Most people with color vision deficiency (QOL) can see colors. However, they cannot distinguish between these colors:

Specific shades of green and red, which are very common.
Yellow and blue, which are less common.
That being said, those who are completely color blind (achromatopsia), can only see things in white, black or shades of gray.

What Causes Cardiovascular Disease?

Normally, color vision deficiency is a genetic condition. It is caused by a recessive gene linked to the normal X chromosome, which is passed from a mother to her child. Another cause of this condition is an injury or disease that destroys the retina or optic nerve.


Also, CVD can range from mild to severe, but it depends on the cause. If inherited, it can affect both eyes. On the contrary, if it is caused by illness or injury, it only affects one eye.

How is color vision deficiency treated?

Hereditary color deficiency has no cure, but if it is the result of an eye injury or disease, treating the condition can improve color vision.

Now, every person with color vision deficiency has a wish: I would love to see things and discern colors like everyone else. With eyeglasses and color correction lenses, you can get what you want.

Color correcting glasses vs. contact lenses: which one should you choose? Let’s find out, shall we?

Contact lenses

Yes, contact lenses can help give vision to people who are nearsighted or farsighted. But can they correct color blindness? Dr. Azman has created the ColorCorrection System – ColorCorrective Contact Lens that helps ALL types of color blindness.

The most common type of color vision deficiency affects the green and red areas of the spectrum. When green and red light enter the eye, it activates the green and red sensitive cones simultaneously. What this means is that people with cardiovascular disease cannot easily distinguish between the colors green and red.

What those affected will see is a dull yellow-brown, which can hinder day-to-day activities, such as looking at traffic lights.

There is a study that aims to solve the problem by using gene therapy to create new cones in monkeys with color vision deficiency, while Dr. Azman has developed ColorCorrection System ™ to correct the problem of color vision .

His novel system is the only “solution” for color blindness with a 100% success rate to pass the Ishihara color plate test. The system works by using individualized filters to alter the wavelength of each color that enters the eyes.

These filters are specially designed for each individual. Additionally, the filters can be designed as color blind contact lenses. In addition, contact lenses correspond to the curvature of the eye, offering a wider range of vision.

What are the benefits of wearing contact lenses?

Contact lenses for color blindness cause fewer obstructions and distortions of vision.
Contact lenses will not prevent you from exercising or playing sports. It doesn’t clash with your outfit (if you pay attention to what you wear, most people do)
In general, weather conditions do not affect contact lenses; they don’t fog up in winter like glasses.
Color-corrected aspherical lenses help reduce spherical and chromatic anomalies, making them perfect for many applications where image quality and accurate results are important.
Color correction lenses do not change their natural appearance and are comfortable for most wearers.
The disadvantages…

Some people find it difficult to apply color-correcting contact lenses. However, good practice and technique can solve this problem.
Wearing contact lenses can decrease the amount of oxygen your eyes receive. Also, it can cause or worsen dry eye syndrome.
Wearing contact lenses while working on a computer can cause computer vision syndrome. And doing this can often make symptoms worse.
Contact lenses need proper care. Clean the lens and case extensively daily to prevent potentially serious eye infections. If committing to a daily care routine is a problem, you can use daily disposables.
Some patients cannot wear contact lenses for painless color blindness
