Stigmatismnoun

(optics) Image-formation property of an optical system which focuses a single point source in object space into a single point in image space

Astigmatismnoun

(optics) A defect of a lens such that light rays coming from a point do not meet at a focal point so that the image is blurred.

Stigmatismnoun

(medicine) Normal eyesight, anastigmatic state

Astigmatismnoun

(pathology) A disorder of the vision, usually due to a misshapen cornea, such that light does not focus correctly on the retina causing a blurred image.

Stigmatismnoun

(pathology) State of having stigmata

Astigmatismnoun

A defect of the eye or of a lens, in consequence of which the rays derived from one point are not brought to a single focal point, thus causing imperfect images or indistinctness of vision.

Stigmatismnoun

the condition of having or being marked by stigmata

Astigmatismnoun

(ophthalmology) impaired eyesight resulting usually from irregular conformation of the cornea

Stigmatismnoun

(optics) condition of an optical system (as a lens) in which light rays from a single point converge in a single focal point

Astigmatismnoun

(optics) defect in an optical system in which light rays from a single point fail to converge in a single focal point

Stigmatismnoun

normal eyesight

Astigmatism

Astigmatism is a type of refractive error in which the eye does not focus light evenly on the retina, due to a variation in the optical power of the eye for light coming from different directions. This results in distorted or blurred vision at any distance.

Stigmatism

In geometric optics, stigmatism refers to the image-formation property of an optical system which focuses a single point source in object space into a single point in image space. Two such points are called a stigmatic pair of the optical system.
