Using eye droppers need skills,for most of the times the drops fall somewhere other than the eye.The problem is that the person usually looks at the tip of the eye dropper with an inclined head and since the line of the drop fall is not the same to the line of sight,drops would fall outside of the eye.
Ezdrop is our proposed solution for this problem.A virtual nozzle(a target point)is placed below and parallel to the main nozzle and with the person looking at this fake nozzle instead drops will find their way into the eye.The good thing is that it's not a new eye dropper design but a low-cost additional part to your everyday eye-care product.
