Researchers at The OSU College of Optometry are seeking individuals who regularly wear eyeliner to investigate the impact on tear thickness.

Participants will be asked to attend two study visits of about one hour each. The participant’s vision and eye health will be evaluated at both study visits,  and non-invasive assessments of the tear film will occur as well. 

Participants will complete the study over approximately one week. Each visit should take no longer than one hour.
