Primary life bottleneck now is chronic eyestrain from too much indoor time and failure to acquire suitable visual hygiene habits like 20-20-20 (stare >20 feet away for 20 sec every 20 min). Even if I did that I don’t think it would be enough. Need long unmasked walks 🤓🤬

I'd imagine bright background lights might help with this. I'm building some with .
Indoor environments are about 1% as bright as being outdoors.

Yes, lumens per square meter (lux). You can get a decent measurement from a number of phone apps sense most phones auto-adjust screen brightness.

Visible spectrum or overall? And we don’t notice why? Log response and pupil contraction I’m guessing....?
Yeah, log response. Well outside the visible spectrum you aren't get anything indoors. Lumens are actually based on our eyes rather than just physics of light, it's the radiant energy multiplied by a bell curved shape response that peaks in green region.

visible spectrum. log response. pupil gives about 200x range, retina other 1,000,000x. we did not have sensors with similar range until about 2017.
