Study Summary

This trial shows that color-correcting lenses improve color vision in people with deficiencies.

Who is the study for?
This trial is for individuals with hereditary color vision deficiencies (CVDs) who have normal eye health and a visual acuity of at least 20/30. It's also open to those with normal color vision as controls. People using sleep or wakefulness drugs, or those with eye diseases are excluded.Check my eligibility
What is being tested?
The study tests if wearing color-correcting lenses can improve the color vision in people with CVDs. Participants will be split into groups; some start with placebo lenses then switch to color-correcting ones, while others do the opposite.See study design
What are the potential side effects?
Since this trial involves non-invasive lenses similar to regular contact lenses, side effects may include discomfort while wearing them, potential eye irritation or strain.

Trial Design

5Treatment groups
Experimental Treatment
Active Control
Placebo Group
Group I: Crossover: Placebo to ExperimentalExperimental Treatment1 Intervention
Placebo Group 1 crosses over to become Experimental Group 2 which includes baseline testing with and without color correcting lenses, followed by 7 days of wear, minimum 3 hours/day, followed by retesting with and without color correcting lenses.
Group II: Color Vision Deficient with Color Correcting LensesExperimental Treatment1 Intervention
10 subjects confirmed to have hereditary color vision deficiency randomly assigned to experimental group 1 which includes baseline testing with and without color correcting lenses, followed by 7 days of wear, minimum 3 hours/day, followed by retesting with and without color correcting lenses.
Group III: Control Group: Subjects with Normal Color VisionActive Control1 Intervention
Fifteen subjects confirmed to have normal color vision will be tested in a single session to determine whether color correcting lenses affect color vision in color vision normal subjects and to provided normative data for several unique measures of color vision performance
Group IV: Crossover: Experimental to PlaceboPlacebo Group1 Intervention
Experimental Group 1 crosses over to become Placebo Group 2 which includes baseline testing with and without placebo lenses, followed by 7 days of wear, minimum 3 hours/day, followed by retesting with and without placebo lenses.
Group V: Color Vision Deficient with Placebo LensesPlacebo Group1 Intervention
10 subjects confirmed to have hereditary color vision deficiency randomly assigned to Placebo Group 1 which includes baseline testing with and without placebo lenses, followed by 7 days of wear, minimum 3 hours/day, followed by retesting with and without placebo lenses.
