You would have heard that ultraviolet (UV) rays can cause skin cancer. That’s why skin specialists and ophthalmologists suggest sunscreen lotions and sunglasses with (UV) protection. However, you need to check more than just the label on the sunglasses to determine which ones are the best suited for you. Just because a pair of sunglasses is expensive, does not necessarily mean that it provides ultimate protection, there are cheap sunglasses available in the market which provide quality protection against the sharp rays. Whether you plan to buy replica polarized sunglasses for men or a pair of designer eye wear, following are different kinds of lenses you can choose from to safeguard your eyes:
- Polarized Lenses
These lenses reduce glare and provide extra security. Generally, polarized lenses do not provide UV protection unless they are treated specifically with UV coating. These lenses help in eliminating the glare produced by reflective surfaces like dashboards, wet roads or other cars etc.
- Photo-chromic Lenses
Photo-chromic lenses darken when they are exposed to UV radiation. So once you are out in the sunlight, the lenses will gradually darken in approximately a minute, and when you are away from the UV light, the lens gradually comes back to its standard transparent state. These too can provide adequate UV protection when you need it while retaining the clear standard plastic state when not required.
- Polycarbonate Lenses
Polycarbonate lenses are by far the most effective in providing protection against the harmful UV rays. They provide 100% protection and are 10 times more impact-resistant than glass and plastic lenses. Polycarbonate lenses were generally used for safety glasses for industrial purposes, however they are now becoming popular among sports wearers too. These are the safest options to provide children complete protection as they are break resistant and lighter.
- Infra Red Lenses
Infra red lenses are great for mountainous or high altitude activities as they provide protection against infrared radiation.
