How does it work?
- Multinotch filtering cuts out sharp wavelengths of light to enhance specific colors.
- The EnChroma lenses will separate the overlapping red and green cones.
- They re-establish the correct balance between the signals from the three photopigments in the eye.
- The lenses excite the neural mechanisms of vision, therefore allowing the correct color perception.

How do EnChroma glasses work?
To understand how Enchroma glasses work, it helps to know how color vision works normally and how it goes awry in cases of color blindness. When light enters your eye, it is detected by two types of photoreceptive cells called ‘rods’ and ‘cones’.
How does EnChroma work for color blindness?
As a result, the number of shades of color a typical color blind person can see may be reduced by as much as 90%. EnChroma develops optical lens technology that selectively filters out wavelengths of light at the precise point where this confusion or excessive overlap of color sensitivity occurs.
What are EnChroma lenses made of?
Every lens is made with Trivex® lens material, an optical-grade resin. All EnChroma lenses are 100% UVA and UVB absorbing for maximum sun protection. Optimal sun protection is vital for children's developing eyes. All lenses are anti-reflective on both sides to maximise clarity and reduce haze.

Do blind people see black?
The answer, of course, is nothing. Just as blind people do not sense the color black, we do not sense anything at all in place of our lack of sensations for magnetic fields or ultraviolet light.13-Aug-2014
Can color blindness get worse?
Colour vision deficiency is not usually anything to be concerned about. Most people get used to it over time, it will not normally get any worse, and it's rarely a sign of anything serious. But it can sometimes cause issues such as: difficulty at school if colours are used to help with learning.
Can you go colorblind over time?
Unlike inherited colour blindness , acquired colour blindness can vary over time. Symptoms may be mild and remain stable or they can be severe and progress to more serious forms of colour blindness, such as monochromatism, very quickly. Often the cause of colour blindness determines how severe the symptoms will be.
How well do colorblind glasses work?
So color-blindness glasses don't “fix” color-blindness, but they can make it easier for people — color-blind or not — to tell colors apart. It should be noted that because there are different types of color-blindness, for some people, these glasses won't do anything at all.20-Feb-2019

What is Colour Blindness?
Most types of colour blindness occur when there is an excessive overlap of the M (green) and L (red) colour cones in the eye, causing distinct hues to become indistinguishable. As a result, the number of shades of colour a typical colour blind person can see may be reduced by as much as 90%.
Will EnChroma Colour Blind Glasses Work for Me?
Colour blindness is not a singular condition. It encompasses a range of conditions, from mild to severe, that can cause each person to see colour differently. EnChroma glasses are designed to improve colour vision of people with forms of anomalous trichromacy, which are estimated to comprise four out of five cases of colour blindness. The most common types are Protanomaly and Deuteranomaly, which are forms of partial red-green colour blindness. In the most extreme cases, the complete absence of one of the cone photopigments, called Protanopia or Deuteranopia, are considered dichromats who may see limited results due to the complete inability to see red and green colour differences. Reduced colour discrimination of shades of blue and yellow is called Tritanomaly, or Tritanopia which is not a type of what is commonly referred to as red-green colour blindness, but is also a form of colour vision deficiency. EnChroma glasses are designed to address forms of red-green colour blindness and are not intended to assist the vision of people with Tritan-type deficiency. Fortunately, most cases of colour blindness respond well to EnChroma spectral lens technology, enabling the perception of bright, vibrant colour. Learn more about types of colour blindness.

Why are enchroma glasses used?
In its original form, his glasses technology was designed to aid and protect surgeons performing laser surgery. Heavy metals embedded in the lenses absorbed significant amounts of light to keep the surgeons safe. In addition to increased safety, the glasses increased the saturation of most colors, making it easier to distinguish blood from tissue during surgery.
How do you know if you see light?
When light enters your eye, it is detected by two types of photoreceptive cells called ‘rods’ and ‘cones’. Rod cells detect dim light and help you see at night, while cone cells detect brighter light and help you see during the day. Humans have about 120 million rods and 6 million cones in each retina. Cone cells come in three flavors that are each maximally sensitive to a different wavelength of light: blue, red, or green. Our ability to distinguish a rich diversity of color is a result of this trichromatic system.
Why are color blind people so hard to distinguish?
Red-green color blind individuals have difficulty distinguishing color because their cones have increased overlapping wavelength detection. Enchroma sharpens color perception by filtering out the overlapping region.
What Are EnChroma Lenses?
EnChroma lenses are the product of years of careful research and engineering. Today, they can deliver the highest possible range of vision available to people who are color blind. EnChroma color deficiency glasses help increase color contrast, thus helping someone who has a color deficiency distinguish between colors.

Why are enchroma lenses used?
EnChroma lenses were originally created as a type of eye protection for surgeons performing laser surgery. They look like regular sunglasses but are coated with a special material that exaggerates some wavelengths of light and blocks others. By blocking some of the wavelengths of light coming into the eye, the red and green light wavelengths don’t overlap as much as they usually do. This allows the brain to see each colour quicker and clearer.
How does colorblindness affect people?
Colour-blindness doesn’t just impact the way people see the world, it affects many aspects of their everyday lives, including the opportunities that are available to them. In fact, people with the condition can’t pursue piloting, electrical work and a number of other professions.
What color glasses did Jimmy's dad wear?
“Orange?”. Jimmy answered. “It’s green,” his father replied. Jimmy was then handed a pair of color-blindness glasses from EnChroma while onlookers held up balloons and a boldly colored beach towel.
What is the purpose of enchroma glasses?
The EnChroma glasses use a filter to cut out these overlapping wavelengths, allowing for a clearer distinction between colors, especially red and green. The invention was derived from the work of Don McPherson, who earned his PhD in glass science at Alfred University.
Why do the wavelengths of light that these three cones absorb have overlapping regions?
Color-blindness is often a result of a malfunctioning cone that causes wavelengths to overlap even more, resulting in poor color discrimination.
