## Description

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.
