As my optometrist said about reading glasses, "They're a dollar at the dollar store."
I wear one contact lens, with the bare eye a +2.75, so I can use my bare eye rather than glasses. Then, I use my contacted eye to look at the composition, as fuzzy as it is, to make sure it's worthwhile. Works for me. I do keep a +3.25 pair of glasses in the toolkit, but they're rarely used.
