yeah i have a similar thing with sound, certain kinds of sounds and frequencies really put me on edge
i'm starting to suspect it relates to some mineral deficiency, because adding magnesium and potassium to my diet seems to be reducing it, but it's probably different with eyes, even still, if your iris doesn't contract enough to lower the light level it will seem overly bright and that can be painful, and come to think of it, i've noticed this also with my own eyes, maybe it is related to neuro/muscular stuff and electrolytes
what happens here is because of how cloudy it often is here in Sao Vicente, sometimes there is just a little sunbeam shining right on a bright white painted object, like the little chapel/clocktower over across the other side, and i get that bloom effect on it, like, the light whites out stuff, and i also notice that the tiny little people i see walking around up there, at the same time their little dots of light seem excessively strong
so it could actually indicate your eyes are not constricting enough for the light level... probably lowering the brightness of the device will help in this, possibly cutting the blue down on the display may help, though green is the really bright colour, blue tends to make it hard to focus on stuff (that's why night shooting glasses tend to be amber)... green is the brightest of the colours, but also the sharpest
