Perspex has been used as a surface to paint on, for example by Salvador Dalí. Diasec is a process which uses acrylic glass as a substitute for normal glass in picture frames. This is done for its relatively low cost, light weight, shatter-resistance, aesthetics and because it can be ordered in larger sizes than standard picture framing glass.
For some patients, losing an eye presents an opportunity to invent a replacement that is more expressive than a simple replication of their remaining eye. David fumbles for a plastic packet containing several prosthetics with icons and imagery instead of regular irises – he sifts through a painted smiley-face, a skull and crossbone, a bald ...
An ocular prosthesis, artificial eye or glass eye is a type of craniofacial prosthesis that replaces an absent natural eye following an enucleation, evisceration, or orbital exenteration. Someone with an ocular prosthesis is altogether blind on the affected side and has monocular (one sided) vision .
Optical glass refers to a quality of glass suitable for the manufacture of optical systems such as optical lenses, prisms or mirrors.Unlike window glass or crystal, whose formula is adapted to the desired aesthetic effect, optical glass contains additives designed to modify certain optical or mechanical properties of the glass: refractive index, dispersion, transmittance, thermal expansion and ...
A facial prosthetic or facial prosthesis is an artificial device used to change or adapt the outward appearance of a person's face or head. When used in the theater, film, or television industry, facial prosthetic makeup alters a person's normal face into something extraordinary.
Enamel is glass, not paint, so it does not fade under ultraviolet light. [28] A disadvantage of enamel is a tendency to crack or shatter when the substrate is stressed or bent, but modern enamels are relatively chip- and impact-resistant because of good thickness control and coefficients of thermal expansion well-matched to the metal.
A visual prosthesis, often referred to as a bionic eye, is an experimental visual device intended to restore functional vision in those with partial or total blindness. Many devices have been developed, usually modeled on the cochlear implant or bionic ear devices, a type of neural prosthesis in use since the mid-1980s.
