For most children , eye color stops changing after the first year, but for some kids the color can continue to change for several more years. The Academy surveyed more than 2, Americans to determine what color eyes they have. Below are the results of that Harris Poll survey, weighted to reflect the United States population at that time.
About Foundation Museum of the Eye. Eye Facts and Science. Los ojos azules no son realmente azules. By Dan T. Hint: Eye color depends on the iris The colored part of the eye is called the iris. The front layer of the iris called the stroma can make eyes appear brown, blue or green For people with brown eyes , some of the cells also have brown pigment in them.
People with blue eyes have no pigment at all in this front layer, causing the fibers to scatter and absorb some of the longer wavelengths of light that come in. Some members of the indigenous Buton tribe have prominent blue eyes because of a rare condition known as Waardenburg Syndrome.

So don't be concerned if your child begins to lose that "baby blue" eye colour and their eyes become green, hazel or brown as they get a little older.
Melanin in the iris of the eye appears to help protect the back of the eye from damage caused by UV radiation and high-energy visible "blue" light from sunlight and artificial sources of these rays. Because blue eyes contain less melanin than green, hazel or brown eyes, they may be more susceptible to damage from UV and blue light. Regarding connections between eye colour and eye diseases, research has shown darker iris colour is associated with an increased risk of cataract and a reduced risk of ocular uveal melanoma a form of eye cancer , compared with blue eyes.
But the same analysis of published studies failed to confirm any association of eye colour with increased risk of age-related macular degeneration AMD. Still, because many people with blue eye colour are sensitive to light and may have more risk of damage to their retinas from UV light, most opticians recommend that people with blue eyes should be extra cautious regarding their exposure to sunlight.
And because eye damage from UV and blue light appears to be related to your lifetime exposure to these rays, wearing sunglasses that block percent UV and most blue light should begin as soon as possible in childhood.
Photochromic lenses are another great way to protect blue eyes from UV radiation. These clear lenses block percent UV both indoors and outside, and darken automatically in response to sunlight when you go outdoors so you don't have to carry a separate pair of sunglasses. Also, adding an anti-reflective coating to photochromic lenses gives you the best vision and comfort in all lighting conditions including driving at night while showcasing your blue eyes with reflection-free lenses.
