My eyes color changes why is that

There are many factors that can cause eyes to change colors—or appear to have different colors—including various diseases, medications and trauma,. This can result in a lighter color to the iris, drooping eyelid, uneven pupil size and the inability to sweat on that side of the face. These patients will often have one brown eye and one blue eye as seen in the photograph above. Cataracts and glaucoma can also occur and lead to vision loss if not treated.

Most older patients have some degree of arcus senilis and this is harmless. Eye color can also change from medication. When you experience a strong emotion, your body releases a hormone that causes your pupils to expand or contract. This hormone, combined with the sudden change in pupil size, can change the hue of your eyes. We are usually born with light blue or gray eyes. As we grow older, our eyes change color and darken.

Meanwhile, chamomile can relax your pupils and make them appear warmer in shade, or a different color entirely. Eye colors depend on how much pigment resides in the iris — the eye structure that surround the pupil and often is called the colored part of the eye. There is only one pigment that determines eye color: It's called melanin. The color of your eyes depends on how much melanin there is in your iris. If you have a lot of melanin, you'll have brown eyes or some other dark eye color. If you have less melanin in the iris, you'll have a lighter eye color.

Yes and no. A child's eye color definitely is influenced by the color of their parents' eyes. But the parents' genes can mix and match in many different ways. At one time, brown eye color was considered "dominant" and blue eye color was considered a "recessive" trait. But modern science has shown that eye color is not that simple.

Eye color isn't just a blend of the parents' eye colors, as in mixing paint. Each parent has two pairs of genes on each chromosome, and multiple possibilities exist for how this genetic information is expressed in terms of eye color. The influences from each parent on eye color aren't fully known until after the child is born and begins to mature.

Brown is the most common eye color worldwide. There are many shades of brown eye color.
