What is blepharitis?

Blepharitis is an infection of the eyelids and eyelash follicles and is due to bacteria called Staphylococcus or sometimes parasitic mites called Demodex. It is the commonest cause of red, scratchy, dry eyes and eye specialists see it all the time. You will not know what the cause of your red, scratchy, dry eyes is until you have been examined by an eye specialist or optometrist at a slit lamp (microscope). 30% or more of children and adults suffer from Blepharitis! 66% of elderly people suffer from blepharitis. This is huge! Blepharitis is so often undiagnosed because it causes the same symptoms as dry eye and allergies. Patients will often talk about “scratchy eyes, dry eyes, heavy/tired and sore eyes, sensitive eyes,” but there is underlying blepharitis causing those symptoms. Also dry eye, allergies + blepharitis are often part of a triad called ocular surface disease .All 3 conditions need addressing in order to alleviate the problem.
