CONTACT LENS AND CONTACT LENS PRODUCT
A contact lens includes at least one color changeable region, wherein the color changeable region includes at least one photoluminescence material. When a wavelength of the photoluminescence material having a maximum radiation intensity is WEmMx, an average transmittance in a wavelength range of 400 nm-700 nm of the color changeable region is T4070, a size of a total area of the color changeable region is AC, and a size of a total area of the contact lens is AL, certain conditions relating to WEmMx, T4070 and AC/AL are satisfied.
Multimeric protected fluorescent reagents
Multimeric protected fluorescent reagents and their methods of synthesis are provided. The reagents are useful in various fluorescence-based analytical methods, including the analysis of highly multiplexed optical reactions in large numbers at high densities, such as single molecule real time nucleic acid sequencing reactions. The reagents contain fluorescent dye elements, that allow the compounds to be detected with high sensitivity at desirable wavelengths, binding elements, that allow the compounds to be recognized specifically by target biomolecules, and protective shield elements, that decrease undesirable contacts between the fluorescent dye elements and the bound target biomolecules and that therefore decrease photodamage of the bound target biomolecules by the fluorescent dye elements. The reagents also contain coupling elements connect monomeric compounds into multimeric forms, thereby increasing brightness.
