Color Blindness Can Be Inherited or Acquired

The most common types of color blindness are genetic, which means they are passed from parents to children. If your color blindness is inherited, your color vision will not improve or worsen over time. You can develop color vision deficiency later in life due to age, illness, injury, or by coming into contact with a substance that affects your eyes or brain. Often times, the cause of color blindness determines the severity of the symptoms and whether or not the color blindness can be treated.

How can color blindness be passed from parent to child? Conditions like color blindness are passed from parent to child through groups of genes called chromosomes. Chromosomes are structures that contain genes. Genes are the instructions for the development of cells, tissues and organs. If you are color blind, it means that the gene cells are defective. The cone cells may be missing or less sensitive to light, or the path from the cone cells to the brain may not have developed properly.

Some of these, called X and Y chromosomes, will determine whether a person is born male or female. Males have 1 X and 1 Y chromosome, and females 2 X chromosomes.

The genes that can determine if your red-green color blindness are transmitted through the X chromosome. Since it is transmitted through the X chromosome, red-green color blindness is more color blind correction glasses philippines
common in men. This condition is due to males having only 1 X chromosome from the mother. If that X chromosome has the gene for red-green color blindness instead of a normal X chromosome, you will have red-green color blindness. Females have 2 X chromosomes, one from the mother and one from the father. To have red-green color blindness, both X chromosomes would need to have the gene that creates this type of color blindness.

Other sex chromosomes transmit blue-yellow color blindness and complete color blindness, thus affecting men and women equally.
