Our Clinical Study

Sightsage is undergoing a clinical trial to quantify the positive effects of our Blueberry Gummies on Dry Eye Disease.


  • University-led
  • Interventional Study
  • Randomized
  • Placebo-Controlled
  • Double-Blind
  • 60 Participants Ages 18+
  • 4 Weeks

We partnered up with the School of Optometry and Vision Science at the University of Waterloo, named the 5th best optometry school in the world, 3rd in North America and 1st in Canada by The Clinical and Experimental Optometry Medical Journal.

Our study titled "The Effect of a Novel Blueberry Supplement on Dry Eye Disease (PLUM)" was designed to demonstrate the therapeutic effect of our Blueberry Gummies on Dry Eye Disease. Dry Eye Disease will be measured with the change in OSDI scores from baseline and change in Non-Invasive Tear Break-Up Time (NITBUT).

If you’d like to take the same Dry Eye Disease OSDI test that is being applied to our Clinical Trial subjects, head to this link: www.sightsage.com/osdi

The completion of this study will mark a revolutionary step toward the caring of dry eye disease using evidence-based products rooted in Nutrition Science and Traditional Chinese Medicine.

Our study is estimated to be completed on November 30th, 2022 - stay tuned!
