Picture this: Your opponent hits a solid backhand shot across the net. As you run to return the tennis ball, you prepare your racket to fire it back. All of a sudden, however, you notice that you can't see the ball very well. A glare is disturbing your vision.

You realize that you need tennis sun glasses.

Tennis sun glasses will provide you with the ability to see everything clearly - without the sun, glare, or any other factors distorting the clarity of your eyesight. When picking out a pair of sun glasses for tennis, you must keep several key points in mind.

First of all, you must ensure that the tennis sun glasses you choose are custom fit, so that they stay in place on your face. This is important because tennis is a high-intensity sport. All of the running around and movement may cause tennis sun glasses to easily fall from your face and onto the court. The last thing you want to do is step on your sun glasses and break them. Therefore, it is in your best interest that when purchasing your pair of sun glasses, you have them custom fitted to your face first.

Next, when buying tennis sun glasses, you should make sure that you get the proper color lens. Different color lenses are good for different activities. In tennis, a teal blue-tinted lens in your tennis sun glasses will give you the best vision possible. A teal blue-tinted lens will provide high levels of contrast, while at the same time muting out all colors except yellow. Because of this, the tennis ball will stand out to your eyes. This type of lens in your sun glasses typically allows 33% light transmission.

Other important features to consider when purchasing tennis sun glasses are: comfort, protection, scratch resistance and UV protection level. You will want to purchase a pair of sun glasses that have templates and nose pads that are firm, yet provide adhesion for when you sweat. Also consider buying sun glasses for tennis that have wrap-around frames. These frames will protect the sides of your eyes from wind or any bugs or debris in the air. Your sun glasses should also have scratch-resistant lenses that provide 100% protection from the UV rays of the sunlight. This protection will keep your eye sight healthy so you can beat your opponents for years to come.
