Reduce Eye Drop Waste by 60% - Save Money on Expensive Medications
The only FDA-listed volume-reducing adaptor for eyedrop bottles. Simply twist on and get smaller, more efficient drops. Extend the life of eye medication.
- Clinically Proven
- HSA/FSA Eligible
- Reduced Side Effects

Eyedrops Are Too Big. Your pockets and eyes are paying for it.
Current eyedrop bottles dispense about five times the liquid your eye can absorb. Up to 80% of every drop is wasted due to overflow onto your cheek, or drainage by the tear ducts where the medication is absorbed into the rest of your body.
Decades of clinical research has shown that smaller drops are as effective, and in many cases, safer than current drops — yet you are still forced to pay for this wasted medication.
- Assemble in seconds
