There are three reasons why some people can't wear contact lenses. First, people who have sensitivities to the material of contact lenses can't wear contact lenses. When their eyes are allergic to the material, they will feel uncomfortable. Second, if people's eyes are too flat or too round, there may be not suitable contact lenses for them too. The shapes of their cornea don't match with the contact lenses. Third, if people who just have surgery on their eyes, it is better for them not to wear contact lenses as well. Wearing contact lenses can make their eyes drier and get more chances to get eye infection.
Nowadays, there are more and more people wear contact lenses. Do you know that not all people can wear contact lenses. Here are 4 situations that can't wear.
