When my eyes were affected by bright lights, and the glare off of parking lots, oh, and also, lightbulbs had haloes around them that were never there before, I went to my eye doctor and discovered I had been growing two nice thick cataracts. I noticed other changes too. If i closed one eye and looked at a flower, the color of the petals were different if I close my other eye and looked at it. One eye saw them as pink, the other as maybe a darker pink. The colors were all off. Turned out, cataracts. I literally thought the lightbulbs in my house were getting dimmer... I was 36. I've had R.O.P. since I was born, legally blind. Having the cataracts removed made a big difference, but I was still legally blind all the same.

Yup! I only have one eye that's affected right now though, so I just close it. Dark mode everything I can and have sunglasses whenever I go outside.

Yeah, I have some version of this. You're likely doing the obvious (always have sunglasses with you, I buy like 5 pairs at a time, dropping like 100 because they're easily lost). I switch (reverse) the colors on my computer and phone, which helps A LOT. iOS has classic invert (invert everything) and smart invert, which sometimes isn't that smart, try them out and see if they help. Windows Magnifier lets you reverse the screen, and Mac OS has an accessibility feature in Universal Access that will also reverse the screen color for you. On Linux I use somethign called xrander-invert.

I've noticed that smoking weed helps with photophobia a bit, in case that's some kind of option for you. I think it's the THC that does it in case you're picking out strains.
