  • Patent number: 5584823
    Abstract: There is provided a new and useful device to facilitate the dispensing of eye drops from a conventional translucent or transparent eye dropper bottle which has a drop-dispensing tip at one end, a bottom at the other end and resilient, squeezable sides between those ends to dispel the bottle contents. The device combines a light source and a holder to hold the eye dropper bottle in place relative to the light source so that light from the source will pass through the bottom of the bottle, when in use, to illuminate a droplet of the contents of the bottle being dispensed from the tip.
