How Polarized Sunglasses Keep the Sun Out of Your Eyes

by Boston Laser

The bright rays from the sun can be particularly hazardous during this time of year, when the glare from the light bouncing off snow and ice can make it difficult to see while you’re driving. You can use polarized sunglasses to reduce this glare’s impact on your eyes, consequently reducing the chance that you’ll veer off course. But have you ever wondered how these sunglasses work to prevent the sun from inhibiting your vision?

According to Kierstan Boyd and Devin Harrison of the American Association of Ophthalmology, the special chemical that coats polarized sunglasses acts as a special filter for the light, blocking horizontal waves that bounce off reflective surfaces while letting in the vertical ones. Boyd and Harrison describe the lined-up molecules of the chemical as a sort of window mini blind for your eyes: “Only light that passes through the blind’s openings can be seen,” they write.

The only drawback is that the filter on polarized sunglasses makes it difficult to discern the images on LCD screens. If you’re using sunglasses to help you see better while you drive, though, perhaps that’s for the best to keep your eyes on the road!

-Avoiding contact with contaminated services
-Not putting one’s hands near the mouth or nose
-Not sharing utensils or drinks

Not Effective

-“Folklore” advice, like telling kids not to go out with their hair wet

Psychologist: ‘Using Technology is About as Associated with Well-Being as Eating Potatoes’

“Using technology is about as associated with well-being as eating potatoes,” psychologist Andrew Przybylski told Wired. In other words, though there’s a lot of information floating out there about how harmful technology can be, it tends to be more statistically significant than practically significant. Smoking cigarettes, for example, has an effect on wellness 18 times greater than screen use. That’s not to say that technology isn’t bad for you in any way, just that more conclusive research is needed. (via Wired)
