The document discusses the history and process of manufacturing glass and lenses. It provides details on:
1) Glassmaking has been traced back to 3500 BC based on the oldest glass beads, though its discovery is unknown. Glass was initially used for jewelry before being made into art objects in 16th century BC.
2) When heated to high temperatures, sand melts and becomes glass through a molecular structure change.
3) Lens manufacturing involves measuring a patient's prescription, selecting frames, grinding lenses to the correct optical power, and fitting lenses into frames through processes like cutting, edging and mounting.
4) Resin and glass are the two main materials used for ophthalmic lenses.

The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a material. Materials with a higher refractive index bend light more and allow for thinner lenses. High index lenses have a refractive index greater than 1.49 for plastics and 1.523 for glass. They provide benefits like thinner and lighter lenses but also have disadvantages like increased chromatic aberration. Common materials used include lanthanum, titanium, and polyurethane.
The document discusses different types of materials used to make eyeglasses, including natural minerals, glass compositions like crown glass and flint glass, as well as plastic materials. Crown glass typically contains silica, lime, and soda. Flint glass has a higher refractive index but also higher dispersion, due to its lead content. Early plastic materials included PMMA and CR39, but polycarbonate was introduced as having higher optical quality and strength. A newer material called Trivex is lightweight with impact resistance similar to polycarbonate and a good optical quality. High index plastics can have a refractive index as high as 1.74.
This document discusses various materials used in ophthalmic lenses. It describes the optical, mechanical, electrical, chemical and thermal properties of different lens materials like glass and plastics. Specifically, it provides details on the properties of different types of glass lenses including crown glass, flint glass, barium crown glass, and high index glass. It also discusses plastic lenses and highlights the use of high index lenses for higher prescriptions to reduce lens thickness.
Glass and plastic are the most common materials for ophthalmic lenses. Glass is more scratch-resistant but heavier, while plastic is lighter but requires scratch-resistant coatings. CR-39 plastic was widely used and has a refractive index of 1.498, but newer materials like polycarbonate, Trivex, and high-index plastics provide better optics, impact resistance, and weight. Lens properties like refractive index, Abbe value, density, and impact resistance are considered in material selection.
