reflected by the surfaces tends to become polarised — meaning the reflected light beams travel in a more uniform (usually horizontal) direction. This creates an annoying and sometimes dangerous intensity of light that causes glare and reduces visibility. Polarised lenses have a special filter that blocks this type of intense reflected light, reducing glare and discomfort.
In general polarised lenses provide you with a much more relaxing and enhanced quality of vision.
Gradient Sunglass lenses are dark in the top third with a gradual change in tint lightening towards the bottom. They were originally designed for pilots who require a full tint against the very bright above cloud sunlight however a lighter tint to read their instruments and dials. Drivers also appreciate the way in which gradient lenses allow them to read their dashboard. Those reading in sunlight may also use gradient lenses as the entire lens is fully protective against UV light.
Anti Glare Back Surface
Anti Glare / Anti Reflection coatings on your sunglass lenses stops bright sunlight from bouncing off the back surface of your lenses and into your eyes. This distracting glare can cause a reduction in the quality of vision and comfort provided by your sunglasses. Premium sunglass brands now included this option on standard on their top of the range non-prescription lenses. Therefore it is now becoming more common for sunglass wearers to request the same technology in prescription form.The decision to add this option to your prescription sunglasses is the ultimate finishing touch and provides you with the ultimate lens package.
