Missing your own eye with a drop is common enough that a small product category exists to solve it. Magic Touch is that product here: one applicator that holds a standard dropper bottle and positions it over the eye for you.
The bottle seats in the applicator, and the applicator rests against the brow and cheek, so the tip arrives already aligned and at a fixed distance. There is no tipping your head back, no aiming by feel, and no holding a small bottle steady at arm's length. The design came from ophthalmologist Dr. Julius Shulman, and the body is made with silver ions.
Three groups, mostly. People with tremor or reduced grip strength, for whom holding a bottle steady is the hard part. People using a preservative free drop from counted vials or a counted bottle, where a drop that lands on a cheek is a drop that is gone. And people who flinch as the drop falls, which is involuntary and does not get better with practice.
Check the bottle you already use. The applicator is built around standard dropper bottles, so a single use vial or a squeeze tube is a different shape and will not seat the same way. Optase also sells its Intense drops bundled with a Magic Touch applicator, which is worth comparing if that is the drop you buy anyway.
Beyond that there is only one version, so the decision is simple: either aiming is a problem you have, or it is not. If you are struggling to get drops in at all, mention it at your next appointment, because there are other ways to approach it too.
