My HYLO eyedrops are dispensed by Pump Action; it doesn't need squeezing or gravity.
I usually must instill eyedrops myself; nobody can help me. But I miss too often.
Method 1: Vertical drop in eyes, while staring at the ceiling and lying on my back.
1.1. I wash my hands.
1.2. I lie flat on my back (on the couch or ground). I then stare at the dispenser's opening.
1.3. My right eye (OS) is dominant. So I instill left eye first (OD), while keeping open OS:
1.4. After closing both eyes for 5 mins, I keep OS open when instilling OD.
1.5. Difficulty: The drop lands on an eyelash, or the Upper or Lower Eyelid.
Method 2: Squirt in eyes, while standing and in front of mirror.
2.1. I stand in front of a mirror to witness my aim.
2.2. Same as 1.3. I aim the dispenser at the caruncle:
2.3. Difficulty: Because I'm standing, most of the drop falls out the eye.
