    Abstract: An ophthalmic device for dispensing of an eyedrop from a resilient eyedrop dispenser. The ophthalmic device has an upper body portion having a front portion, first and second lever arm members rigidly connected to the front portion and extending in a longitudinal direction therefrom with distal ends of the arm members being spaced apart. An opening in the upper body portion for receiving the eyedrop container with outlet pointing down. Squeezing the arm members together reduces the opening thereby dispensing an eyedrop. An alignment projection is attached to the upper body portion and has a lower distal end for resting on an user facial area, thereby facilitating maintaining the outlet of the eyedropper container in alignment with a recipient eye. Sighting apertures are also provide to further insure proper alignment over the eye. The ophthalmic device has a shape effective for producing by injection molding.
