Why Do My Eyes Itch?

Allergie

- most obvious answer, but not necessarily most common

- signs: swollen/puffy eyelids, watery eyes, bumps under eyelids (seen by your doctor), diffuse and more intense itch

 

Blepharitis (blepharo- = eyelids, -itis= inflammation)

- so, inflammation/irritation of eyelids, very common

- could be due to mild bacterial infection or blockage of glands at the base of eyelashes

- signs: redness along eyelid margin, itchiness usually concentrated at eyelid margin or at the corners of your eyes but not as intense as with allergies, also watery eyes
