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?
