My 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…

It's incredible how small is the Internet. Just today I went to my optometrist because I have problems focusing objets at a certain distance. Turns out that I had exactly the same diagnosis, and I was recommended to buy a 0.5 glasses and use them when I'm staring at the computer or tablet.

You will notice a difference! If I am using the glasses for a while, then take them off and forget to put them back on, I can actually feel the difference.

Wearing them is really nice and when I do it all the time it prevents me from having any trouble focusing on objects at a distance, except for some specific things.

Looking through a scope on a rifle still causes the blurriness, perhaps because of its extreme closeness.

I looked into break timers a while back, but I wanted something really simple that I didn't need to install. I wrote a blog post about how to make a simple break timer with OS X notifications and AppleScript: https://reberhardt.com/blog/2016/02/09/a-dead-simple-break-t...

Thank you, this worked. I just tweaked a bit to run through crontab and added a notification sound for the extra push :)

Anyone 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.

How do you configure it for the situation mentioned in the parent comment?

I have seen a few ophthalmologists seeking treatment for a condition resulting from computer use. I think CVS is a catch all that makes sense on the surface but doesn't really address the damage that has been done. There is some interesting research being done in this area, but it has taken a while for the eye health community to catch up. My story goes back over 4 years ago, one day like the flick of a switch I coul…

I was in a similar situation for a couple of years. Recently I started doing warm compresses on my eyes and it has made a huge difference.

I also recommend changing one thing about your routine every week and keeping an eye pain diary. That will help you identify things that help. It takes some work, but as you said eye health is super important.

I use to get headaches every day (the kind that seem to originate behind the bridge of the nose). One day in effort to reduce the ache (a desperation move I didn't know would work out not) I reduced the brightness level in my monitor to the lowest possible setting. It slightly helped me cope with the rest of the day at work, but I forgot to reset the monitor. The next day I didn't get a headache. Turning down the bri…

That's a great idea. I was just able to very comfortably reduce mine from 100 to 70.

I've been wanting this for ages. And more simply, I want brightness controls that go all the way down to zero.

Seems like there could be a Kickstarter. I'd want a high resolution external eink display as a secondary monitor. The refresh rate would be hell, but it'd be okay for text work.

There's the Dasung Paperlike e-ink monitor:

However, it's only 13.3" in size and, as you noted, it is limited by the refresh rate of e-ink.

I can give only anecdotal evidence. I do this reasonably regularly. It's mainly to combat meibomian gland dysfunction and works by heating up the oils in and around the glands so that the dry build-up clears, and the glands can function a bit more normally. They should be releasing oil throughout the day to keep the surface of your eye from drying out. I think you need to be careful not to overdo compresses, and asso…

I've been doing this on and off for decades now, thanks to blepharitis and the associated gland dysfunction you mention. The fact that I stare at a screen all day certainly doesn't help and I've had to stop wearing contact lenses even though my prescription is quite strong and any sort of glasses screw up my peripheral vision. The downside to the compress (other than the one you mentioned) is the simple fact that I c…

I feel mine started through squinting. My layman's theory is that this introduced tension to the muscles in the area, and around the glands, which inhibited them over a long period of time. It is much better now for me, but like you I can't follow the care instructions to the degree I should. I find a very gentle massage of that area after heat really helps, and I also try to relax the muscles around my eyes and being aware of them becoming tense whenever possible.

Like you say though, it seems to be something you manage rather than cure.

Have you tried flux? It reduces the color temperature making it more mild during afternoon/night hours. It's a life saver.

flux&al adjust colour temp, but be very kind on the backlight any time of the day. Some screens are so stupidly bright it's like staring at a bright bulb all day long. If at all possible use a screen that adjusts backlight automatically according to ambient light. And no, you really don't need that much brightness, just don't turn it all the way down either!

Do you know any good automatic-adjustment add-ons? I'd like to use the OS X option, but it seems to automatically adjust to ~2 notches above what I want. So something to use the same relative changes, but a lower absolute brightness, would be perfect. Right now I just do it by hand.

I think OS X built-in setting work just like that. I.e. turn on automatic brightness, then move slider to make screen dimmer.

I've just tried making the screen really dim, then pointed flashlight onto light sensor. The screen went super bright, but after turning flashlight off it got back to my dim setting.
