Abstract
An eyedrop dispenser uses the natural optical lens effect of a transparent droplet formed at the tip of the dispenser to focus the image of a target disposed inside the outlet of the dispenser. The target image is viewable by the user to align the droplet with the eye when dispensing eyedrops or other liquid medication. The target image is arranged so it comes into focus just prior to when the droplet being formed at the tip of the dispenser is ready to be released from the dispenser tip. The target image is formed by an image plane indicator device located inside the dispenser on the image plane of the droplet when the user is viewing the indicator through the natural transparent lens formed by the droplet. The indicator can be a pinhole through which the liquid contents pass prior to dispensing. The pinhole is focused by the lens and formed as a magnified image by the lens effect of the droplet. Other target-forming indicators can be positioned at or near the image plane to form enlarged optical images of targets useful for the accurate dispensing of the liquid contents.
