— ENTERTAINMENT ONLY —
This app is NOT a medical device. It does NOT provide any diagnosis, screening, or assessment of vision, color perception, or eye health. Results are simple game scores and are not a substitute for an eye exam by a qualified professional. If you have any concern about your vision, please consult a licensed ophthalmologist.
