Did you know there is now a non-invasive treatment for color blindness? HOW IT Works: ChromaGen is a patented and FDA-cleared system of colored filters that alter the wavelength of light going into one or both eyes in a dynamically balanced format, which enhances color perception and discrimination. ChromoGen is available in both contact lenses and eyeglasses. THE PROCESS: The ChromaGen testing process is simple. The effect of ChromoGen is instantaneous, so you will know immediately if the lenses will work for you and there are no side effects for the user. Now ChromaGen users can now experience the vibrancy of traffic lights and occupational drawings to dramatic sunsets or spring flowers in bloom like never before.
