Examples of 'cylindrical lenses' in a sentence
Meaning of "cylindrical lenses"
Cylindrical lenses are a type of optical lens that have curved surfaces along one axis, while the other axis remains flat. They are used to correct astigmatism and other vision disorders. Cylindrical lenses are commonly found in eyeglasses and contact lenses, helping to focus light on the retina correctly. They are also utilized in various optical instruments, such as cameras, microscopes, and telescopes for image correction and magnification
