Contact Lenses: Materials, Chemicals, Methods and Applications

With research & development continuing in the field, this comprehensive book takes a look at the last 10 years in terms of new materials, chemistry methods, applications and fabrication techniques. New applications include drug delivery, lenses for augmented reality, electronic contact lenses, and wearable smart contact lenses.It discusses simulation methods for contact lenes, such as ocular topography parameters, gas permeable lenses, and computerized videokeratography. On the fabrication front, several common fabrication methods for contact lenses are detailed, including the computer-aided contact lens design, methods for the fabrication of colored contact lenses, and the fabrication of decentered contact lenses. Special processes are reviewed, including, mold processes, reactive ion etching, electrospinning, and others. Also discussed are the properties of contact lenses and methods for the measurement. Many of the standard methods are discussed, but other issues are taken up too including discussed the assessment of cytotoxic effects, the Schirmer tear test and others.
