NovaVision, Inc., headquartered in Boca Raton, Fla., researches, develops and provides scientifically based, innovative medical technologies to restore the vision of patients with neurological visual loss.

NovaVision's VRT devices map areas where vision may be improved and then provide neurostimulation to the appropriate region within the brain's vision-processing areas. Once only available at select medical centers, VRT can now be prescribed by any neurologist, neuro-ophthalmologist, ophthalmologist, optometrist, physiatrists and continues to be recommended by leading neurological, eye and rehab centers nationwide.
