Sunday, July 24, 2016 5:11 PM Size and Coverage (8) are inter-related. Look at this cyclist’s glasses, and then look again at the image of the young woman at the beginning of the course. Size and coverage is a key factor in comfort and they are different. Comfort therefore has more than one meaning and coverage describes how the frame and lenses deliver protection (glare and UV) while they make the long, wearing times outdoors, a pleasure.

Monday, July 18, 2016 12:10 PM Molecules in a polarizing filter are long in one direction (horizontal) and short in the perpendicular direction (vertical). Electrons can freely oscillate along the length of the molecule, absorbing or reflecting the light energy, while they are unable to oscillate very far along the short direction.

This month, we’re going to take a little blast to the past. In my previous blue blocker articles, I’ve discussed the variety of lens treatments available for day-to-day wear, in order to enhance patient vision, diminish stress, and reduce the likelihood of potential illnesses and disorders later in life, such as AMD. What I haven’t discussed is blue light protective lenses for outdoors.

The Physics of Polarizing Filters

By Ari Siletz
Monday, June 16, 2014 1:00 PM To see how polarized sunglasses work, it is convenient to think of light as a wave moving along a string. Just like a wave on a string, a light wave wiggles transversally to its direction of motion. And just like a wave on a string, the plane in which the string oscillates can have different orientations.
