Summary

This clinical trial investigates the differences between three different progressive addition lens designs. It is a non-invasive double-masked randomized clinical investigation. For this study, 80 participants will be recruited.

Detailed description

The purpose of the study is to evaluate the preference, adaptability, and visual performance of three progressive lens designs. The difference in these lens designs is a variation of zone sizes for intermediate and near vision. The clinical trial helps manufacturers and eye care practitioners to give detailed suggestions to patients. Study participants will be experienced progressive addition lens wearers, which will be recruited by advertisements, by email, and with direct person-to-person solicitation. The study will be conducted at the Eye Care Institute at the Patient Care Center Western University of Health Sciences, Pomona, CA, 91766. For each participant, the study is completed in around two months and requires three separate visits.
