over the last 10 years of being on a computer for at least 10 hours a day my distance vision has been obliterated. i used to have 20/15 vision and now i have 20/50 vision. I'm positive the screens are the issue. My toddler nieces stand a foot away from tvs and every time i see it i beg their parents to not let them subject their developing eyes to that.
