ReLEx Small incision lenticule extraction (SMILE), second generation of ReLEx Femtosecond lenticule extraction (FLEx), is a form of laser based refractive eye surgery developed by Carl Zeiss Meditec used to correct myopia, and cure astigmatism.
In humans, eye color is a highly sexually dimorphic trait. [18] Several studies have shown that men are more likely to have blue eyes than women, while women are more likely to have darker eye colors (green and brown eyes) than men. [18] [19] Sex is therefore a major factor in the expression of eye color genotypes. [18]
Eye color, specifically the color of the irises, is determined primarily by the concentration and distribution of melanin. Although the processes determining eye color are not fully understood, it is known that inherited eye color is determined by multiple genes. Environmental or acquired factors can alter these inherited traits. [7]
More melanin means darker eyes, hair or skin. The color of the melanin in the eyes is determined by three other genes, EYCL1, 2 and 3. Together, they account for brown, green and blue, but not ...

Take melanin,the pigment that makes eyes darker. Research reported in the journal Perceptual & Motor Skills found that it not only makes people more susceptible to alcohol, it also helps increase ...
Consequently, Er:glass lasers are classified as relatively eye-safe compared to lasers operating at wavelengths that reach the retina. This relative eye safety allows Er:glass lasers to be used in many different applications where eye safety is preferable or necessary, such as in medicine and in public areas. [1] [2]
The Martin scale is an older version of color scale commonly used in physical anthropology to establish more or less precisely the eye color of an individual. It was created by the anthropologist Rudolf Martin in the first half of the 20th century.
