Tries sunglasses to help me with a medical problem. I've tried sunglasses. They filtered out the UV but didn't seem to help much. I thought a while ago that maybe I should try to filter out more sunlight and not just UV rays, so I looked for sunglasses that filter out more sunlight, they call them category 4 sunglasses. I tried them. They look good on days when the sun is very bright, but look a bit dark on cloudy days. They are of good quality and for good quality the price is not bad. They seem to be helping my tremors so far, time will tell. Light has a specific effect on the brain.
