Eye Comfort
The Only Eye Health Ingredient with a Completed Human Trial for Dry Eye
Dry eye affects 344M+ people globally.
That is one in four adults experiencing dry eye, driven by screen time, aging, and environmental factors. Yet most eye health ingredients address only one mechanism.
PCE-PRO is the only anthocyanin-based eye health ingredient with a completed human RCT for dry eye, showing 3 statistically significant outcomes. Preclinical research further supports its potential in eye strain relief and macular protection — extending its relevance across all three major eye health categories.
What the Trial Showed
In a randomized, placebo-controlled 12-week trial (500 mg/day), PCE-PRO demonstrated statistically significant improvement over placebo in OSDI, TBUT, and Corneal Fluorescein Staining.
Two additional measures — Visual Analog Scale (subjective discomfort) and Schirmer's test (tear volume) — showed a favorable trend but did not reach statistical significance in this trial.
