    There are three main types of blepharitis:staphylococcal blepharitis, Blepharitis is an inflammation of the eyelids. It usually affects the edges (margins) of the eyelids. It is not usually serious seborrhoeic blepharitis, Seborrhoeic blepharitis is closely associated with a skin condition called seborrhoeic dermatitis. In seborrhoeic dermatitis, the affected skin becomes more oily and can become scaly. Seborrhoeic dermatitis typically causes bad dandruff and sometimes a rash, commonly on the face and upper body and meibomian blepharitis. People with meibomian blepharitis are thought to have a slight problem with their meibomian glands and the fluid they produce. This may lead to eyelid inflammation. This also explains why people with meibomian blepharitis often have dry eyes as the fluid they make may not be adequate to lubricate the eye.all three types can cause similar symptoms.

    Everyone has bacteria on the surface of their skin, but in some people,bacteria thrive in the skin at the base of the eyelashes.large Amounts of bacteria around the eyelashes can cause dandruff-like scales and particles to form along the lashes and eyelid margins. Other diseases and conditions that can cause blepharitis may include: Malfunctioning of the meibomian eyelid oil glands Seborrheic dermatitis(dandruff of the scalp and eyebrows) Acne rosacea(a skin condition that causes redness of the face) Eyelash mites(tiny organisms in the eyelash follicles) Allergic reactions to cosmetics or medications
