Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
