Abstract
The present invention uses an adaptation of a float valve installed within the barrel of the eye dropper at the time of manufacture. This prevents the operator of the eye dropper from intaking more than the predetermined amount of liquid into the barrel of the eye dropper. Once the eye dropper is filled, the operator expels the entire amount of liquid taken into the eye dropper, which is the predetermined amount.
