10 Causes of Blepharitis
Cause #3: Parasites
A parasitic infection may also be a cause of blepharitis. The two most common parasites involved are known as Demodex brevis and Demodex follicular. These parasites can be found in hair or on the eyelashes, thereby making it easy for them to gain access to the eye organ. In the developed world, this type of infection is very rare, as it occurs in extreme unhygienic environments.
Washing the face, hands and contact lenses (for those who wear them) in normal frequency is enough to prevent this parasite from affecting your eye. This type of infection needs to be treated as quickly as possible. It is therefore important to check any eye infection, as what may appear as harmless may be blepharitis caused by a parasite.
