  2. Gradient-index optics - Wikipedia

    en.wikipedia.org/wiki/Gradient-index_optics

    The lens of the eye is the most obvious example of gradient-index optics in nature. In the human eye, the refractive index of the lens varies from approximately 1.406 in the central layers down to 1.386 in less dense layers of the lens. [1] This allows the eye to image with good resolution and low aberration at both short and long distances. [2]

  3. Eye color - Wikipedia

    en.wikipedia.org/wiki/Eye_color

    The total number of genes that contribute to eye color is unknown, but there are a few likely candidates. A study in Rotterdam (2009) found that it was possible to predict eye color with more than 90% accuracy for brown and blue using just six SNPs. [16] [17] In humans, eye color is a highly sexually dimorphic trait. [18]

  4. Anaglyph 3D - Wikipedia

    en.wikipedia.org/wiki/Anaglyph_3D

    Anaglyph 3D images contain two differently filtered colored images, one for each eye. When viewed through the "color-coded" "anaglyph glasses", each of the two images is visible to the eye it is intended for, revealing an integrated stereoscopic image.

  5. Refractive surgery - Wikipedia

    en.wikipedia.org/wiki/Refractive_surgery

    Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. This can include various methods of surgical remodeling of the cornea (keratomileusis), lens implantation or lens replacement.

  6. Progressive lens - Wikipedia

    en.wikipedia.org/wiki/Progressive_lens

    When you look to your right, your right eye views distal (i.e. looking through the lens near to the arm of the spectacles) while your left eye views nasal (i.e. looking through the lens near to the bridge). Modern sophisticated progressive lenses are designed asymmetrically for greater patient acceptance and include special designs to cater to ...

  7. The Rarest Eye Color in the World: What It Is and Why

    www.aol.com/lifestyle/rarest-eye-color-world-why...

    Your eye color is determined by the amount and distribution of melanin in the iris of the eye. And of course, the genes we inherit from our parents play a significant role in determining our eye ...
