I've had both eyes done and got along great. Instead of having both eyes 100% long distance and then would have to always use readers for up close reading, I had the right eye at 100% long distance and the right eye at 50/50, so that most small print, I do not need a reader. I do need a reader for real small print. I still have prescription glasses for reading and watchin TV, because if I only had readers, I would need to take them off or look over the top of them if I wanted to see the TV screen. Sorry to go on and on. My best advice if anyone has this done, is make sure you adhere to the instructions regarding the eye drops, no skipping or stopping them prematurely.
