Phthiriasis palpebrarum caused by the parasite Pthirus pubis, is an uncommon cause of blepharitis under unhygienic conditions in sexually active adults. It is often misdiagnosed as bacterial, viral, allergic conjunctivitis or seborrheic blepharo-conjunctivitis.  A 35-years-old man presented with itching & irritation over eyelids. On examination, multiple translucent oval nits and lice adhering to the eyelashes were found. In this case report we want to emphasize on the rarity of this case and that commonly available petroleum jelly and 1% permethrin shampoo used together are simple, cheap, safe, and effective treatment to combat Phthiriasis palpebrarum. Also, patient education regarding hygiene is of paramount importance whenever phthiriasis is encountered.
