technical field

The present application belongs to the technical field of lenses, and in particular relates to an anti-blue, anti-red, anti-purple lens.

Background technique

Long-term exposure to blue light can easily cause eye damage, especially macular degeneration. Blue light can penetrate the lens and reach the retina, causing optical damage to it, accelerating the oxidation of cells in the macular area, producing a large number of free radicals, causing cataracts and macular degeneration. Including: blue light can directly reach the retina, causing myopia; blue light can stimulate brown pigment, which is an important cause of macular and freckles on the skin; blue light can cause fundus damage after cataract surgery; blue light can cause blurred vision, leading to visual fatigue, causing VDT syndrome symptoms; blue light can cause glare.

Infrared rays are thermal radiation with long wavelengths, which are easy to penetrate into the eyes of transparent refractive media, which have no blood vessels, and have poor heat dissipation performance. In addition, the adjacent uvea can absorb a large amount of radiation, so it is more susceptible to damage and lens opacity.

Ultraviolet radiation can cause damage to the eyes and induce skin cancer. Strong ultraviolet radiation can damage eye tissue, cause conjunctivitis, damage the cornea and lens, and is the main cause of cataracts.
