II. Polarized Lens:

• What Does a Polarized Lens Do?

Polarized lenses filter the waves of light by absorbing some of the reflected glare while allowing other light waves to pass through them. The most common illustration of how a polarized lens works to reduce glare is to think of the lens as a Venetian blind. These blinds block light that strikes them from certain angles, while allowing light from other angles to pass through. A polarizing lens works when it is positioned at a 90-degree angle to the source of the glare. Polarized sunglasses, which are designed to filter horizontal light, are mounted vertically in the frame, and must be carefully aligned so that they will properly filter the light-waves.

• The Advantages Of Polarized Lens

Most polarized sunglasses provide UV protection which is important to maintaining healthy eye sight. Just as we put on sunscreen to protect our skin, it’s critical that we protect our eyes from UV rays too.

1. Reduce Glare, Improve Safety On a sunny day, you may notice that objects in the distance appear hazy, or nearby vehicles are reflecting light in a way that is nearly blinding. A polarized lens removes the effects of glare by blocking reflections. This improves eye comfort and allows you to take in the view without squinting. Roadways and water sources are major culprits of glare, and can cause danger to drivers who may already struggle with vision issues. Glare can create a very uncomfortable eye health issue for people with sensitive eyes, and even cause a migraine in patients who are prone to developing them.

2. Better Vision Wearing polarized lenses can reveal colors and images like never before. You will see crisply and cleanly, with a level of detail that may astound you. There are a few circumstances where polarized lenses are not appropriate, such as night driving, flying an airplane, downhill skiing, and viewing LCD screens. The majority of the population will find polarized lenses immensely helpful in improving the clarity and quality of their daytime vision. Ask your eye health provider if polarized lenses are right for you.
