1.Look at the two most common eye guards sold - closed and open plastic guards.
2.Decide what's more important to you - full protection or unobstructed vision. Closed guards provide the most protection, but scratches and sweat will collect on the lens with use. Open guards, while providing ideal protection for glancing balls, may not be as effective in stopping a direct frontal hit to the eye.
3.Make sure the guards come with a strap rather than hinged arms. A strap is safer and less likely to move around during play.
4.Buy eye guards that are comfortable.
5.Wear them every time you play. There's no sense risking an eye injury when a simple piece of plastic can prevent it.
Guards that go over eyeglasses are also available. Consider wearing contacts when playing racquetball just as an added precaution.
Keep an extra pair in your bag in case the first eye guard breaks.
