Do sports sunglasses block your vision?

[Kansas]

I am going to get some sports sunglasses.But I am wondering if they will block my vision from looking completely to right/left, up/down?

If sports sunglasses can block your vision ,they are useless for you . Generally speaking ,a pair of good quality sports glasses won't block your vision .But if they are too small for you , your peripheral view may be affected to some extent . when you are looking left, right, up, or down, you don't usually only move your eyes,your head moves too so the glasses won't block your vision.

Definitely no. You don't see things with your eyes only, your head can also move, understand that?
