Hand tremors and reduced grip strength can make aligning and squeezing a conventional eyedrop bottle difficult without assistance.

Eyedrop
Dispenser
Five concepts for a reusable, button-operated eyedrop dispenser designed for people with hand tremors, limited grip strength, or less experience applying drops.
Enable stable, one-handed dispensing so the other hand remains free to hold the eye open when needed.
Concept 01 moves forward from five form studies, combining a compact grip, push-button intent, and a side-of-nose positioning reference.
Human Context
The project began with a loss of independence
This project began with someone close to me: a water polo player who experiences hand tremors. He is usually able to manage his daily routine independently, but after demanding practices, fatigue makes it difficult to steady, align, and squeeze a traditional eyedrop bottle. At times, he has to rely on his sister to administer the drops.
His experience revealed that the challenge extends beyond tremors alone. Reduced grip strength, fatigue, and limited familiarity with eyedrops can turn a simple routine into a task that requires assistance.
The opportunity was not simply easier squeezing—it was a more stable, confident way to self-administer.
Market Gap
Most existing aids still require squeezing
Market research showed that many existing aids clip onto disposable eyedrop bottles. While they may help with positioning, users still have to squeeze the original package.
That creates two missed opportunities: the aid is tied to a disposable bottle, and the primary grip action remains unchanged.
01Integrated reusable vessel instead of a disposable add-on
02Push-button dispensing instead of forceful squeezing
03Face contact that guides alignment above either eye
Independent use shaped every concept
Operate the dispenser with one hand so the other can hold the eyelid open.
Replace squeezing with a clear, easy-to-press button mechanism.
Use the nose or surrounding face as a repeatable positioning reference.
Create a compact refillable form that works for both eyes and everyday users.

Five Directions
Comparing five approaches to alignment and grip
The final set tests different relationships between the hand, nose, eye, and button. Each direction supports one-handed use while varying how the product is held, rested, rotated, and carried.
Concept 01 moves forward
I selected Concept 01 because its compact shape is easy to carry and feels comfortable to hold. Resting against the side of the nose offers a positioning reference with the potential to accommodate different face shapes. That adaptability remains a hypothesis to check with users.
Next user check: Ask the water polo player who inspired the project to hold and position the foam models without dispensing liquid. Compare grip comfort, button reach, contact with the side of the nose, and alignment for both eyes. Record feedback before refining Concept 01.
