I've always found the different types of eyeglasses interesting. How about you?
I've never needed any. What types are there?
As you suggested, there are glasses for for eyesight, sunglasses for protecting the eyes and then safety glasses for workers.
What about glasses for fashion? I like to match from my head to my toes.
Sunglasses
Sunglasses or sun glasses (informally called shades) are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized or darkened. In the early 20th century, they were also known as sun cheaters (cheaters then being an American slang term for glasses).
The American Optometric Association recommends wearing sunglasses that block ultraviolet
. There are also safety glasses for welding, which are styled like wraparound sunglasses, but with much darker lenses, for use in welding where a full-sized welding helmet is inconvenient or uncomfortable. These are often called "flash goggles" because they provide protection from welding flash. Nylon frames are usually used for protective eyewear for sports because of their lightweight and flexible properties. Unlike most regular glasses, safety glasses often include protection beside the eyes as well as in front of the eyes.
