Lumigan Eye Drop (bimatoprost ophthalmic solution) is a synthetic prostamide analog with an ocular hypotensive activity regulating the flow of fluid within the eye to maintain a normal pressure used to treat certain types of glaucoma and other causes of high pressure inside the eye.
 
Lumigan is also used to improve the fullness, length, and color of the eyelashes in people with a condition called hypotrichosis, a lack of eyelash growth.
