Heavy computer use linked to glaucoma: study
Mon Nov 15, 6:11 PM ET
PARIS (AFP) - Heavy users of computers, especially those who are short-sighted, may be at risk from glaucoma, a disease that can cause blindness, a study published in a specialist journal on Tuesday says.
Japanese doctors assessed the sight of more than 10,200 Japanese workers, measuring them for visual acuity and signs of glaucoma.
The volunteers were also asked to fill in questionnaires about their computer use, at home or in the office, and any history of eye disease.
A total of 165 workers, or 1.6 percent, turned out to have suspected glaucoma, characterised by tunnel vision or blind spots.
Those who were heavy computer users -- defined as working onscreen more than eight hours a day -- were twice as likely to have glaucoma than light or medium users.
In addition, of the 165 with glaucoma, 136 had myopia.
The study appears in the Journal of Epidemiology and Community Health, published by the British Medical Association (BMA).
Glaucoma is a slow, gradual disease of the optic nerve that often goes undetected. Among the identified risk factors are smoking and high blood pressure.
The authors speculate that the optic nerve in short-sighted people may be more vulnerable to computer stress than in normal-sighted people.
If so, that would be dramatic news, given that so many hundreds of millions of people around the world now work at computer terminals, at work and at home.
They stress though that the study has limitations, notably in that most of the volunteers were male and this may have skewed the outcome. Further work is needed to probe the suspected link, they say.

considering that i suffer from myopia and sit infront of a computer for 8 hours a day at work, and then more when i get home.. i guess this can't be a good thing ..
and TA probably isn't helping either .. :(

I take that a step further and condsider it preventative medicine :)
That is a mildly disturbing article though considering my computer use at work and home :(
I would like to see their list of controls in that study...are we talking high quality monitors, set at a sufficiently high refresh rate, proper resolution, etc. If this is about eye strain, all of those factors could drastically skew the results... |

| I love my Samsung 1701MP LCD. I used to get eyestrain with an old Viewsonic CRT monitor after an hour. I had to take constant breaks. With this LCD, I am free of that stuff. Perhaps LCDs aren't applicable to this study? |

The eyestrain comes from the low frequency of the monitor (default 60hz). If you have a good monitor, you'll be able to turn it up.
LCD's all run at 60hz but it doesnt scan like a CRT so there's no eyestrain.

Radiation is minimal compared to a cell phone and other wireless devices.
The glaucoma is probably casued becuse you are staring at a lightbulb for extended periods of time. Yes, looking at a monitor is like starting at a light bulb, and people don't stare at light bulbs. |

Hah! No crap i just got diagnosed with that in my left eye yesterday :(
I have the beginnings of it and now i have to wear glasses when i'm in front of the pc and reading a book :(
I used to get massive headaches when i was on the pc and eventually decided to go to the eye doctor to find out what was going on... Turns out my left eye is under too much strain and he diagnosed a beginning of glaucoma. It's a pain because now i have to be super careful and go to the eye doctor every 6 months to get my eye checked out :nervous: |
