As I said earlier, our eyes blink and cycle through tears. When you blink, water, oil, and other substances, such as proteins, come out of the tear glands and form a protective layer on the skin of your eyes. The barrier prevents dry eyes and keeps them moist. But there are people who don’t have this capability. When you use contact lenses, people who lack these features easily feel uncomfortable when they are full of eyes or when they use contact lenses. Therefore, you should meet your eye doctor or optician to test your contact lenses to see if they are suitable for you and to get a prescription for your contact lenses.
