Contact lenses came into use about a hundred years ago. They are alternates for eyeglasses. Unlike earlier, these lenses are now made from soft plastic rather than glass or hard plastic. You can apply or remove them on and off your cornea anytime. They are easy to use, however, they come with risks and require proper maintenance. When you wear contact lenses your eyes might get watery, you can see redness and feel discomfort in the eyes. To avoid them, do not rub your eyes vigorously, the lens can move from your cornea. And, do not go near the fire, plastic can melt in your eyes. Visit an optician who will refer to the best contact lenses and you can avoid any type of vision impairment.
