Study Summary
This is a Phase I, single center, open-label study of the dietary supplement calcium formate in normal, healthy female subjects. The purpose of the study is to determine whether daily use of calcium formate is safe and whether it accumulates in the eye.
Primary Outcome
Participants will be refracted at baseline and the resultant lens correction will be used for testing visual acuity at all subsequent visits. If a participant's visual acuity drops 10 letters or more at any visit, the participant will be re-refracted and the visual acuity will be tested again with the new lens correction in place.
