You may not realize that many sunglasses do not reduce glare from reflected sunlight, even though they reduce brightness and the amount of light that is transmitted through the lenses. Severe glare can distort your view and even reduce your depth perception. If you are looking for sunglasses for boating or fishing, or other outdoor activities where glare can be a problem, polarized sunglasses may be a great option for you.
The lenses of polarized sunglasses are different from traditional tinted lenses because they have a film applied to the outsides of the lenses that filters light waves differently. Instead of just reducing brightness, these coated lenses actually absorb reflected horizontal light waves and only allow the vertical light waves to pass through the lenses.
These lenses will allow you to see with more clarity and can also help mitigate the negative effects of UV light on your eyes. There are 2 main types of polarized lenses. The first kind has a .75mm layer of film on the lenses. These lenses provide the polarizing effect and are a great option for you if you do not need impact resistance. The second kind is usually more expensive and has a 1.1mm layer of film. You will want these thicker lenses if you need impact resistance in your glasses. They do not provide any higher levels of polarization.
If you have experienced problems with glare in the past, polarized sunglasses can make a big difference in your ability to enjoy outdoor activities on the water or the snow. They are available in many different styles and designs, so you’re sure to find the ones that are right for you.
