  2. Cone cell - Wikipedia

    en.wikipedia.org/wiki/Cone_cell

    S cones respond most strongly to blue short-wavelength light, peaking at 420 nm, and make up only around 2% of the cones in the human retina. The peak wavelengths of L, M, and S cones occur in the ranges of 564–580 nm, 534–545 nm, and 420–440 nm nm, respectively, depending on the individual.

  3. Photoreceptor cell - Wikipedia

    en.wikipedia.org/wiki/Photoreceptor_cell

    Distribution of rods and cones along a line passing through the fovea and the blind spot of a human eye [7] Most vertebrate photoreceptors are located in the retina. The distribution of rods and cones (and classes thereof) in the retina is called the retinal mosaic. Each human retina has approximately 6 million cones and 120 million rods. [8]

    The human eye is a sensory organ in the visual system that reacts to visible light allowing eyesight. ... (photoreceptor cones and rods) ...

  5. Spectral sensitivity - Wikipedia

    en.wikipedia.org/wiki/Spectral_sensitivity

    It is known that the rod cells are more suited to scotopic vision and cone cells to photopic vision, and that they differ in their sensitivity to different wavelengths of light. [ 2 ] [ 3 ] It has been established that the maximum spectral sensitivity of the human eye under daylight conditions is at a wavelength of 555 nm , while at night the ...

  6. LMS color space - Wikipedia

    en.wikipedia.org/wiki/LMS_color_space

    Normalized responsivity spectra of human cone cells, S, M, and L types (SMJ data based on Stiles and Burch [1] RGB color-matching, linear scale, weighted for equal energy) [2] LMS (long, medium, short), is a color space which represents the response of the three types of cones of the human eye , named for their responsivity (sensitivity) peaks ...

  7. Color vision - Wikipedia

    en.wikipedia.org/wiki/Color_vision

    The RGB color model, therefore, is a convenient means for representing color but is not directly based on the types of cones in the human eye. The peak response of human cone cells varies, even among individuals with so-called normal color vision; [8] in some non-human species this polymorphic variation is even greater, and it may well be adaptive.

  8. Fovea centralis - Wikipedia

    en.wikipedia.org/wiki/Fovea_centralis

    The fovea centralis is a small, central pit composed of closely packed cones in the eye.It is located in the center of the macula lutea of the retina. [1] [2]The fovea is responsible for sharp central vision (also called foveal vision), which is necessary in humans for activities for which visual detail is of primary importance, such as reading and driving.

  9. Layer of rods and cones - Wikipedia

    en.wikipedia.org/wiki/Layer_of_rods_and_cones

    The elements composing the layer of rods and cones (Jacob's membrane) in the retina of the eye are of two kinds, rod cells and cone cells, the former being much more numerous than the latter except in the macula lutea. Jacob's membrane is named after Irish ophthalmologist Arthur Jacob, who was the first to describe this nervous layer of the ...
