Rain Eye Drops LLC has introduced a meaningful innovation in eye care with the launch of the RainDrop Dispenser Aid, the first-ever tool designed to improve the application of single-use, preservative-free eye drops. Originally developed within the U.S. Department of Veterans Affairs (VA) by ophthalmologist Dr. Julie Schallhorn, the device addresses a widespread issue—difficulty in using monodose vials, especially among individuals with limited hand strength, tremors, or arthritis. Through an exclusive license from the VA and the University of California, Rain refined the patented technology for commercial use, combining medical ingenuity with user-centered design to enhance the everyday eye care experience.

The RainDrop Dispenser Aid significantly improves the usability of preservative-free eye drops by offering better grip, easier squeezing, and more accurate targeting. Its ergonomic design reduces hand strain and eliminates the frustration of missed doses or wasted medication—problems commonly reported by users of monodose vials. Importantly, it makes high-quality, preservative-free eye care accessible to a broader audience, including the elderly and individuals with physical limitations. With an increasing shift toward preservative-free formulations for long-term ocular health, tools like this dispenser are essential for enabling consistent and effective treatment.
