Eye Black Grease — The Evidence


Does eye black grease work to reduce glare?  A 2003 Archives of Ophthalmology paper investigated this question by placing 46 subjects in the sun and testing their vision using a sensitivity contrast chart.  Each subject served as an internal control and then was randomized to either application of eye black grease, antiglare stickers, or petroleum jelly at the infraorbital rim (control).

The conclusion: eye black grease reduced glare and improved contrast sensitivity in conditions of sunlight exposure compared with both control and antiglare stickers.
