The Difference Of Anti Blue Light Lens Or Ordinary Lens?
Anti-blue-ray glasses are glasses that prevent blue light from stimulating the eye.Special anti-blue light glasses can effectively isolate ultraviolet light from radiation and can filter blue light, suitable when watching a computer or TV phone.
Blu-ray damage
1, eye: harmful blue light has extremely high energy, can penetrate the lens to the retina, causing atrophy and even death of retinal pigment epithelial cells.Blue light also causes macular lesions.
2, visual fatigue: Due to the short wavelength of blue light, the focus is not falling at the center of the retina, but a little farther forward from the retina.To see clearly, the eyeball is in tension for a long time, causing visual fatigue.
3, Sleep poorly: blue light inhibits the secretion of melatonin, an important hormone affecting sleep, which is known to promote sleep and regulate time lag.
Difference
(1
The 1, function is different
Anti-blue-ray glasses are glasses that prevent blue light from stimulating the eye.Special anti-blue light glasses can effectively isolate ultraviolet light from radiation and can filter blue light, suitable when watching a computer or TV phone.And ordinary eyes are suitable for usually going out, doing homework and reading to wear.
The 2, has a different effect
(2
Prevent blue light has no effect to prevent myopia, to prevent eye fatigue has a certain effect.But blue light inhibits the secretion of melatonin, an important hormone affecting sleep, known to promote sleep and regulate time lag.Wearing blue-ray glasses before going to bed will not affect the quality of sleep, while regular glasses will.
1, substrate absorption: an anti-blue light element is added to the lens substrate to absorb the harmful blue light in life and achieve the protection purpose of blue light barrier.
2, membrane layer reflection: the lens surface coating, harmful blue light through the membrane layer, to achieve the purpose of blue light barrier protection.
3, substrate absorbs + membrane layer reflection: this technology integrates the advantages of the first two technologies, two-pronged, double-effect protection, this technology is mainly used in the bright moon lens anti-blue-ray glasses.
4, blue light pen uses the blue light pen to illuminate the lens. For non-proof lenses, blue light basically penetrates the lens, while for the anti-blue ray lens, most of the blue light is blocked by the lens.
5, lenses are yellow anti-blue light glasses because they filter harmful blue light, according to the principle of color supplement, the lens will be slightly yellow on the vision.Maintaining a slight color difference and good transmittance and obstructing harmful blue light is the advantage of blue light glasses.
6, lens surface reflection blue light Any anti-blue light lens that uses membrane layer reflection technology, because the lens will reflect harmful blue light, so the lens surface will reflect blue light, and the substrate absorption technology anti-blue light lens will not reflect blue light.
