I started becoming a bit short-sighted when I was in my late teens, at first only if I was tired. It was mild enough that I didn't start wearing glasses to correct it until I was forty. (I did wear sunglasses a lot - I'm told a lot of blue-eyed people are like that.) I think I gradually got used to the distance being a bit of a blur as I progressed to varifocals, because I could always read without glasses.
Total change after the surgery. I really really wanted my distance vision back and was perfectly happy to wear reading glasses, or varifocals to avoid having to keep taking them off and on. The day after the surgery I was going round saying, see that tree (half a mile away)? Do you want me to count the leaves?
I usually wear varifocals, but have to remember to take them off in the cinema or theatre so I get the distance vision over my whole visual field - and don't have to worry about fingermarks. And outside as well, except then I want to read a map or look at my watch, and maybe that wasn't such a good idea after all. Also, I've got used to having glasses on and feel they protect my eyes when I'm cycling, and of course they're photochromic which is also really good outside. (Great that I can take them off if it rains and still see though.)
A neighbour's husband said that after he had cataract surgery colours changed and he could see a bit into the ultraviolet. I thought he was imagining things, and said so. But then I looked it up, and it's true. The human retina can detect a bit into the UV range, but the natural lens filters out these wavelengths. Some implant lenses are made of a material that lets some UV through. I didn't experience the effect, but I've spoken to several people who describe it. They all like it.
