I don't know if it works with kids. I'm a programmer, I look at the computer monitor probably about 8 hours per day. What I did was that I wear a glass with weaker prescription so that when I look at the computer monitor, the characters are slightly blurred but I can still read them. I did this for about 6 month and my prescription went from -5.75, -5.25 to -4.75, -4.25. Actually when I started even with the -5.75, -5.25 prescription my vision is about 1.2 or so. Unfortunately this technique seems to only work at the beginning. In the months following the first 6 months my vision didn't improve anymore so I stopped it. But I consider spending $300 to knock off 1 point prescription from each eye quite worth it. By the way I never got any headache from wearing weaker prescription glasses (and I did get headache before when wearing stronger prescription glasses). Actually I found it comfortable to wear weaker prescription glasses when reading, because my eyes don't feel stressed. That is actually the optometrist at Costo suggested to me.
