The sport you play can make a huge difference in the kind of protection you need. Basketball, baseball, and racquet sports are a common source of eye injuries, mainly from balls and racquets hitting the eye at very high speeds. Chlorine in swimming pools is another problem, because too much can damage the cornea. If you play an outdoor sport, you'll need eyewear that filters the sun's ultraviolet (UV) light, which can cause permanent damage. Types of protective eyewear include: goggles, face masks, shields, sunglasses and scuba masks. Remember, everyday glasses don't provide enough protection from impact. For most sports, you should wear polycarbonate goggles. Polycarbonate is very resistant to impact, so it's the only reasonable choice in sports where your eye might encounter a ball, racquet, finger, etc.
