What this Trial Is About
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.
