Summer is here and swimming is an activity that you can take up which will not only keep you engaged during the long, hot months but will also keep you physically fit and healthy. Those who are stuck with a few extra pounds can go swimming to tone their bodies up with lean, mean muscle as well. It is important that you wear the right kind of swimming gear for the activity - it is of utmost importance to protect your eyes with a pair of swimming goggles to ensure that they are protected from the harshness of chlorine that is bound to be in every single swimming pool. The treated water can cause allergic reactions apart from infections and even cause temporary blindness, all of which can be prevented by using a well-fitting pair of goggles. They also ensure that your eyesight underwater is crystal clear to allow you to see where you are going and give you cover from the harsh UV rays of the sun that you are more exposed to when you are in a swimming pool.
