I’ve noticed recently that sometimes things don’t look the same in both eyes. It’s as if the vision in one eye is darker. The best example is if I look at my phone screen and it’s on a white page eg google, everything looks like the expected bright white when I use one eye, but when I close that eye and open the other eye to compare it it looks much more greyer, dulled and a bit darker in that eye. Everything is still sharp and clear, it’s just things look much darker especially white. It’s not constant- it happens on and off but it’s most noticeable when I wake up. I had an eye test recently which was fine and I don’t wear glasses right now.
does anyone know what this could be?
