Glare blindness

[Guest guest]

There's a fair amount of literature on nutrient deficiencies relating

to night blindness and how vitamin A, lutein, zeaxanthin, and so on,

can help. What about problems handling significant brightness and

glare, though? I think I have very good night vision (as one might

expect considering my diet) but I've always had a problem with

brightness. Looking up into the sky to catch a fly ball or to hit a

tennis serve, for example, have always been extremely problematic on

sunny days, and on bright days I tend to have trouble tracking a

tennis ball as it passes quickly through patches of bright sun and

dark shade. Of course other people tend to have some difficulty with

these problems too, but not nearly as much as I do.

Are there any nutrient deficiencies associated with this sort of

problem?

TIA,
