Post Market Clinical Study to Compare Vision With Essilor® AVA™ Lenses Following AVA™ Refraction Protocol to Equivalent Lenses Following Gold Standard Refraction Protocol.
Essilor International
Summary
The goal of this clinical trial is to assess improvements in visual performance and patient outcomes in wearing new spectacle lenses in general population. The two spectacle lenses will be compared after two weeks of wearing. The aims are: * to evaluate the visual superiority, and quality-of-life implications of Essilor® AVA™ spectacle lenses prescribed after a new subjective refraction protocol named AVA™ protocol. * to understand the benefits of using a high accuracy instrument and testing sequence over the standard testing sequence in determining a glasses prescription, as well as the overall subjective performance of the resulting glasses.
Description
This study aims to evaluate whether finer increments in refraction and spectacle lens manufacturing (0.01D) provide more precise visual corrections compared to the traditional 0.25D steps, and if participants can visually appreciate this difference in the refractive outcome and manufactured lenses. It will assess improvements in visual acuity, comfort, and patient satisfaction, focusing on achieving red-green equality in the duo chrome test and exploring the clinical utility of higher resolution refraction technologies. Refraction is a critical procedure in eye care that determines the optima…
