I keep my monitor on as low of a setting as I can manage. I used my colorimeter while adjusting the color levels as well, so I could further reduce the brightness of my monitor while keeping the color accuracy. But, when playing darker games it can be rather difficult to see what's going on, so I'll usually switch to a different mode to see better. As far as preserving my vision is concerned, a major concern I have is glare. Having glare on a screen can apparently increase eye strain by a lot, which somewhat troublesome for me. I sit directly next to a window and have overhead lights that I have no realistic way of preventing glare from, because they're at such a sharp angle from me.
I think for really optimal viewing, it would be great to have OLED monitors, but for some reason they still don't exist... The closest thing you could probably do is maybe find a small 24 inch TV and use that, but the lowest I've seen in the US is 32 inch, so you'd probably have to import one from Korea or Japan where people don't mind smaller TVs. In the meantime I have a really nice CRT monitor from the tail-end of their existence, and it's really nice for watching stuff, but as a nearly 15 year old monitor, it is fairly finicky to use at time, and there is of course the concern that using a CRT monitor could speed up the rate of eye damage beyond typical aging.>Do you keep the three metres of distance to the screen in a well-lit room like the anime tell you at the episodes' beginnings?
I'm pretty sure the the old saying "you shouldn't sit too close to the TV" is because of CRTs. Although having leaded glass greatly reduces the amount of x-ray emissions, there is still a non-negligible amount of exposure if you sit within a few feet of them. Simply sitting farther back greatly reduces the amount of x-rays you can be exposed to, so that's why it's suggested you sit farther back. Relatedly, if I'm remembering right, I believe larger CRTs required higher voltages to drive the display, and likewise higher brightnesses directly correlates with higher plate current and greater electron emissions, so in the case of really huge TVs from back in the day, it probably was true that for all intents and purposes you might have wanted to be seated 3 meters back. Of course, the amount of x-rays being emitted is still fairly low, but the cumulative exposure is the concern since people would regularly use TVs or computer monitors. I'Post too long.
