This eye dropper retainer is designed for those that need to take two types of eye drops, one in the AM and both in the PM. I place the eye drop containers in the holes marked either ODD or EVEN, based on the day of the month. On an Even Date, after taking the AM drops, the dropper is placed in the center hole. After taking both drops in the PM, both droppers are placed in the ODD day's holes.
Later on, I can check to see if my recollection of taking the pills is for today or yesterday, and act accordingly.
The author marked this model as their own original creation.
