  2. Optics and vision - Wikipedia

    en.wikipedia.org/wiki/Optics_and_vision

    The human eye is an organ which reacts to light for several purposes. As a conscious sense organ, the eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can distinguish about 10 million colors. [3]

  3. Laser blended vision - Wikipedia

    en.wikipedia.org/wiki/Laser_blended_vision

    The dominant eye is determined and vision tested to identify the level of correction required for distance and near on the dominant eye and non-dominant eye. The analysis of ocular dominance and patient specific interocular suppression and binocular rivalry [ 12 ] also allows for ensuring the eyes can work together to create the Laser Blended ...

  4. Maddox rod - Wikipedia

    en.wikipedia.org/wiki/Maddox_rod

    The strength of the prism is increased until the streak of the light passes through the centre of the prism, as the strength of the prism indicates the amount of deviation present. The Maddox rod is a handheld instrument composed of red parallel plano convex cylinder lens , which refracts light rays so that a point source of light is seen as a ...

    en.wikipedia.org/wiki/Low-density_parity-check_code

    LDPC encoder. During the encoding of a frame, the input data bits (D) are repeated and distributed to a set of constituent encoders. The constituent encoders are typically accumulators and each accumulator is used to generate a parity symbol.

  6. Designer baby - Wikipedia

    en.wikipedia.org/wiki/Designer_baby

    A designer baby is a baby whose genetic makeup has been selected or altered, often to exclude a particular gene or to remove genes associated with disease. [1] This process usually involves analysing a wide range of human embryos to identify genes associated with particular diseases and characteristics, and selecting embryos that have the desired genetic makeup; a process known as ...

  7. Corrections - Wikipedia

    en.wikipedia.org/wiki/Corrections

    A correctional system, also known as a penal system, thus refers to a network of agencies that administer a jurisdiction's prisons, and community-based programs like parole, and probation boards. [3] This system is part of the larger criminal justice system, which additionally includes police, prosecution and courts. [4]

  8. Prism (optics) - Wikipedia

    en.wikipedia.org/wiki/Prism_(optics)

    Prism spectacles with a single prism perform a relative displacement of the two eyes, thereby correcting eso-, exo, hyper- or hypotropia. In contrast, spectacles with prisms of equal power for both eyes, called yoked prisms (also: conjugate prisms , ambient lenses or performance glasses ) shift the visual field of both eyes to the same extent.

  9. Porro prism - Wikipedia

    en.wikipedia.org/wiki/Porro_prism

    Porro prisms are most often used in pairs, forming a double Porro prism. A second prism rotated 90° with respect to the first, is placed such that light will traverse both prisms. The net effect of the prism system is a beam parallel to but displaced from its original direction, with the image rotated 180°.
