SKU: SQ1255813 Category:

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.

The Nanodropper was designed to improve every aspect of the eyedrop experience. See more information on product features and usability here.

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?
The Nanodropper adaptor is a sterile medical device and is not intended to be taken off the bottle once installed. We recommend using one adaptor per medication to prevent risk of contamination, infection, and injury.
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?
Expiration of medications is a tricky science. Our recommendation is always to have a conversation with your eye doctor and follow their instructions. For general guidance, the American Academy of Ophthalmology recommends that you throw away your bottle of eyedrops 3 months after you open the bottle.

See all FAQs here.

Use one Nanodropper per bottle. Do not transfer or reuse on subsequent bottles. Misuse, reuse, or attempts to re-sterilize Nanodropper may result in reduced treatment efficacy, serious infection, injury, or death. Dispose of your bottle when recommended by your eyecare professional. Nanodropper may not be used with some treatment plans, always consult your eyecare professional before using the Nanodropper.

    I bought my Nanodropper from my ophthalmologist’s office. It was $21.00 there, so more expensive but no shipping costs. Also, it does not work on all bottles, as stated in the literature. I specifically bought it for a particularly burning medication so I would not have extra medication and more burning than necessary. It works but is clumsy since it does not fit the bottle. Still, I will continue to buy these to lower the expense of the medication. I am going to order a few more off the web site to have them available and to use on my other prescription eye drops. I would like if they could attach the blue nipple to any bottle and just stay put without the securing ring, which is the part that does not fit. Then maybe be able to use the original cap as well, and lower the cost of the device in the process.
