EnChroma Glasses for the Color Blind
What Are EnChroma Glasses?
EnChroma glasses are lenses that have been specifically engineered for people suffering from color blindness. The color blind glasses allow them to see a wider spectrum of bright color. The innovation has been proven to help 80% of people with color-blindness. They are essentially made up of a lens technology that features a patented light filter. This is applied incredibly carefully, and primarily targets red-green color-blindness, which is the most common kind. It is worth noting that EnChroma glasses are not quite a cure for color-blindness. An eye exam from a professional optician is required to establish whether it is possible to have the condition treated.
To help understand the use of Enchroma glasses, let's take a look at what color-blindness is.
Normal color Vision:
White light is actually made up of the different colors of the rainbow. When it enters the eye, three different parts of the visible spectrum are recognised: blue, green and red. The colors are picked up by color-sensitive photoreceptors found within photopigments.
The most common form of color-blindness occurs when the green and red color receptors overlap. This makes the two colors hard to distinguish for the viewer. In the worst cases, the various shades of a hue can be reduced by up to 90%.
Who Are EnChroma Glasses For?
Red-green color-blindness is the most frequently found form of the condition. It affects just under 5% of the global population, which represents about 350 million people. However, men are more likely to suffer from color-blindness than women. It is estimated that around one in twelve men experience difficulties distinguishing red from green, compared to just one in 200 women. This is caused by the way our genetics work, with the genes for color-blindness appearing on the X-chromosome. Consequently, the condition is passed on by women, but rarely affects them.
As for color-blindness between blue and yellow, this is thought to affect a similar number of people around the world as red-green color-blindness. However, rather than occurring at birth, this form of the condition tends to worsen over time. As a result, the number of cases of blue-yellow blindness is increasing thanks to our ageing population.
Other types of color-blindness do exist, but they are so rare that they only impact 1 in 2000 people. Nevertheless, this can vary between different subpopulations.

How do EnChroma Glasses Work?
The EnChroma lens was initially developed by a glass scientist in the early 2000s. The technology was supposedly discovered by accident, and has since undergone intense clinical research for over a decade. It works by filtering out light wavelengths at the exact spot where the color receptors overlap each other. The two photoreceptors are changed to increase differentiation between colors along the line of confusion for that person’s eyes.
It is worth taking into account that as part of the process, less light is permitted to enter the eye. As a consequence, it is not advisable to wear such lenses at night. Users are also warned not to wear them while driving, for safety reasons.
Do EnChroma Glasses Work?
EnChroma glasses aim to support four out of five cases of red-green color-blindness. It cannot guarantee a 100% success rate because there are different levels of severity for color-blindness, ranging from mild to severe. In strong cases of color-blindness, the patient will achieve limited results from EnChroma glasses owing to their complete lack of color vision. However, the vast majority of people with red-green color-blindness will be able to see much brighter vibrant colors while wearing the glasses. This can save people embarrassment and endless questions like “what color do you think that tree is?”. The glasses can also enable those in the creative industries to express themselves without the fear of getting a color wrong. Although EnChroma glasses will not facilitate those with red-green color-blindness to enter the airforce. Nevertheless, the glasses may come in handy when ensuring those with the color blind condition swallow the correctly colored medical pill.
EnChroma glasses are also solely designed to treat red-green color-blindness. This means that those who struggle to distinguish blue and yellow will not be able to benefit.
EnChroma glasses don’t just solve color-blindness, they offer other perks too. One example is that they ensure 100% protection from the sun’s UV rays. In addition, the lenses are oleophobic and hydrophobic. This means that the surface repels dust, water and sweat, which renders them very easy to clean. You can find this type of lens at SmartBuyGlasses too, as we offer different types of lens coatings, such as scratch resistance and blue light blocking.

Color Blind Contact Lenses
A good alternative to EnChroma glasses are contact lenses. A well reputed brand is called ColorMax, which was developed by Dr Thomas Azman. The doctor’s color Correction System can be applied to both glasses and contact lenses. Another brand of contact lenses for color-blindness includes Chroma-Gen, which was invented by the Brits. They offer both contacts and glasses, and claim to correct more than just red and green color deficiencies, with 8 color tints on offer. The tint is located over the pupil, and in most cases, cannot be seen by others. An extra benefit of ChromaGen is that the lenses can also support those with dyslexia, as the color tints help clarify the words on the page.
