This may not be totally relevant but I used to have 20/200 vision. several years ago I also developed cataracts, had them operated on and went from wearing coke bottle thick glasses to not needing them except when reading. The optometrist about getting reading glasses and his comment was yes but that I would be better served by buying some of the cheap ones that they sell at almost every drug store or supermarket. I have even bought a six pack of them off Amazon. They cost less than $10 a pair
