Only the Best Polarized Sunglasses
(San Francisco, CA, USA)
I think best polarized sunglasses are the ones that fit you well, before anything else.
I have light sensitive eyes that are made even more so when I suffer a migraine. As much as I would love to spend all my time during the day hiding in dark room, it is not only impossible, but unhealthy.
I didn’t know about polarized sunglasses when I bought my first pair of UV sunglasses
, so I just had a regular UVA/UVB pair.
They helped, but the glare reflected off of things like windows, chrome on cars, and anything else shiny, especially if it had a sharp point of light, was still extremely painful to my eyes.
One day, I learned in a biology class about polarizing filters, which are filters that completely cancel out, or absorb, all but one plane of light that passes through them.
They are great for viewing crystals under the microscope. At any rate, my professor held a pair of sunglasses
he was wearing up to a square of polarized filter to show how the concept worked.
He rotated the filter until the plane of the light passing through it, was perpendicular to the plane of light passing through the lens.
This prevented any light from passing through the two, making them appear black. I was so impressed with this I went out and got a pair of the best polarized sunglasses as soon as I could afford them.
Best polarized sunglasses work amazingly well to cut down glare. They also can affect what I see in other ways.
It is easier to see when it is foggy outside, since instead of being able to see all the light reflected around in the fog, I see only the one plane of that the lenses allow through.
Rainbows appear more vividly when I have my sunglasses on. I can also patterns from the manufacturing process of tempered glass. That last one isn’t really a pro or a con, it’s just interesting.Polarized Bifocal Sunglasses
