\"\"<\/a><\/p>\n

A retina is basically made up of photoreceptors known as cones and rods.<\/p>\n

Rods are present in the periphery of our retina and they are involved in night vision.<\/p>\n

On the other hand, the cones are located in the center of the retina and the cones help us to perceive color the in daytime.<\/p>\n

The cones are responsive to different wavelengths of light. The reason is that they are genetically coded in the type and amount of pigmentation.<\/p>\n

The X chromosome holds the genes that generate the pigments in the cones that are required to discriminate color.<\/p>\n

In case, if the genes that code the cones intensity of pigment are coded wrongly then it means that the pigments are wrong.<\/p>\n

This is the reason of color blindness or color deficiency.<\/p>\n

Reason of Color Blindness<\/h1>\n

\"\"<\/a><\/p>\n

According to the study it is found that males are suffering from color blindness on a larger scale as compare to females.<\/p>\n

The poor cone growth will lead to the poor acuity of color, particularly with the three main colors i.e. green, red and blue.<\/p>\n

Usually, in protanopia, there is a lack of red photo receptors and red looks like black.<\/p>\n

There is also a reduced sensitivity of yellow and orange.<\/p>\n

The deuteranopsia is the deficiency of green receptors.<\/p>\n

This problem is rare but can occur in people of all age group. Tritanopia is another problem.<\/p>\n

This problem occurs due to the deficiency of blue receptors. Some other reasons of color blindness are age related disorders such as\u00a0diabetic retinopathy, macular degeneration,\u00a0trauma,\u00a0and the deficiency of vitamin A.<\/p>\n

Cataracts and Glaucoma\u00a0can also have an effect on color sensitivity.<\/p>\n

Different barbiturates, high blood pressure medications and antibiotics can also affect the color perception.<\/p>\n

How to diagnose the problem?<\/h1>\n

\"\"<\/a><\/p>\n

The inherited color vision insufficiency is generally diagnosed in early childhood with the use of easy screening tests.<\/p>\n

Different tests like Ishihara Color Plates and The Hardy-Rand-Rittler, commonly known as H-R-R\u00a0are used to evaluate the degree and type of color insufficiency.<\/p>\n

In both of the tests, the individual is asked to classify the colored shapes or numbers that lie in a mixture of dots and differ in strength and color.<\/p>\n

The physicians distinguish and classify the insufficiency based on the person’s responses.<\/p>\n

Always keep this in your mind that hereditary color vision deficiency\u00a0cannot be cured or treated.<\/p>\n

Different types of measures can be taken in order to deal with this problem.<\/p>\n

Some of the people develop their own structure of recognizing different colors by their location or brightness, such as the points of yellow, green and red in a traffic light.<\/p>\n

The colored lenses and specialized glasses are also available in the market which helps in normalize colors.<\/p>\n

\"\"<\/a><\/p>\n

Get Vision<\/a> to assure that you will not have to miss the words and figures because of your colorblindness issue.<\/p>\n

It will help you manage the screen according to the colors that you can see clearly.<\/p>\n

Cambridge color test<\/h1>\n

\"\"<\/a><\/p>\n

Cambridge color test is also one of the common types of test which is taken in order to diagnose color blindness.<\/p>\n

This test is like Ishihara color test, but it’s taken on a computer screen.<\/p>\n

In this test, the patient is asked to pick out the letter C from different painted backgrounds.<\/p>\n

You can complete the Vision test available at\u00a0https:\/\/iristech.co\/test-vision<\/a>.<\/p>\n

It is better that you find out today whether you are colorblind or not.<\/p>\n","protected":false},"excerpt":{"rendered":"
