How do eyelash growth abnormalities affect the body?

In general, eyelash growth disorders only affect the eyes. The effect that an eyelash growth abnormality will have on your life depends on the cause and your symptoms. The conditions can lead to damaged corneas, cataracts, and eye cancers. Your vision may become blurred or clouded.

An extra set of eyelashes growing on the inner lining of the eyelid can cause your eyes to become irritated and bloodshot with subsequent irreparable damage. Conversely, excessive eyelashes may not really affect you that much and some people never experience distracting symptoms. Conditions that cause loss of eyelashes or very little growth may prevent you from spending time in the sun, as UV rays can damage your unprotected eyes and cause vision changes, cataracts and even blindness.

Loss of eyelashes can occur in certain rare congenital diseases. Much more commonly, eyelash loss can result from chronic infections of the eyelid margin by Staphylococcus bacteria in a condition called blepharitis. Conditions that cause loss of body and scalp hair, such as cancer chemotherapy or alopecia, also cause loss of eyelashes. Finally, eyelashes are sparse in many persons who have reached old age.
