As a result, most practitioners encourage using other lens styles. [2] The myodisc has been categorized as a lenticular lens. These are rarely prescribed sets of specialty lenses used in cases of extremely poor vision, or near blindness. The lenticular subrogate nomenclature has been extensively used in ophthalmology, requiring scope of context ...
A lenticular lens is an array of lenses, designed so that when viewed from slightly different angles, different parts of the image underneath are shown. [ 1 ] [ 2 ] [ failed verification – see discussion ] The most common example is the lenses used in lenticular printing , where the technology is used to give an illusion of depth, or to make ...
An example of a lenticular fabric sheet that changes from a blue background with white stars to a white background with red stars. A lenticular fabric is a lattice-like arrangement of lens-shaped materials formed into a thin layer. [1] When the surface of the fabric is smooth, it often has a reflective and light-distorting appearance.
Lithographic lenticular printing allows for the flat side of the lenticular sheet to have ink placed directly onto the lens, while high-resolution photographic lenticulars typically have the image laminated to the lens. [citation needed] Lenticular images saw a surge in popularity in the first decade of the 21st century, appearing on the cover ...
Optical lens design is the process of designing a lens to meet a set of performance requirements and constraints, including cost and manufacturing limitations. Parameters include surface profile types (spherical, aspheric, holographic, diffractive, etc.), as well as radius of curvature, distance to the next surface, material type and optionally tilt and decenter.
This list covers optical lens designs grouped by tasks or overall type. The field of optical lens designing has many variables including the function the lens or group of lenses have to perform, the limits of optical glass because of the index of refraction and dispersion properties, and design constraints including realistic lens element center and edge thicknesses, minimum and maximum air ...

A microlens array used in a spectrograph. A microlens is a small lens, generally with a diameter less than a millimetre (mm) and often as small as 10 micrometres (μm). The small sizes of the lenses means that a simple design can give good optical quality but sometimes unwanted effects arise due to optical diffraction at the small features.
