HOW HARMFUL IS BLUE LIGHT TO THE EYES

    Often working at computer? Often playing with mobile phones? Often playing video games? Have you ever had eye fatigue and can't sleep at night? Are you being hurt by blue light? Our eyes are indispensable organs of the body. To protect them is to cherish life. You have to take a moment to understand what blue light is and how to protect your eyes from blue light.

    Blue light is part of natural visible light, and both sunlight and electronic screens emit blue light. Blue light is an important part of visible light. Nature itself does not have a single white light. Blue light mixes with green light and red light and shows white light. Green light and red light have less energy and cause less eye stimulation. But the short blue light has high energy, which can directly penetrate the lens to the macular area of the eye, leading to macular lesions. As early as 1966, Nell et al. found that blue light irradiation can cause damage to retinal cells, leading to visual impairment or even loss. Furthermore, short-wave blue light between 400-450 nanometers is the most harmful to the retina.
At the 2010 annual meeting of the International Association of Light, the world's leading optical experts unanimously pointed out that short-wave blue light has extremely high energy and can penetrate the lens directly to the retina. The free radicals will be produced when blue light irradiate to the retina, which can cause retinal pigment epithelial cells to decay. The decay of epithelial cells can lead to visual impairment for lacking of nutrients in photosensitive cells, and these impairments are irreversible.
    Generally speaking, the harms of blue light to human body are as follows: 1.Damage to eyes 2. Eyes fatigue 3. Sleep poorly


    It’s time to wear a pair of blue-blocking glasses. Voogueme website is promoting Christmas sale with a 20% discount on blue-blocking lenses. You can grab this chance and place an order with blue-blocking glasses.

    Blue-blocking lenses can effectively reduce the persistent damage of blue light to eyes. With blue-blocking lenses, the intensity of blue light emitted from mobile screen has been effectively suppressed, and the harm of blue light to eyes has been reduced.
    Because of filtering harmful blue light, according to the principle of complementary color blue-blocking lenses will show slightly yellow in vision.


    Blue-blocking glasses are suitable for the use of LED digital display devices such as TV, computers, PAD and mobile phones. But in daily life, it is not recommended to wear for a long time, because the lenses filter part of the blue light, and the picture will show slightly yellow when viewing. It is recommended to wear two pairs of glasses, one pair of ordinary glasses for daily use, and one pair of blue-blocking glasses for using computer and other LED display devices. Blue-blocking glasses with no RX are very popular with non-myopic users. They are specially used in computer office wear, and gradually become a fashion.
