Contact lenses are not quite safe. It can damage your eyes if you wear them too long, do not clean it properly or not replace them as directed by eyes specialist.
Keep the Oxygen flowing to Your Eyes. Contact lenses rest directly on the eyes and cover the entire cornea. They decrease the amount of oxygen that reaches your eyes from the environment. A good oxygen supply is essential to keeping your eyes healthy.
Contact lenses also increase the risk of eye damage because bacteria and other infection-causing agents can accumulate on them. This is especially true as the lenses get older and deposits accumulate on the front and back surfaces of the lenses.
