I have been using a glossy monitor (LG5K) for over a year now and I swear it is affecting my eyesight.
I heard that it can happen as it’s more difficult to focus on glossy surfaces but I was unconvinced and didn’t expect it to have any impact on my general eye-health. Maybe the covid lockdown and lack of gym/exercise has been a factor but I don’t think I will get a glossy monitor again (and really hope Apple bring out an affordable 6K matte display!)
I’m curious what you are using, and, if you’re using a glossy monitor, do you feel it’s impacted your eyesight at all?
