Fashion Metal Frame Mens Anti-blue Ray Computer Glasses

Aniti-Blue ray glasses are glasses that prevent blue light from irritating your eyes. Special anti-blue glasses can effectively isolate UV and radiation and filter blue light, suitable for use when watching computer or TV mobile phone. Try using these glasses to protect your eyes if you use your phone or computer for a long time.
Blue light is part of the natural visible light, which is emitted by sunlight and electronic screens. Blue light is an important part of visible light, nature itself does not have a separate white light, blue light and green light, red light after mixing white light. Green light and red light have less energy, less stimulation to the eye, blue light waves are short, high energy, can directly penetrate the lens to the macular area of the eye, resulting in macular disease.
As early as 1966, Nell et al. found that exposure to blue light could cause damage to retinal cells, resulting in decreased or even lost vision. Among them, the short-wave blue light with a wavelength between 400 and 450 nanometers is the most harmful to the retina.
At the 2010 Annual meeting of the International Optical Association, the world's top optical experts unanimously pointed out that short-wave blue light has extremely high energy and can penetrate the lens to the retina. Blue light irradiation of the retina will produce free radicals, and these free radicals will lead to the death of retinal pigment epithelial cells, the death of epithelial cells will lead to the lack of nutrients in light-sensitive cells and cause vision damage, and these damages are irreversible.
German ophthalmologist Professor R.H.W. Funk's research report pointed out that when the "inappropriate light" is constantly shining into our eyes, it can also cause physical dysfunction.
