an eyedrop adapter on a mission to reduce barriers

Who we are

The Nanodropper is an affordable, universal eyedropper adaptor that decreases the volume of the currently oversized drops to reduce cost, waste, and side effects,
ultimately increasing access to expensive prescription eye medications.

Current packaging of prescription eyedrop medications administers drops up to five times greater than the capacity of the human eye. Thus, eyedrop application results in wasted overflow onto the user’s face, or drainage by the tear ducts. Consequently, many patients encounter bottle exhaustion, where their eyedrop medication runs out before the end of the month. This forces patients to choose between paying out-of-pocket for medicine or not complying with their prescription.

This problem is particularly distressing for low-income patients battling diseases like glaucoma, a leading cause of blindness in the United States and abroad. On average, a bottle of prescription eyedrop medicine costs $350 out-of-pocket, and missing applications can threaten patients' vision. This problem also extends to all patients prescribed expensive eyedrops such as patients with acute corneal injury, chronic dry eye, and post-cataract surgery.

Clinical research demonstrates that smaller eyedrops are just as efficacious as larger eye drops. However, drug companies have resisted reducing drop size, likely because of the negative impact it would have on their revenue streams.

With our primary focus on providing an affordable solution to a global problem, we are empowering patients to regain control of their health care.

Health benefits of smaller droplets

Decreased side effects

Overdosing can cause adverse side effects that range from minor annoyances such as foul taste and smudging makeup to serious systemic effects on heart health such as causing bradycardia and arrhythmias.


decreased rate of adverse events in the elderly

"Glaucoma patients who go untreated... run the risk of worsening vision loss and increased likelihood of requiring surgical intervention... Vision loss from glaucoma has been associated with an increase in the rates of falls, depression... reduced physical activity, and nursing home admissions." -American Glaucoma Society

improved efficacy

Clinical studies demonstrate that smaller eye drops are just as efficacious as traditional droplets. Studies have also shown that larger droplets irritate the eye, eliciting a tearing, blink, and drain reflex that dilutes the medicine. By alleviating this reflex, smaller droplets deliver a more potent medication dose.

limited preservative exposure

Eyedrop medications contain preservatives that ensure the sterility of the contents of the bottle. Reducing droplet size will minimize patient exposure to these potentially toxic preservatives.


higher adherence

By reducing many of the top complaints arising from oversized drops and minimizing the adverse side-effects, the Nanodropper is removing multiple barriers to patient compliance. We hope to help maintain productive doctor-patient relationships and promote eye health by making consistent treatment a pragmatic long-term option for our customers.
