I hardly ever wear sunglasses and my eyesight seems fine. Does it really matter if you wear them or not?

Hope this link helps. For all information about sunglasses you can check out http://useinfo-sunglasses.blogspot.com/... .
They protect your eyes from damaging UV rays, especially if you wear polarized lenses. Sunglasses also keep you from squinting due to glare, which reduces muscle tension in your head and keeps you from getting tension headaches.
Other than helping you delay "squint line" type wrinkles, I'm not really sure. There may be some advantage to blocking harsh UV rays from your eyes.
The safari guides do not wear sunglasses because their eyesight would be impacted if they lost their glasses. I wear transition lenses, which when darkened, take the place of sunglasses. Just don't stare at the sun, with or without sunglasses.
Unless you are doing specific work that requires eye protection like weilding, then you technicaly dont NEED to wear sunglasses.Although alot of doctors will recomend that you wear glasses, they arent a nessesity in all situations.
There are a few reasons behind wearing sunglasses.
two of which i can think of offhand.One is that they lower the amount of light comming into your eye. which helps in the long run because an extended amount of UV radiation on your eyes can damage your retinas over time which can lower your ability to see in general.The second reason covers polarized lenses, which take the glare off objects with reflective surfaces, which can be an anoyance to deal with, and also helps with the first reason since a glare multiplies the UV radiation on your eyes, sort of like a magnifying glass.Even so, they are not a real requirment, so if you dont care to wear them either because they are too cumbersom and uncomfortable, or you just dont like the look. then there is no need to.
I always think they look super cool.
Good to protect your eyes from UV rays but you also need sunlight through your eyes and skin for basic good health
Well, overexposure to UV rays increases your chances for developing certain types of cataracts.
