I'm definitely going to work on my can removal technique to make it more spec-friendly.
Another dangerous area for me is drying my hair with a towel with specs on. I nearly lost them in the gym locker room last night when I decided to give my hair one last towel rub before I left. Should've taken my bins off first, I'm so lucky to have caught them on the way down.
To be honest I have much better vision with contacts. I have the right prescription in my glasses, but you just don't get full-range sharpness across the whole field with specs. Things are a little iffy on the extreme edges, and of course there's the chromatic aberration (colored edges) and barrel distortion. My first excursion out of the opticians onto the streets of Manhattan was a wild trip. I honestly thought I might die, everything looked so freaky. I'm kind of used to them now.
Only reason I got them was because my optician told me that I should give the contacts a rest for a couple of days a week. But now I'm wearing them every day because, well, I look so damn hot in them and they bring all the girls to the yard. Still like my contacts though. I wore one-day Acuvue and they are really amazing, so comfortable to have a fresh pair in every day.
