Description
Technical Field
The utility model belongs to compound lens field especially relates to a high non-light tight lens.
Background
The blue light refers to high-energy visible light with the wavelength of 400-500 nm. The light has various damages and influences on human eyes, and because the short-wave blue light has extremely high energy and can penetrate through crystalline lens to reach retina, the harm of the blue light radiation is mainly reflected in the following aspects: (1) the blue light irradiates the retina to generate free radicals, and the free radicals can cause the retinal pigment epithelial cells to die, the die of the epithelial cells can cause the light-sensitive cells to lack nutrients so as to cause visual impairment, and the macular degeneration of the retina is very easy to cause, and the macular degeneration almost becomes the first killer of the global human vision. (2) After the blue light is emitted into the fundus and focused, the focal point does not fall on the retina, but falls between the retina and the crystalline lens, so that the chromatic aberration distance of the light in the eye is increased, and the distance between the focal points in the eye is the main reason for forming blurred vision, so that the blue light can aggravate chromatic aberration and blurred vision, when the eye muscle is excessively tensed, the blood supply of the eye is excessively tensed, and the blood supply of the eye is strengthened, so that the fatigue is aggravated. (3) The intensity of blue light emitted by LED lamps, computers, mobile phones and the like which are commonly used in daily life is close to that of blue light in noon sunlight, and the inside glasses are very close, at the moment, the damage of the blue light to a retina and the influence on melatonin secretion far exceed the irradiation intensity of 1.3 lux blue light, and as the blue light stimulates the brain, the melatonin secretion is inhibited, the generation of adrenocortical hormone is improved, so that the hormone secretion balance is damaged, and the sleep quality is directly influenced. Research shows that a great deal of blue light exists in LED lamps, computer monitors, mobile phones, digital products, liquid crystal display screens, bath heaters and other light rays. In order to prevent the almost ubiquitous blue light damage, the development of blue light protection glasses with a real blue light prevention effect is urgently needed.
