Currently I own two pairs of prescription glasses (I'm near sighted). One pair is my basic rectangular frame. The other are aviator sunglasses. I really enjoy playing with my aviators as the field of view is large and I feel like I hit better. With the rectangulars I feel like I get jammed and don't see the ball as well (same prescription). I feel like the narrow rectangular frames are distracting, especially on serve. The other day I dropped the rectangulars on an oriental carpet in our family room and found them...with my foot. :shock: So I'm off to get new glasses this weekend. Current plan it so get two aviators for tennis, one polarized and the other clear for night games. Is there a better shape for tennis with respect to field of view and depth perception? Do those fancy sports glasses with swappable lenses make a difference? I read somewhere that certain lens colors enhance the ball's color. Is that true? Thanks in advance!
