Some people believe that consuming certain foods can change the eye color. This is a myth; there is no way to change your eye color with food.

The color of your eyes is determined by genes. Darker eyes tend to have a higher concentration of melanin, which is the pigment that gives your eye its color.

There are three genes responsible for the color of human eyes. Two of these genes account for the most common eye colors (brown, blue, and hazel). The third gene is rare and produces gray eyes.

Your eye color changes as you grow up, and it can be influenced by other factors as well. It may change due to a birth defect such as Horner's syndrome or pigment dispersion syndrome, or it can be caused by illness.

Some people who have lighter eye colors will get darker as they age. This is because the iris muscle expands and contracts to control the size of the pupil. This shrinks when the iris is exposed to bright light, and it expands in dim lighting.

Another way to alter your eye color is by using tinted contact lenses. These do not change the eye color fully but can add depth to your appearance.

You can also use colored contact lenses, which are more colorful than tinted contact lenses and will allow you to see better in low-light conditions. However, you should never use colored contacts for more than a day, as they can lead to infection or blindness.
