Absolutely wear tinted goggles if you are swimming outside! They are totally worth the money. Be sure to buy a pair with a good tint to protect your eyes from the UV rays. Even if you are not swimming the backstroke, tinted goggles are a must when swimming outside. Tinted goggles will shield your eyes from the sun’s reflection on the water, which can be very harsh on a bright day. The most common tinted goggles are gray or blue colored.  There are even goggles with a “mirror” tint on the outside of the lens (Think: Highway Patrol), and no one will know you are watching them swim.
