摘要:
Described are ocular devices such as intraocular lens preferably made of an organic polymeric material and an ultraviolet light absorber coated with a polarizing polymer component adjacent the edge thereof. A typical polarizing component is polyvinyl alcohol doped with iodine (PVA/I2). The ocular device with an added polarizing component is capable of absorbing light parallel to the axis of the polymer chain, while transmitting light that is perpendicular to the axis of the polymer chains. The polarizing component will reduce polarized light radiating off of horizontal surfaces; therefore, the film will improve vision through the device by reducing glare from light sources.
