Polarized sunglasses are best for cutting out reflected light. Reflected light is the biggest cause of glare. Reducing reflected light, e.g. from a wet road or car bonnet, will improve your visual comfort significantly more than just wearing a basic tinted lens.
What are the best sunglasses today ?
Today’s sunglasses, with or without prescription, can be improved with an addition called polarization. A polarized lens cuts out 100% of reflected light from a horizontal surface. As a result, the image you see with polarized lenses is a bit darker than usual, but objects look crisper and clearer, and details are easier to see.
As a polarized lens reduces the amount of light entering your eyes they should not be worn at night time to reduce glare from headlights. Furthermore glare from headlights is not reduced by a polarized lens in any event. A car driver needs to wear clear, non tinted lenses to drive at night time.
People who use polarized sunglasses for long stretches of time often say they are less tired than usual after hours of battling sun glare. People who fish, find polarized sunglasses drastically cut the reflected glare and help them see into the water.
A polarized lens greatly improves driving safety in bright daylight and improves visual comfort when there are any bright shiny surfaces, such as car body panels and shiny roads.
All Zeiss lenses have an inbuilt UV blocking filter in the lens matrix. All Zeiss lenses cut out harmful UV radiation which accelerates the ageing process in your eyes, cause skin wrinkles and accelerates to formation of cataracts.
Polarized prescription lenses are an individual product and are made to order for each prescription. Virtually all prescription lenses have a correction for astigmatism, that means the focusing part of your lens needs to sit one way round and the polarization needs to be fitted correctly to cut out the glare from reflected light.
So, yes, polarized lenses are the best sunglasses to cut out glare especially for driving. Some plastic windows and old classic car windscreens show odd patterns in which case the polarized lens would not be suitable.
