Available options: Size 14, Size 15.
This is an eye drop dispensing adaptor. Fitted in place of the original cap, it reduces the volume of an oversized eye drop by over 60%. One adaptor is for one bottle: it should not be removed and reused on another bottle.
Size 14
The Nanodropper is an adaptor that replaces the cap on an eye drop bottle. This is Size 14, which refers to the metric measurement in millimetres of the eye drop bottle's neck. Size 14 was created to add coverage for an additional 7% of bottles beyond those the Size 15 fits. It arrives pre assembled, with a soft silicone tip, a bullseye pattern on the top face, a pop off cap and a flat anti roll base. It is a sterile Class I device listed with FDA.
Size 15
The Nanodropper is an adaptor that replaces the cap on an eye drop bottle. This is Size 15, which refers to the metric measurement in millimetres of the eye drop bottle's neck, and it fits the vast majority of standard eye drop bottles. It arrives pre assembled, with a soft silicone tip, a bullseye pattern on the top face, a pop off cap and a flat anti roll base. It is a sterile Class I device listed with FDA.

Nanodropprt
I love the nanodropper! It really works to give the one drop of medicine I need! I am so glad I was told about it because I was having trouble with waste.
Nanodropper
Works perfectly
Good product - lousy delivery
Like the product but as long as they rely on the incredibly unreliable US Postal Service we will not use them again.
Broke after one week
The base of the lid broke after using it for a week. I wish it worked out but I will not purchase again.
Eye drop
It’s ok but not the way advertised it , this product might reduce %30 not %60
Nanodropper Eye Drop Extender
Excellent, does not fall all over the place. With the extender it goes right into the eye. Happy I made the purchase. I was a little hesitant, not anymore.
Tiny drops—love it!
I use this on my Lumigan bottle and it works well. I typically get too much and it spreads over my cheeks. With this, the drop stays in my eye.
Did not work
This product did not fit on my Miebo eye drops bottle. I had to send it back. The idea is good, but the product did not work.
Results
After installing the dropper on my bottle, It was difficult to open and close the dropper. It's much better now. However, now it drops more than one drop out, sometimes hanging on or dripping down the side of the dropper when I put it right side up. Too bad I can't sterilize it to reuse again. It's rather expensive to have to have a new one for each bottle.
Poor fit
I have two 14's and one 15. When you take the top cap off, the whole thing falls off. Threads don't hold.
