I've had this, when I was silly enough to not wear protective eyewear when growing.
I know it may sound silly to many people, though grow lights are bright as fuck these days. The ones I started with were fine, but my current ones on maximum power are so bright they affect my vision when I look into my tent for longer than a few minutes.
Just wanted to give a heads up to anyone getting into or considering growing plants indoors, as this isn't something I've even seen mentioned much: if you have sensitive eyes, definitely grab some lenses for grow lights they make an incredible difference. They're much stronger than they used to be, and the linings in tents help spread and reflect this too.
Without the lenses my vision is like this picture, for a good half hour or so before it goes back to normal, in one eye. Genuinely worried me! Be safe!
