Analysis of existing fake-tear applicators yielded a clear design goal: to improve the dropper’s accuracy into the eye. This is the most basic and most important task of the dropper, and yet it is an incredibly difficult task to accomplish. For those with stable and capable hand function, aiming the drops can be difficult. In users with difficulty of sight and dexterity, this issue is further amplified. Most users tackle a free-hand approach, holding the dropper above the eye while the other hand pulls back the eyelids. This is mostly ineffective, especially for new users. It results in waste, mess, and undesired negative emotions experienced on behalf of the user. No user should feel ashamed or incapable over a simple design flaw. My goal was to address these pain points.
This product relies on the bridge of the nose to achieve accuracy. The user uncaps and locks the existing applicator into the product’s connection port. The user holds the end of the device and places the ‘U’ end on the bridge of their nose. The user’s other hand adjusts the connection port such that the dropper is directly above the eye (this can be done most accurately with a mirror). The user squeezes the applicator to apply the prescribed amount of fluid, then flips the device for use in the other eye. In basic user testing, the device was almost entirely accurate as compared to a very inaccurate 'free hand' approach.
