CONTACT LENSES The book focuses on the chemistry and properties of contact lenses and their fabrication methods. 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. In addition, the book discusses simulation methods for contact lenses, 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 a discussion on the assessment of cytotoxic effects, the Schirmer tear test, and others. The book concludes with a chapter detailing the possible medical problems related to contact lenses and how to avoid them. These include eye diseases, allergic and toxic reactions, as well as methods for medical treatment such as disinfection agents. Audience The book will be used by chemists, polymer scientists, ophthalmologists, engineers in the contact lens industry as well as polymer industries.
All marks should be positioned near the lens edge so that there is no risk of visual interference; ideally, both lenses should be engraved. Lens engraving marks are prone to deposition and may be inadvertently removed when power ...
