#astigmatic

• Anastigmatic — Free from astigmatism; optimally corrected from a geometric and optical standpoint to eliminate asymmetric convergence aberrations of oblique light rays. It is applied to systems, lenses, aspherical surfaces, or light beams capable of forming a perfect point-like image of a point object, offering exceptional flatness of the visual field.
• Astigmatic — A person suffering from astigmatism (a refractive error where light rays do not focus on a single point on the retina due to an irregular curvature of the cornea or lens, causing blurred or distorted vision at any distance); as an adjective, it describes an eye, optical system, or lens affected by or designed to correct this geometric aberration.
• Astigmatic — The feminine form of the word 'astigmat'; a woman or female person suffering from astigmatism; as an adjective, it refers to a manifestation, an ocular anatomical structure, a lens, or an image affected by this refractive error or designed to treat it.
• Astigmatic — Relating to astigmatism, exhibiting this refractive error, or designed for its correction; an adjective used to describe an eye whose cornea has an irregular curvature, a light beam that cannot focus on a single point, or a lens (toric or cylindrical) specifically designed to remedy this geometric aberration; as a noun, it denotes an astigmatic person.
• Astigmatic — The feminine form of the word 'astigmatic'; it refers to a woman affected by astigmatism or to a manifestation, lens, or ocular structure displaying characteristics specific to this optical focusing aberration or used for its correction.
