Abstract

The invention discloses a medical multifunctional goggle lens, and belongs to the field of protective lenses. The medical multifunctional goggle lens comprises a substrate and a surface membrane layer; the substrate is formed by mixing and injection molding from the following components in parts by mass: 960-1000 parts of organic high-molecular polymers, 30-40 parts of additives, 10-15 parts of ultraviolet ray absorbents and 3-5 parts of short-wave visible light absorbents; the surface membrane layer comprises an intensifying layer, a refraction layer and a waterproof layer which are sequentially compounded on the substrate from inside to outside. The invention also discloses a manufacturing method of the medical multifunctional goggle lens. The goggle lens provided by the invention can effectively filter ultraviolet rays, purple light and blue light, can prevent injury caused by blue light, is especially suitable for protecting harmful light radiation to eye patients after operation and eye disease patients, and is also suitable for preventing eye diseases caused by harmful light for medical staff and normal people.

Description

technical field [0001] The invention relates to a lens and a manufacturing method thereof, more specifically, to a medical multifunctional goggle lens and a manufacturing method thereof. Background technique [0002] It is well known that ultraviolet rays are highly destructive to human eye cells. Ultraviolet rays have direct damage to the structures of the cornea, natural lens and retina of the eye. Eyes exposed to ultraviolet rays for a long time are prone to cataracts, causing direct damage to the retinal pigment epithelium and causing and accelerating age-related maculopathy. [0003] In recent years, through medical research and experiments, it has been found that not only ultraviolet rays have a great harmful effect on human eyes, but also short-wave light with a wavelength of 380nm to 500nm of visible light also has a considerable harmful effect on human eyes. Violet light and blue light with wavelengths have limited color resolution, and are not sensitive to visual...
