Ray-Ban Wayfarer sunglasses and eyeglasses have been manufactured by Ray-Ban since 1952. Made popular in the 1950s and 1960s by music and film icons such as Buddy Holly , Roy Orbison and James Dean , Wayfarers almost became discontinued in the 1970s, before a major resurgence was created in the 1980s through massive product placements .
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.

Geometrical optics. Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometrical optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. The simplifying assumptions of geometrical optics include that light rays:
Aviator style sunglasses are intended to be worn under headgear and are characterised by dark, oftentimes reflective lenses and thin monel, steel or titanium metal frames with double or triple bridges and bayonet earpieces or flexible cable temples that hook more securely behind the ears. [ 1] The large lenses are not flat but slightly convex.
Gradient-index optics. A gradient-index lens with a parabolic variation of refractive index ( n) with radial distance ( x ). The lens focuses light in the same way as a conventional lens. Gradient-index ( GRIN) optics is the branch of optics covering optical effects produced by a gradient of the refractive index of a material.
