I feel ya Xin. I'm only 18 but have terrible eyesight.. I'm talking worse than -7 in my right eye. This has forced me to be more conscious of my vision, and what I've noticed about eyesight is that it fluctuates quite a bit depending on my habits. At least mine do, so I assume other people's might too.
Whenever I'm stressed and don't get much sleep, such as during finals week, my vision greatly decreases and my astigmatism worsens. Same goes for when I do a lot of up close work, and also when I find myself in a new environment that makes me feel nervous and self conscious. To battle these decreases, I've tried several things and I'll tell you the ones that have worked. First thing is obviously to become more emotionally relaxed. Stop stressing out, or remove most stress from your life. This isn't always possible, I understand, but learn to relax. The second thing is to periodically look away from the computer screen and look 30 or so feet away for a few seconds. I try to do this every 10 minutes or so... It's probably better to do it more frequently than that though. That's really all I do, and just these two things have prevented my vision from deteriorating rapidly like it used to. Whenever my vision worsens, I do those two things and it goes back to it's current state unlike in the past when it would continue decreasing.
Also, for up close work, I use my older eyeglass prescriptions. My vision deteriorates A LOT if I do up close work using my current prescription.
