The RainDrop Dispenser aid developed under exclusive rights from the U.S. Department of Veterans Affairs

(PRUnderground) July 9th, 2025

Rain Eye Drops LLC, a leader in preservative-free eye care solutions, has announced the launch of the RainDrop Dispenser Aid, a newly refined device exclusively licensed from the U.S. Department of Veterans Affairs (VA). This patent-pending tool is designed to help Americans with dry eye apply monodose eyedrop vials more easily and accurately—now available free with any Rain purchase.

If you scan the product reviews of single-use eye drops across online retailers, a common frustration appears repeatedly: people love the cleaner formulas but hate the packaging. Hard-to-squeeze vials, poor aiming, and wasted drops are among the top complaints. The RainDrop Dispenser Aid was created to directly address these issues.

Rain Eye Drops refined the device in-house and with manufacturers after exclusively licensing the patent-pending technology from the U.S. Department of Veterans Affairs and the University of California, to bring this concept to the market. The mission of the VA Technology Transfer Program is to improve Veterans’ lives by making better healthcare products and services available to them, with benefits to the American public as well. Originally invented by  Julie Schallhorn, MD, MS an ophthalmologist at SF VA to help veterans who struggled to use single-use vials, the device tackles the frustration of fumbled applications, squeezing too hard, or wasting precious drops. Arthritis, shaky hands, or just the daily hassle—this tool was made to end it.  Schallhorn noticed a common struggle among her patients, especially those with limited hand strength and dexterity: applying eye drops.   “It’s difficult to see patients who are suffering and are not served by the current options, said Schallhorn.  “This was a major motivation for me.” 

“The ability to connect VA researchers and clinicians with top notch biomedical engineers in TTP’s TTAP helps the VA innovators translate their dreams into real world products that help Veterans and population at large,” said Dr. John Kaplan, TTP Director. “The overall process of development was quite smooth with the innovation lab, and working with the Tech Transfer office made it quite easy,” said Schallhorn.

“Rain is proud to bring this VA-developed technology to the public under exclusive license. It’s a game-changer for anyone who struggles with monodose eye drops,  whether due to arthritis, tremors, or the everyday hassle of aiming those tiny vials,” said Mike Rain CEO of Rain Eye Drops LLC.

Experts at Rain Eye Drops helped refine the tool’s design to provide users with: Better control – No more shaky, messy applications, Easier squeezing – Makes it simple to get every drop out. Access to the cleanest, preservative-free formulas – Many of the safest eye drops come in monodose vials. In an effort to make this device available to as many people as possible, Rain is now including the RainDrop Dispenser Aid for free with
any Rain Eye Drops purchase. Part of Rain’s mission to make dry eye relief easier and healthier for everyone.
