Blepharitis is when you have bacteria and oily flakes at the base of your eyelashes. Your eyelids are red, swollen, or feel like they are burning. Blepharitis is very common, especially among people who have oily skin, dandruff or dry eyes.
Everyone has some bacteria on their skin. Some people, however, have more bacteria at the base of their eyelashes than other people. This can cause dandruff-like flakes to form. Also, some people have problems with oil glands in their eyelids, leading to blepharitis.
