színtéveszt

Színtévesztés, commonly known as color blindness, is a condition that affects a person's ability to distinguish between certain colors. It is not a true blindness, but rather a deficiency in the perception of color. The most common form is red-green color blindness, where individuals have difficulty differentiating between red and green hues. Other forms include blue-yellow color blindness and complete color blindness (achromatopsia), which is extremely rare.

The cause of színtévesztés is typically genetic, inherited from the parents. It is more prevalent in males than females due to the way color vision genes are located on the X chromosome. In rare cases, it can be acquired later in life due to certain diseases, injuries, or medications.

Diagnosis is usually made through standardized color vision tests, such as the Ishihara plates, which are a series of images containing numbers or patterns hidden within dots of various colors. Treatment for genetic színtévesztés is currently not available, but specialized lenses and apps can sometimes assist individuals in distinguishing colors more easily. While it can impact daily life, such as in choosing clothes or interpreting traffic signals, most people with színtévesztés adapt and live normal lives.
