Blue light can aggravate macular disease of the retina.
After cataract surgery, blue light can damage the fundus of the eye.
Blue light may cause blurred vision, cause visual fatigue and cause VDT syndrome.
Blue light can inhibit the secretion of melatonin, disrupt sleep, and increase the incidence of major diseases.

LED screen products (such as smart phones, tablets, laptops, TVs, etc.) that have completely penetrated into modern human lives are the source of blue light hazards. Blue light is a serious hazard to human eyes and skin. This is why we must beware of it. At present, the most effective solution is to apply Anti-Blue Light Screen Protector on electronic equipment. The Anti-Blue Light Protective Film technology is very mature and can effectively prevent blue light from penetrating. This is why the use of Anti-Blue Screen Protector is welcome.

Anti-Blue Light Protective Film is a Screen Protective Film developed for blue light radiation. It mainly absorbs and converts blue light by using anti-blue light technology to block blue light, thereby protecting the health of the human body, especially the eyes.
