The color of our eyes, more precisely the color of the iris, is primarily determined by the concentration and redistribution of melanin, i.e. pigment. Due to improper development of the iris of the eye, caused by a violation of its pigmentation, the iris receives a different amount of melanin (pigment), and due to an excess or lack of melanin in the iris of the eye, a different color of the iris appears. This condition when a person has different colored eyes is called heterochromia.
It is very important to emphasize that heterochromia most often does not represent a serious health condition, as it does not affect visual acuity.
Types of heterochromia
Heterochromia can be congenital, ie. congenital (a genetic trait that is inherited from parents or extended family members), which is more common, or acquired, which occurs less often (due to physical damage to the iris, inflammation, consumption of a certain group of drugs for the treatment of glaucoma, or due to tumors).
Also, heterochromia can be complete (when one iris is a completely different color from the other, e.g. one eye is blue and the other is brown) or partial (when one part of the iris is a different color than the rest of the iris), which is often experienced by people suffering from hereditary autoimmune diseases such as Hirschsprung’s disease and Waardenburg syndrome.
Celebrities with different eye color
Many famous people have different eye color, which did not prevent them from achieving success in their field. Some of the most famous are David Bowie, Robert Downey Jr., Mila Kunis, Kate Bosworth, Olivia Wilde, Aleksandar Makedonski, etc.
Heterochromia in animals
Different eye color is a much more common occurrence in animals, and most often occurs in dogs (Siberian Huskies and Australian Shepherds) and cats (mainly cats with white fur).
Find answers to the most common questions about laser vision correction, cataracts and lens implantation. Everything you need to know before deciding on a procedure.
No, the procedure is completely painless. It takes only a few minutes, and as early as the next day you can function normally without glasses or lenses.
If you notice that your vision is blurry, colors are fading and you struggle to drive at night, these are clear warning signs. Surgery restores clear vision and once cataracts are diagnosed, it should not be postponed.
The biggest advantage is that you forget about glasses – both for near and far. This means you can read a book, use your phone and drive without additional visual aids.
You absolutely do! Toric lenses are specifically designed to correct astigmatism and provide clear vision.
These are artificial lenses that are placed inside the eye, while your natural lens remains untouched. They are an excellent option for younger people with high diopters who are not candidates for laser vision correction.
