Get a 70 inch TV and mount it on the wall several feet from your desk. Now you're focusing at close to infinity. Put the computer nearby the TV and use a wireless keyboard and mouse at your desk.

does the type of tv matter? resolution/technology?? Or is the benefit more from the size and distance?? Can a smaller oen work? like a 50inch?

Benefit is distance focus, avoiding eye strain from convergence (think "cross-eyed") when focusing on closeup objects.

Essential: * Flicker free monitor (non-PWM backlight). * Dark Reader browser plugin. Nice to have: * Ambient lighting. * Curved monitors (reduces constant eye re-focusing on large monitors). * Matte finish on monitors, avoid glass to avoid glare. Flicker free is the major one. Many LCD that use a PWM backlight are pure torture at lower brightness levels. Ironically very old LCD with an actual lamp backlight are natur…

> Curved monitors (reduces constant eye re-focusing on large monitors). Isn't this a bad thing? I've been lead to believe one of the most useful techniques to alleviate eye-strain is frequent re-focusing at a variety of distances.

Re-focusing works best with larger deltas in focusing distance, rather than a few millimeters of focus distance change due to monitor curvature.

Compare flexing your arms to stretch, vs. moving your hand by exactly one inch. The former will contract and relax arm muscles from their stable position. The latter requires muscle tension to carry out a precision movement.

For this use I think almost any modern screen will do. Color accuracy typically doesn't matter for developing. And anything over 55" these days will have 4k resolution as a minimum.

Eye health for closeup (e.g. computer) work: Ambient lighting matched to screen brightness, whether light or dark Dark ambience = dilated pupil = 0.5 diopter decrease in lens focus Reduce monitor blue light with F.lux, Apple Night Shift, etc Best light: unfiltered daylight, e.g. window behind computer screen Artificial: high CRI LED, low flicker, low blue (e.g. 2700K Sylvane Truwave) 20-20-20: look out window, or 20+…

Wow this is very good advice thanks!

1 - Turn on night lights for screens (redshift on Linux). If possible, turn it on permanently.

2 - Buy glasses with blue light blocking filters.

3 - No screens at least 30 minutes before bed. Longer if possible.

4 - Avoid reading font that are too small. Zoom webpages on computers and boost font size on cellphone/tablets.

5 - Avoid reading in low light conditions. Low light makes the eyes force.

6 - No staring in direct light. Avoid having a direct light source in your eyes. I turn my lamps upwards so they lit up the ceiling and i do not see the light bulb directly.

7 - When my eyes are strained i find ways to make myself cry a little. When i feel a nice tear in both eyes i tilt my head back and close them for a minute. Tears heal eyes naturally. Afterwards my eyes are super red (like someone who cried) but at least they don't hurt anymore. I usually take a nap after that so the red disappears.

I hope this helps and you find ways to feel better.
