Abstract: A novel applicator for engagement to an eye drop vial. The eye drop vial would be squeezable and contain a liquid therein that is compatible with the eye. The adapter includes a neck having a multiplicity of inner diameters adapted to a multiplicity of eye drop vials and a cup. The cup is semi-spherical shaped and has a rim that is collapsible between a closed position, which would seal off the vial, and an open position which would allow application of liquid from the vial to the eye of a user.
