Neurolens and Contact Lens Discomfort

Southern California College of Optometry at Marshall B. Ketchum University·interventional·Posted Apr 6, 2023·Updated Apr 22, 2025

In Brief

A clinical study evaluating Neurolens and Placebo spectacle lens for Contact Lens Discomfort. Completed, enrolled 30 participants across 1 site.

Detailed Summary

The objective of this study is to determine how neurolens® influences contact lens discomfort in uncomfortable myopic soft contact lenses wearers. It is hypothesized that uncomfortable soft contact lens wearers are experiencing some level of discomfort associated with increased vergence demand when looking at near targets and will experience discomfort relief when wearing neurolens® over their habitual soft contact lenses. Uncomfortable, myopic soft contact lens wearers will be recruited. Each participant will be masked and randomly assigned a placebo pair of spectacles or a neurolens® spectacle pair for approximately one month. A prospective, randomized clinical trial will be performed. Participants and investigators will be masked to the treatment.

Interventions

Neurolensdevice

neurolens® is a type of spectacle lens that uses contoured prism to alleviate vergence demands and fatigue at near and, therefore, encourages comfortable vision.8 This spectacle design uses the neurolens® Measurement Device (nMD) to measure eye alignment and determine the spectacle lenses that are uniquely designed for each wearer.

Plano (no power) spectacle lenses will be assigned to the placebo group
