- I can wake up and glance at the time instead of having to lift something up and put it centimetres from my face to tell the time.
- I can do sports without the glasses falling off, getting mashed into my face, etc.
- I look a lot better, with a -13 prescription, my glasses were heavy and thick
- My nose and ears aren't in pain from carrying the weight of my glasses all the time.
- I'm not having to constantly adjust my glasses whenever my nose sweats a bit.
- I'm not completely blind any time I have to take off the glasses, like when I take a shower or go in a pool, or especially swim in the ocean where there are big waves.
- I'm not utterly helpless because I'm blind if I lose my glasses. If you're blind without your glasses, and your glasses aren't where you expect, you can't really use your eyesight to find them.
- I don't have to deal with all the problems of using and potentially losing contacts.

For me, before I got laser surgery, I was once swimming in the ocean at a very big and popular beach. I was wearing contacts because obviously wearing glasses in the water is next to impossible. I got hit by a big wave, tossed around, and lost my contacts. Now I was almost completely blind, in a foreign country where I knew almost nobody, and trying to find my beach towel and bag among thousands of others. I actually can't remember how I resolved that problem, but I do remember the massive stress and panic being blind like that caused. When I got back from the trip, I got my eyes fixed within a year.
