This website provides vision training assistance; it is not medical diagnosis and cannot replace an ophthalmologist's examination or prescription.

Whether training is appropriate, how long to train, and how to adjust should follow your ophthalmologist's or optometrist's advice.

If you experience headaches, eye pain, nausea, obvious diplopia, or vision loss during training, stop immediately and seek medical care.

To generate your training plan, this website stores your uploaded medical record photos, diagnosis information, vision data, and training records.

Medical record photos, diagnosis, and vision data are stored in encrypted form in the database and only decrypted by the server when you view them.
