I grew up nearsighted pretty badly in my left eye (20/200, or -3.0) – my right eye too, but to a much lesser degree (20/35 or -1.0). I hated the idea of sticking stuff in my eye every morning and glasses didn’t appeal to me much as a kid, so I just went around with everything kind of in 2D. Sports like shotput and wrestling were obviously not too badly affected, and soccer even was not that bad (the ball is big and slow enough that parallax and ball size can give you enough cues with one eye to know where the ball is), but tennis didn’t work out so well for me. Around college I started wearing glasses as an experiment, mainly encouraged by girls who thought they framed my face nicely. And so it went for years – which mainly worked. But sometimes it’d be challenging – like when scuba diving, skydiving, snowboarding, or going to 3D movies and having to wear two sets of glasses at once. Sometimes I like to just let my nose rest and take my glasses off my face. So I started thinking about getting laser eye surgery.
