I feel incredibly lucky that I don't suffer from any of these symptoms, as I sit, and have sat, in front of my computer for ~14 of my available waking hours each day for the past... 10 years? 8 hours a day at work, and I then come home and game for 3 or 4 more, sometimes as much as 9 or10 additional hours, and have not yet felt anything as described here. I may do these exercises naturally, as part of my existing hab…

Re: Computer Vision Syndrome
#92Anyone know of a break-taking app that watches your activity and can wait until you've lost focus on your work before reminding you to take a break? Something like the alarms that wake you up at the right point in your sleep cycle. It would probably need to have a cut-off eventually, but I'd hate to be interrupted in the middle of tracing some complex logic if there's a perfect stopping point 10 minutes later.

#93over 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.
How do you know it was computers and not just age in general?

Re: Computer Vision Syndrome
#95My retired optometrist friend recommended that I wear reading glasses with a very low power at all times while using the computer, and I do that now. They're .75x or 1x, I can't remember. I don't need them--nothing is blurry without them--but they help your lenses to relax by doing some of their work at close distances. The condition he wants me to avoid is called nearpoint stress, but sounds very similar to me (a la…

Turning down the brightness had the opposite effect for me. My monitor at the time "turned down the brightness" by reducing the duty cycle of the backlight. This caused flickering that was imperceptible yet caused much eyestrain. Actually turning up the brightness, moving the monitor as far back as possible, and using yellow-tinted Gunnar lenses have made a huge difference for me. Edit: This is the technique used to…
Basically every monitor with a LED backlight controls brightness by PWM. It only causes problems if the frequency is too low. (Contrast with fluorescent lights: every single fluorescent tube in existance flickers, but only some flicker slowly enough that people can notice. https://www.youtube.com/watch?v=bjyhFyUN_zQ Ditto CRT monitors, back when they were still used. Refresh rate of 60hz is flickery and annoying, ref…
I heard some monitors may revert to PWM below a certain brightness threshold, but assuming the information on that page is accurate, not getting PWM-free monitor is probably a sub-optimal purchase decision.

Well no cure aside maybe not looking at a backlight. I really wish there were marketed displays without a backlight. There's got to be a way.
I've been wanting this for ages. And more simply, I want brightness controls that go all the way down to zero.
# echo 100 > /sys/class/backlight/intel_backlight/brightness
This sets the backlight brightness. I'm not sure what the units are, but it can go all the way to 0. If I shine a very bright light at the screen (like sunlight), it is readable at 0.Re: Computer Vision Syndrome
#100Flux + EyeLeo is the way to go for me, I know my job already damaged my eyes but this helps reduce head aches and dry eyes.
