I don't need glasses, but both my parents are/were shot sighted. In the case of my dad, he doesn't think glasses or lenses are necessary. He can see perfectly well enough for what he needs to do, and anything that is too far away for him to read, he considers not worth reading.
My mum put up with both contact lenses and glasses for years, until she eventually decided to go for laser surgery. She now needs glasses for reading, but thinks it is one of the best things she ever did.
