I know there can be a lot of factors causing eye strain using a monitor. Im building a DIY no backlight monitor so i have to use a TN Panel. Actually i have not found clear&reliable informations on what specs are better to reduce eye strain:
1. Size 24" vs 27" vs 32"
2. Pixel density 93ppi (FHD) vs 123ppi (WQHD) (for example on 24")
3. Colors more vs less (16bit vs 24bit vs 30bit)
4. Frame rate control yes vs no
5. Response time like 1ms vs like 5ms
6. Anti glare coating yes vs no
7. Frequency like 60hz vs 144hz ..
8. Low blue light
9. Color temperatur
-flicker free (not high flicker frequency like 10khz)
-good viewing angle
Something else i missed like contrast/brightness ?
My opinions on the mentioned points above:
1. A big screen could be worse as you have to move your eyes more over the day, but is it better to stare at one direction for a long time on a lower screen…
2. Having a higher resolution might could be worse if text and icons etc are smaller then usual on a fhd. I never used wqhd so might you can set up programs and ui (text, icons) at the same size like fhd…
3. More colors could exhaust eyes and brain, but colors outside of screens are not limited aswell… definitly less saturated.
4. This actually sounds very bad for eye strain, but i havent seen a monitor witouth so far
5. no clue.
6. "Anti glare coating" reduce reflections and glare which sounds like relief, but it might could lead to worse viewing experience -> more exhaustion… but i could imagine having reflections and glare is way worse.
7. Higher frequencys make everything more smooth, we get closer to reallife movement, but probably causes exhaustion for eyes and brain. Is it actually good to see fast movement the whole day, but in this case is laggy 60hz the solution… Maybe low refresh rate of einks might contribute to less eye strain aswell.
8. Not sure how low blue light is implemented, the sun actually also emits blue light at a lower amount. Cutting it out completly could lead to fatique. The best might would be to simulate color temperature with the exact properties of the sun over the whole day, but at night ?
flicker free i see no disadvantages same for viewing angle.
