Pronunciation: [ˈɒptɪk lˈɛnz] (IPA) 
The term "optic lens" is made up of two syllables, with the first syllable pronounced as "ahp-tik" and the second syllable pronounced as "lens." The "o" in "optic" is pronounced as the short "ah" sound, while the "t" sound is softened by the following "i." In "lens," the "e" is pronounced as the short "eh" sound, and the "s" at the end is pronounced as a "z" sound. Together, "optic lens" is pronounced as "ahp-tik lenz."
An optic lens, also known as an optical lens, is a transparent device composed of a material such as glass or plastic that is used to manipulate light, resulting in the formation of an image. The lens has a curved surface that is designed to refract or bend light rays passing through it, focusing them and altering their direction. Optic lenses are extensively utilized in various optical instruments, such as cameras, eyeglasses, microscopes, telescopes, and binoculars, to enhance vision and magnify objects.
The primary purpose of an optic lens is to correct visual abnormalities, such as nearsightedness or farsightedness, by refracting light in a specific manner to compensate for the eye's imperfections. In cameras and telescopes, optic lenses are responsible for focusing and adjusting the incoming light rays, ultimately producing sharp and clear images. They are created with different designs and configurations, including convex, concave, and aspherical shapes, each with its unique optical properties and functionalities.
Optic lenses are constructed using a precision manufacturing process that ensures extreme accuracy and smoothness of their surfaces. They are often coated with special substances to reduce glare, increase light transmission, and minimize reflection, enhancing the overall performance of the lens and reducing optical aberrations. The quality of an optic lens is typically measured by criteria such as its focal length, optical power, and chromatic aberration, as these factors greatly impact the clarity and accuracy of the resulting image.
A ground glass for a telescope or other optical instrument.

The word "optic" comes from the Latin "opticus", which in turn is derived from the Greek word "optikos", meaning "of sight or vision". "Lens", on the other hand, has Latin origins as well, originating from the word "lentil", which referred to the shape of the lentil seed. It was later used to describe the shape of a lens due to its resemblance. In combination, "optic lens" refers to a lens that is used to aid or affect vision.
