I'd like to get some feedback as to whether using the sunglasses that highlight the yellow of the ball would also be good for indoor tennis? I want to play in a tournament over the Holidays but I don't see the ball very well at this particular club. The lighting is sub-par, in my opinion. I struggle with depth perception and such. I'm wondering if the same principal would apply with the competiitive sunglasses that highlight the optic yellow color? This could help me focus in on the ball and maybe block out the dark greens and greys. thoughts?? thanks for any feedback.
