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 bottle and discard at the end of the bottle-life. For more information on how many to order, click the button above.

We always recommend that you talk to your eyecare professional to ensure that Nanodropper is right for your treatment plan.

Tired of having expensive medications dripping down your face? Current eyedrops are 5 times too big for your eye meaning up to 80% of every drop is wasted.

The Nanodropper is the first and only adaptor for eyedrop bottles that reduces the drop volume by over 60%. Smaller drops have been shown to reduce waste, cost, and side effects of eyedrops.

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 size 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 some 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?

Our recommendation is always to follow the instructions included with your medication and to have a conversation with your eye doctor and follow their instructions. For general guidance, most preservative-containing eyedrop bottles are safe to use up to the printed expiration date on the bottle, as long as you follow the manufacturer's storage guidelines.

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.
