Difference between Corrective lens and Lens (optics)

Corrective lens vs. Lens (optics)

A corrective lens is a lens typically worn in front of the eye to improve vision. A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.

Similarities between Corrective lens and Lens (optics)

Corrective lens and Lens (optics) have 20 things in common (in Unionpedia): Abbe number, Aspheric lens, Astigmatism, Astigmatism (optical systems), Contact lens, Dioptre, Dispersion (optics), Far-sightedness, Fluorite, Focus (optics), Glasses, Human eye, Lens (optics), Near-sightedness, Optical power, Photochromic lens, Presbyopia, Refractive index, Retina, Toric lens.

Abbe number

In optics and lens design, the Abbe number, also known as the V-number or constringence of a transparent material, is a measure of the material's dispersion (variation of refractive index versus wavelength), with high values of V indicating low dispersion.

Aspheric lens

An aspheric lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder.

Astigmatism

Astigmatism is a type of refractive error in which the eye does not focus light evenly on the retina.

Astigmatism (optical systems)

An optical system with astigmatism is one where rays that propagate in two perpendicular planes have different foci.

Contact lens

A contact lens, or simply contact, is a thin lens placed directly on the surface of the eye.

Dioptre

A dioptre (British spelling) or diopter (American spelling) is a unit of measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in metres.

Dispersion (optics)

In optics, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency.

Far-sightedness

Far-sightedness, also known as hyperopia, is a condition of the eye in which light is focused behind, instead of on, the retina.

Fluorite

Not to be confused with Fluoride. Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2.

Focus (optics)

In geometrical optics, a focus, also called an image point, is the point where light rays originating from a point on the object converge.

Glasses

Glasses, also known as eyeglasses or spectacles, are devices consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person's eyes, typically using a bridge over the nose and arms which rest over the ears.

Near-sightedness

Near-sightedness, also known as short-sightedness and myopia, is a condition of the eye where light focuses in front of, instead of on, the retina.

Optical power

Optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light.

Photochromic lens

Photochromic lenses are optical lenses that darken on exposure to specific types of light of sufficient intensity, most commonly ultraviolet (UV) radiation.

Presbyopia

Presbyopia is a condition associated with the aging of the eye that results in progressively worsening ability to focus clearly on close objects.

Refractive index

In optics, the refractive index or index of refraction of a material is a dimensionless number that describes how light propagates through that medium.

Retina

The retina is the innermost, light-sensitive "coat", or layer, of shell tissue of the eye of most vertebrates and some molluscs.
