My husband is trying glasses from Zenni Optical (. Com). You may want to look at them or a similar online glasses place if you do wind up needing multiple pairs of glasses cheap. You do need your prescription, but your eye dr. has to give it to you, so you can do it. I can't say that particular site is good yet, because he just ordered on Friday, but the prices, options, and autonomy impressed him. The concept behind it is good. I am cautious, but his hyper expensive special glasses and lenses with all the luxuries for $175 is unheard of. Usually I think they're over $380 with insurance, so we at least are trying it. Transition lenses was an option, I believe he said.
