What is ColorView?
ColorView® Lenses are designed to help distinguish colours easier. Regular eyeglasses help focus images, ColorView® glasses help focus light!
Many people we have talked to with colour vision deficiency have symptoms that keep them from seeing the colour red well. Instead they perceive to see more green causing their view of colours to be distorted. If you have or know someone who has these symptoms then ColorView® may be right for you.
Human eyes can see many colours, however the eyes can only perceive three prime colours of light. ColorView lenses adjust the amount of each of the Three Prime Colours (Red,Green,Blue) entering your eye. Colours made of a combination of the Three Prime Colours of Light can be distinguished easier if perception of each colours is adjusted properly.However, there are differences among individuals perceive a colour even though the wavelength of the light maybe the same.
So if the Three Prime Colours of Light are not perceived properly, some colours that are combinations these three colours may become difficult to recognize. This is considered to be the cause of genetic colour vision deficiency. By adjusting and altering the three prime colours of light entering eyes it becomes easier to distinguish colours. There are differences however among individuals perception of a colour even though the wavelength of the light may be the same.

How does it work?
By applying the reflection and inteference princle of the light to the ColorView® lens, the right wavelengths of light are allowed to pass and absorb reflection. This allows the perception of colour to be altered.
World Class Precision Control
The surface of the lens is coated with an ultra-thin membrane layer. The thickness of the layer is very thin at 0.1µms which is half the length of a wave length of light. Tto accomplish this spectrum in ColorView® lenses, Physical Vapor Deposition technology is applied. See the chart for an example.
There are two different models of ColorView Lenses (Model A and B). Each has its own spectral permeation characteristics. ColorView® makesa total of 8 types. The types are unique based on differences in the wavelength region to which cone cells in the eye respond.
Graph: Model A / Model B (typical permeation rate of a spectrum of light)
|Model A||Model B|
|Model A lenses bring about significant changes in the permeation rate of the light spectrum for people with Red/Green Colour Vision Deficiency who may confuse the "Red" wavelength region and the "Green" wavelength region. (A1 - A5: 5 kinds)||Model B lenses bring about the same permeation rate, but in a shorter wavelength compared to Model A's controlled wavelength region. (B1 - B3: 3 kinds)|
ColorView® are tinted with an active coating. The surface reflects colour as shown in the picture below. Each model reflects different surface colours.
The picture above is a sample of an A-1 type. Models are of the lenses only. Please visit your local Optometrist for a frame of your choosing.
