While it is recommended to wear sunglasses all year round, it is important to wear the correct pair to get maximum protection for your eyes. Polarised lenses have become a popular choice when buying sunglasses, but is it worth the extra cost? They offer many benefits over their non-Polarised counterparts, and should be considered carefully when buying sunglasses. But, how beneficial are they?
Polarised lenses have a virtually invisible filter built into the lenses to eliminate the amount of reflecting light that enters the eye. This filter does not only reduce glare, but increases visual clarity and comfort by making images appear sharper and clearer. They are available for prescription sunglasses and
non-prescription sunglasses and are sometimes even worn indoors by people whose eyes are light-sensitive, patients who underwent post-cataract surgery and those continually exposed to bright sunlight through windows.
Polarised lenses for driving sunglasses or sports sunglasses are a good investment if you spend a lot of time on the road or practicing outdoor sports. Objects will appear clearer, because of the reduced glare on reflective surfaces and will cause less strain on your eyes. Glare is not only uncomfortable, but it
interferes with the perception of depth, distorts your view and can cause brief periods of blindness.
Polarised lenses block harmful Ultraviolet rays from entering the eyes, where dark tinted sunglasses without UV protection can potentially be more harmful to your eyes. The reason is that the darkness of the lens can cause the pupil to dilate and allow harmful UV rays to enter the inner parts of the eyes. So, if you do
opt for dark tinted lenses over Polarised lenses, make sure that they offer 100% UV protection.
Benefits of Polarised sunglasses
The amount of light blocked by Polarised sunglasses is far more improved than your average pair of dark tinted sunglasses. Dark tinted lenses only dim the visual spectrum and do not protect your eyes from the intensity or damage of excessive light. Listed here are some of the benefits of Polarised lenses:
Most Polarised sunglasses provide protection against Ultraviolet light which is important in supporting a healthy eye sight. UV rays are dominant in winter as well and because of the lower setting of the sun during winter time it is recommended to make sunglasses a priority. Just as we put on sunscreen to protect our skin from the sun, it’s critical that we protect our eyes from UV rays.
