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
- Triple the life of your bottle

I got this for Meibo after my first bottle was gone after 3 weeks. It works great with the Meibo. I get smaller drops that enables me to use bottle for a month plus. Haven't had any issues with the Nanodropper itself. My dry eyes are much happier. To me it is worth it since the Meibo itself isn't cheap.

Used Nanodropper for my most expensive eye drop that costs >$120. It has saved me a lot of money and eliminates so much waste. No more eye drop running down my cheeks!

This item works very well. The droplet size is a fourth to a third the size on the usual drop. My eyedrops have increased in price to over $100 a bottle due to manufacturer greed and this dropper system will help me afford my medication.

I use on Vuity and Meibo...bottles now last twice as long which is great since these aren’t cheap or covered by insurance.

Used by Doctors
"I have many glaucoma patients on branded medications that are effective at managing their glaucoma. Many of these patients are on fixed incomes and depending on coverage they sometimes cannot afford them. With many of these branded medications there is no generic formulation, so I have no substitute for these effective medications."
Justin Schweitzer, OD
“With Nanodropper you still get the same effectiveness of your eyedrop, you are just reducing the waste by up to 70 percent.”

How do I know which size I need?
We have 2 sizes that fit the vast majority of bottles. Check our compatibility list before purchasing to ensure you get the correct size for your bottle.
What's the difference between Size 15 and Size 14?
Size 15 and 14 come from the metric measurement (in millimeters) of your eyedrop bottle's neck, right where the original cap twists on.
Our Size 15 (the original Nanodropper size) fits the vast majority of standard eyedrop bottles. We created Size 14 to add coverage for additional 7% of bottles.
