- Summary
Polarized sunglasses are designed specifically to reduce glare so that you can see clearly in situations where you might otherwise squint or be blinded by reflected light. Glare is caused when light hits a reflective horizontal surface, causing light beams to be scattered horizontally. This can overwhelm photoreceptorsin the retina of the eyes, inc...
Polarized lenses themselves do not block UV light from the sun which can damage the eyes. They are simply designed to prevent glare, not only during the day but possibly at night as well. The polarization of lenses is beneficial in that it: 1. Increases your visual comfort 2. Sharpens the contrast between light and dark 3. Allows you to see true co...
Glare can be dangerous, especially when driving because it distorts the true color of objects and makes objects harder to see. Glare has been linked to many pedestrian deaths and traffic accidents. Polarized sunglasses can be especially helpful in situations like: 1. Driving: This is especially true on extremely hot days when the combination of hot...
Polarized lenses aren’t right for everyone. There are three specific situations in which they may be more problematic than useful: 1. Visual disorientation: Some people feel dizzy or disoriented when they look through polarized lenses, particularly at normal light levels. Others say that the lenses make everything look “more 3D,” potentially interf...
Polarized sunglasses are designed to reduce glare caused by light this is reflected off horizontal surfaces. The chemical processes used to make the lenses are vertically oriented. Polarized lenses are helpful for reducing glare and increasing color perception when you are driving, boating, or playing sports. Polarized lenses aren’t right for every...
Expect students to look through the sunglasses and a polaroid film and figure out that the film must be oriented horizontally because sunglasses are vertically polarized. By doing this, they learn that polarized sunglasses change the light intensity.
One interesting property of light is polarization. When reflected off of certain surfaces -- such as water -- light gets polarized. Polarized sunglasses can eliminate reflected light off of water and similar surfaces because of its polarization. See the section on sunglass technologies for details.

Mar 29, 2022 · By holding your lenses in front of an LCD backlit screen, you can verify that they are polarized. The lens should get darker as you turn it. Because LCD screens have crystal filters that rotate the polarization axis as light passes through, this is possible.
