I am myopic so i wear glasses. I see double too (whether i'm wearing glasses or not sometimes). I think it's called diplopia. I tried wearing contact lenses years ago but i could not keep my eye open when putting my finger in it because of a reflex. I might try again one day because i think i'm good-looking without glasses and not that much when i'm wearing 'em. What worries me is if one my contact lenses falls i know i won't pick it up to clean it and put it back on my eye because i'll think "don't do that man, it's dirty, you're gonna get an eye disease doing that".
Haha, you don't need to worry about that. Contact lenses are very easy to clean, it takes me about 30 seconds. If they are not fully clean, you will notice it immediately because they either start to hurt when you put them in or your vision remains blurry. When that happens, you just take them out, clean them again and put them back in, no problem
I do advise you to use a cleanser that is specifically meant to clean your contact lenses (instead of an "all-in-one" substance) as it is much more effective. You don't need an "all-in-one" substance, you can save your contact lenses in water when you're not wearing them. At least that's the case with hard lenses (which I wear), I'm not sure about soft lenses but I assume it's the same. I know a lot of people are afraid of their contact lenses shifting and it does look quite scary when that happens (they can shift so far back into your eyeball that you can barely see them) but it's not dangerous at all, you can just shift them back again with your fingers. Also, most contact lenses nowadays are very light blue instead of transparent (doesn't show when you're wearing them, don't worry) so if you lose one, it's easier to find it back. I am very fortunate that my eyes are not sensitive so I can wear hard contact lenses without any problems (hard contact lenses are much cheaper and last way longer than soft contact lenses) but if your eyes are sensitive, I would definitely go for the soft lenses
Anyway, it might take some getting used to in the beginning but contact lenses are really not that uncomfortable, I would never want to trade them for glasses. I don't even notice that I'm wearing them most of the time. I only feel them when the air is dry (moist air is very nice when you have contact lenses, that's why I don't mind the rain too much
), for example during the summer or when the air conditioning is blowing. You definitely want to avoid that. Also, it seriously hurts to get something in your eye (like a grain of sand or a little fly), you need to take your contact lense(s) out immediately when that happens. Other than that, you'll be fine
