ANASTIGMATIC Meaning and
Definition
-
Anastigmatic is an adjective that refers to something that is free from or corrected for astigmatism, which is a condition affecting the eye's ability to focus light properly. In the context of optics or lens design, anastigmatic means that a lens or an optical system has been designed or corrected in such a way that it does not introduce astigmatism, resulting in clear and distortion-free images.
The term anastigmatic is commonly used in the field of ophthalmology and optometry to describe a person's vision, particularly after receiving corrective treatments or wearing glasses or contact lenses. An anastigmatic lens or optical system ensures that light entering the eye is focused uniformly on the retina, rather than having certain points of the image appearing more blurred or distorted than others.
In addition to its ophthalmological context, anastigmatic can also describe devices or instruments used in various fields, such as photography or microscopy, where precise and accurate image reproduction is crucial. These devices employ specially designed lenses or optical systems to eliminate astigmatism and provide clear, sharp, and undistorted images.
Overall, anastigmatic refers to the absence or correction of astigmatism, ensuring optimal visual clarity and accurate image reproduction in ophthalmological, optical, and related contexts.
