Optokinetic Nystagmus Testing

Features & Capabilities

OKN Strips is a diagnostic and therapeutic eye-test app that uses optokinetic nystagmus (OKN) testing to assist neurological, otological, and ophthalmological evaluations.

The app offers interactive controls: tap to cycle strip speeds, toggle colors between Red and Black, pinch to adjust strip width, and swipe to reverse direction. A two-finger tap hides or shows the bottom toolbar, while icons on the bottom toolbar provide quick access to Red Desaturation and Amsler Grid tests.

Should have a recording feature

I like it!

My vision therapist recommended this app to help with eye stretches. It’s good, but I wish I could change the direction the bars move. I have to do this exercise with a patch on because my eyes don’t track together. So I’d like it if the bars could travel left or right and up or down.
