What is blepharitis?

Blepharitis is a common eyelid inflammation with a complex set of causes. It is also commonly called lid margin disease because it affects only the edges of your eyelids. It can happen either when certain skin conditions cause irritation or when bacteria results in infection, or a combination.

As a result, your eyelids may become red, swollen and scaly. Blepharitis usually affects both eyes. In some cases it can only affect one eye, but this is uncommon. Once blepharitis occurs, it’s possible to also get a secondary infection. Though uncomfortable, most cases aren’t contagious and won’t cause blindness.
