Although you may have heard of them, you are still not quite sure what are polarized sunglasses. There is a lot of misconception and mystery surrounding the way these sunglasses work and what it is they do. If you have questions about these sunglasses, you can find out more about their unique features and benefits by reading the information below.
So, you may now be wondering what else makes these sunglasses so special. These lenses on these sunglasses are coated with a special chemical. The chemical is actually a film that is designed to reduce glare.
Glare occurs when the sun light is reflected off of a solid surface. It can also reflect off of water. Polarized sunglasses neutralize the glare, and you will be able to view more objects more clearly. They will also help minimize the dangerous effects of UV rays.
How Does Polarization Work?
The rays of the sun reflect light in all directions. This means that when a ray of sunlight hits a surface that is flat, the reflected light immediately shines toward your eye and the light is magnified. As a result, a glare is produced.
Glare can not only reduce depth perception, it can also reduce the amount of light that is transmitted through the lens vertically and horizontally. The glare from the sun can even leave you temporarily blind.
Most of the traditional sunglasses that are on the market are developed to reduce the amount of light that is transmitted. However, polarized sunglasses have chemical filter on the lenses that help the lenses absorb and capture horizontal light waves. The vertical light waves will still be able to pass through both lenses. Light is only able to travel one way through a polarized lens so the risk of glare is eliminated.
What Are The Different Categories Of Polarized Lenses?
The first type of polarized lens is the .75mm lens. This lens is made from very thin sheets of chemical film. This is the best choice when you are not worried about resistance from impact. For example, these types of polarized sunglasses are great for activities like golf, walking or running.
The next type of polarized lens is the 1.1mm. As assumed, they have a slightly thicker layer of chemical film than the .75mm. However, these sunglasses do not offer enhanced polarization or improved glare reduction. As a matter of fact, they are generally more expensive due to the added layer of film.
Is There A Difference Between Polarized Lenses And Tinted Lenses?
Even though tinted lenses can help reduce brightness, they are not effective at eliminating glare. Also, it is important to note that just because a lens is tinted, that does not mean it will offer your eyes protection from UV rays.
Always check the tag on every pair of sunglasses you purchase. See if they offer any level of UV protection. Also, keep in mind that dark tinted sunglasses that do not offer UV protection can actually cause harm to your eyes than not wearing any sunglasses at all. They cause your eyes to dilate, and allow more light to enter the inner areas of the eyes.
So, what are polarized sunglasses? They are designed to protect the eyes from UV damage and glare via a chemical film filter specifically designed to eliminate sun glare.
