I prefer to wear glasses over contact lenses.
Glasses are typically worn to correct vision, an example would be reading glasses or glasse for nearsightedness. Though for some people contact lenses look better and are less annoying.
That is true. I like glasses better as they are cheaper and I think easier to clean for me and put on.
Yes glasses are much more convenient for some people understandable. Some types of glasses are used to protect against visible or nearly visible light or radiation?
Yes like sunglasses! They protect against UV radiation I think. And also look cool. Strange I have to wear contacts to wear sunglasses tho. 
I apologize for the awkward question mark at the end of the last sentence. And yes some sunglasses are for style and some protect against UV (ultraviolet) electromagnetic radiation. UV radiation constitutes roughly 10% of total light outputted by the sun. So it is very present in the sunlight that hits the earth.
Wow. You are pretty knowledable about that. I typically do not wear sunglasses when I go outside though, since I just have regular glasses.
I totally understand i dont either unless the sun is really bugging me. But sunglasses are a pretty cool thing, in the early 1900's they were called sun cheaters, cheaters was actually slang for glasses in America. Pretty weird!
Hmmm...I didn't know that they were called that. I guess our current slang for them would be "shades." I wonder why they called them cheaters tho?
in the lenses. Some types of safety glasses are used to protect against visible and near-visible light or radiation. Glasses are worn for eye protection in some sports, such as squash.
Glasses wearers may use a strap to prevent the glasses from falling off during movement or sports. Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck, to prevent the loss of the glasses and breaking.
Sunglasses allow for better vision in bright daylight
shades and mirrorshades. Many blind people wear nearly opaque glasses to hide their eyes for cosmetic reasons.
Sunglasses may also have corrective lenses, which requires a prescription. Clip-on sunglasses or sunglass clips can be attached to another pair of glasses. Some wrap-around sunglasses are large enough to be worn over top of another pair of glasses. Otherwise, many people opt to wear contact lenses to correct their vision so that standard sunglasses can be used.
