<p>An eyedrop dispenser (10) uses the natural optical lens effect to a transparent droplet (36) formed at the tip of the dispenser to focus the image of a target (28, 33) disposed inside the outlet (16) of the dispenser. The target image is viewable by the use to align the droplet with the eye (74) 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 (33) located inside the dispenser on the image plane (34) 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 (33) through which the liquid contents pass prior to dispensing.</p> |
