Consider the single vision polarized amber lens Oakley Flak Jacket XLJ for tennis.
The polarized amber lenses (yellow/brown) increase contrast for tennis, just like hunters, anglers and drivers have used them to increase contrast.
The polarized amber lenses are not too dark - you can play until pretty late in the evening with them, or on overcast days.
And they are not so dark that the ball looks like a black blob the way it does with really dark sunglass lenses.
The Flackjacket style wraps around your face so little light enters from the sides.
Also, wraparound sunglasses with no bottom rim and relatively small nose pieces do not leave blind spots.
They are a pleasure to drive with.
It will be rare you will need to play with clear glasses.
