Polymerizable light absorbing azo dyes are disclosed useful as monomers in the formation of devices such as, but not limited to ocular lenses. Specifically, intraocular lenses (IOL) are disclosed wherein one or more of the light absorbing dye is covalently bonded to other structural polymers though ethylene unsaturated groups. The resulting IOLs possess light absorbing properties without significant amounts of free (un-bound) azo dye molecules present in the final structural polymer matrix.
可聚合的吸光偶氮
染料被披露为在形成设备时作为单体有用,这些设备包括但不限于眼镜片。具体地,披露了一种人工晶状体(IOL),其中一个或多个吸光
染料通过
乙烯不饱和基与其他结构聚合物共价结合。由此产生的IOL具有吸光性能,而最终结构聚合物基质中几乎没有自由(未结合)偶氮
