Eyes are incredibly complicated and very delicate. Modern lifestyle puts a real strain on your eyes.
Sports such as basketball, rugby, and football can easily throw up dirt and grit into your eyes, so while it may not be practical to wear eye protection, be aware of the possible dangers when playing these sports.
Also if you spend time swimming, the chlorine used in public swimming pools can make the eyes sting, making them sore. A pair of swimming goggles helps to protect your eyes against over-exposure to this harsh chemical – as such it is advisable not to swim in contact lenses.
Eye protection against everything the modern world can throw in your eyes is important for good eye health and vision.
