Color blindness can be defined as a type of visual impairment in which colors or the differences between colors are not understood. Color blindness, which occurs when people realize that they cannot perceive the color red and green, can also occur in the way that all colors are perceived as gray and gray tones, although it is rare.

Who gets color blindness? 

Color blindness can occur in two different ways;

1- Color blindness due to hereditary causes; It can be passed from parents to children via the sex chromosome known as the x chromosome.

2- Acquired, occurring later color blindness; It may occur due to various reasons, such as the side effects of drugs used in the treatment of other diseases, which may occur in cases of certain problems in the retina or the visual center of the brain or damage to the parts that affect vision.  

The incidence of color blindness is higher in men than in women, because men have one X chromosome and women have two X chromosomes. While visual impairment is seen at a rate of 0% in women, this situation increases by 5% in men. 

How is color blindness detected? 

It is recommended that you see an ophthalmologist as soon as possible when it is understood that some colors are difficult to perceive or that some colors are not seen at all. The ophthalmologist can diagnose that you are colorblind after a thorough examination and based on the results of the necessary tests. Color blindness tests You can tell if you are colorblind or not.

If you are half or fully colorblind, you will not be able to read hidden images or numbers made of different colors and dots. Based on the test results, the ophthalmologist can diagnose color blindness.

Can color blindness be treated? 

Special Contact Lenses and Glasses are available to treat Color Blindness. So, there are colored contact lenses and glasses produced for colorblind patients. The ophthalmologist tests different colors from the trial set of these contact lenses and glasses to the patient. It is analyzed which color contact lenses or glasses can distinguish colors better, and then the patient starts to use contact lenses and glasses of this color. Such optical devices do not completely treat color blindness, but they are a very important treatment method for color blindness, especially in terms of distinguishing colors during the day and making daily life easier.
