The present invention provides a kind of optics polymerisable compound, optical composition, large area window, polyisocyanate composition, eyeglass and its manufacturing method, wherein the optics polymerisable compound is made of poly-thiol compound and polyisocyanate compounds, the specific gravity of carbamate system optical lens for reacting these compounds and obtaining is low, therefore light and heat resistance is outstanding, the decline of the impact resistance after especially solving the problems, such as hard multi-layer coating.The lens manufactured using the polymeric compositions include that a variety of optical characteristics such as workability, the transparencys such as formability and dyeability are outstanding. |
