Tired of having expensive medications dripping down your face? Current eyedrops are 5 times too big for your eye meaning 80% of every drop is wasted.
The Nanodropper is the first and only adaptor for eyedrop bottles that reduces the drop volume to just what the eye can absorb. Smaller drops reduce waste and unwanted side effects of eyedrop medications.
Follow these steps to ensure the Nanodropper is right for your drops.

What is the right dose for eyedrops?
Multiple studies support that 7-10 microliters is the ideal-sized drop size for the average human eye. Typical eyedrop bottles administer upwards of 50 microliters. The Nanodropper adaptor reduces the size of each drop the ideal 10 microliter range.
Why are smaller eyedrops safer?
There’s a limited space on your eye that can hold extra liquid. After that limit is met, the excess will be drained by your tear ducts or blinked out of your eye. The bigger the initial drop, the bigger your eye’s response to the foreign sensation. This means more medication is absorbed into your body, instead of just in your eye as intended by your doctor. This can have what is called “systemic side effects,” where the medication acts as if it was administered through an IV. Because the severity is volume-dependent, the smaller drops have been shown in clinical studies to be safer.
I use 2 medications, can I share one Nanodropper for both bottles?
Can I clean and reuse the Nanodropper adaptor?
The Nanodropper adaptor is a sterile medical device and is not intended to be taken off the bottle once installed. Please use one adaptor per medication bottle and discard at the end of the bottle-life. Home sterilization has not been studied with the adaptor, and can lead to contamination, infection, and injury. Do not attempt to clean or reuse any parts of the Nanodropper adaptor.
When should I throw away the bottle of eyedrops?
