While acrylic’s refractive index is usually close to the values reported below, this can be adjusted by copolymerization with other monomers. Fluoroacrylate monomers can lower the index. Conversely, incorporating monomers that contain nitrogen or bromine can increase its index of refraction. More rece...
on a base material then forming a cured silicon resin layer thereon and forming further an antireflecting layer consisting of an inorg. material. CONSTITUTION:A resin for a primer is determined by combinations of an acrylic resin and/or methacrylic resin and arom. vinyl resin and is more ...
high refractive index of the optical plastic materials. Introduction Amongst several optical properties, refractive index is one of the most important criteria for selection of materials suitable for application in optics. Conventionally, glass has been the most common material for making various types ...

FIELD OF THE DISCLOSURE This disclosure is directed to compositions comprising reactive monomer mixtures, which when polymerized form an acrylic material having a high refractive index and a high Abbe number. These materials, which may have an editable refractive index, are designed for use in ophtha...
PMMA, silicone, and acrylic intraocular lenses (IOLs) consist of materials that vary in the index of refraction between 1.40 and 1.56.[24]The index of refraction determines the thickness of the IOL and can impact surgical outcomes such as the risk of post-surgical glare from internal and lens...
Metal compounds such as hydroxides, oxides, carbonates, nitrates and acetates of barium have been used to develop high refractive index compositions (1.63) containing a mixture of acrylic acid, methacrylic acid and co-monomers such as hydrocinnamic 10acid, chlorostyrene, styrene and HEMA. A ...
PURPOSE: To obtain a material which has a high refractive index, is excellent in transparencey and can from a transparent coating film layer on a plastic base with sufficient adhesion. ;CONSTITUTION: This material is obtained by hydrolyzing a polymer consisting of repeating units of the formula ...
