What is EnChroma?

EnChroma is an independent Berkeley-based company that makes leading edge, patented lens technology and modern eyewear for color blindness.

There are an estimated 350 million people in the world with red-green color blindness, or about 4% of the total population. Due to red-green color blindness being acquired genetically from the X-chromosome, it affects mostly men. The condition affects: approximately 1 in 12 men (8%), but also includes about 1 in 200 women (0.5%). There are different types of Color Vision Deficiencies (CVD's) that are mostly genetic, along with some age-related color deficiencies.

Are you one of the estimated 350 million people that can only see approximately 10% of the colors? If so, call the office to schedule an appointment or click the Appointments link under the Patients tab. Expect the exam and experience to last a MINIMUM of 1 hour. We'll give you some time to walk around with lenses we find that should best work for you, to get a basic experience. Since no brain works the same, some patients may need extra time to adapt and experience some color difference. The longer you wear the eyewear, the more change you may notice. EnChroma isn’t a cure for color deficiency but a tool to enhance your color vision and will work for most but not all patients. After your exam, you'll be able to select loaner pairs of EnChroma Eyewear with non-Rx to utilize for up to 14 days at a rate of $125.00 per pair for your "try before you buy" period. If you return before the 15th day, as long as the loaner pair is in the same condition as it left, then we'll credit you $100.00 if they simply didn't work for you or for use towards a complete pair of EnChroma Eyewear!
