"Barring any other ophthalmic problems" indeed.
Went into cataract surgery with scars in both eyes from vitreous detachment few years ago. Opted for distance vision preference, with Toric lens to correct significant astigmatism. Latter corrected astigmatism in both eyes, which I gather doesn't always happen. Knew i would need some sort of eyeglasses to provide reading/computer ability. Having used readers in between eye 1 and eye 2 surgeries, I thought they were too fiddly, so planned on eyeglasses with no or minimal correction on top (depending) and conventional flat top bifocal for close. Left eye came out of surgery less than perfect do to vitreous scarring. Right is lovely. Definitely need sun glasses as the world is wonderfully bright, whites are really white... As I use Sibley and Cornell/Merlin apps on phone to bird, need close vision, I pretty quickly decided to wear eyeglasses setup like above, for that. Having wondered, reading here some time back, if I was experiencing collimation issues in my binocs, (albeit each of them), couple months after surgery discovered in fact I was experiencing double vision at distance. Had to have eyeglasses re-lensed with "prism" lens to fix that. So eyeglasses now required for two reasons. Cant blame surgery for vitreous scars, or double vision. Do think the process led to identification of other issues not fully understood before, and now addressed. Vision definitely better, eyeglass prescription simpler, less expensive. Pretty sure I can pass drivers license eye exam without glasses. Ha!
