I was born with congenital cataracts and have had several operations on my eyes. My vision is around 20/30 with contacts, but I'm legally blind without them (20/400).

I know my condition isn't quite the same as yours, but here's some advice:

1. Do not get surgery unless it is absolutely essential. If you're only mildly nearsighted, then stick with glasses. Your eyes are very intricate, and any amount of surgery is going to do additional damage.

2. Sending time on the computer, even 18 hours a day (as I sometimes do), won't have major long-term impact on your vision. I specifically asked my doctor about this in May when I went in for a new contact prescription. Time on the computer will make your eyes tired, but that's all. Just take a break and you'll be fine.

Keep in mind I am not a doctor, and you should consult your own ophthalmologist.
