Here is a used item that I am selling at a bargain: dark brown polarized sunglasses.Sunny days are lovely, but you want to enjoy the summer fun without doing potential damage to your eyes. So you should wear sunglasses that are dark enough to do the job.This includes those labeled as “UV 400,” which blocks all light rays with wavelengths up to 400 nanometers.
The pair listed here will block all UVA and UVB rays. They’re used and the scratches are visible, but the arms are not bent in any way and fit firmly to the head. Size: medium.Carrying case included.Note: UVB rays are the most dangerous, making sunglasses and sunscreen a must; they don’t go through glass. Glare and reflections can give you trouble too, so have your sunglasses ready if you’ll be around snow, water or sand, or if you’ll be driving (windshields are a big glare source). Sunlamps, tanning beds, photo-sensitizing drugs, high altitudes and proximity to the equator also put you at greater risk.
