ABSTRACT:
BACKGROUND
The proper application of opthalmic solutions using an eye dropper or dropper bottle is problematic for many individuals. It is difficult for an individual to properly align the tip of the dropper with their eye. This problem is frequently compounded by poor vision.
There have been many attempts to resolve this issue. It has been suggested to provide a target ring for an eye dropper in U.S. Pat. No. 4,629,456. Other references have suggested illuminating the eye dropper tip using for example a flashlight as disclosed in U.S. Pat. No. 5,584,823. Merely changing the color or providing a target for the tip of an eye dropper is relatively ineffectual. Using a flashlight to illuminate the tip of an eye dropper is cumbersome and expensive. Others have incorporated illuminating devices into the eye droppers themselves such as disclosed in U.S. Pat. No. 5,558,653 but these are expensive and increase the size of the dropper bottle.
SUMMARY OF THE INVENTION
Accordingly it is the object of the present invention to provide an eye dropper with an illuminated tip. Further, it is an object of the present invention to provide one without a separate attached light source. These objects are achieved by incorporating a light collecting or convex lens in the base or bottom wall of the eye dropper. When the eye dropper is raised toward the eye, the bottom side is pointed towards a light source either natural or man-made such as a window or overhead light. Light will pass through the lens and be focused on the tip of the eye dropper illuminating the tip. This provides an effective, inexpensive method to facilitate application of opthalmic solutions.
This invention will be further appreciated in light of the following detail and description and drawings in which:
