Why we need the blue cut lens?
The most common effects of too much blue light exposure are eye strain, blurred vision, and headaches. However, recent studies have focused on blue light’s negative impact on the circadian rhythm and found that watching TV or using a tablet before bedtime, for example, can result in restlessness and disrupted sleep cycles. In extreme cases, too much blue light exposure can even lead to permanent eye damage and vision loss.
Blue cut lens can help you
Blue Cut Lens is to block and protect your eyes from high energy blue light exposure. Blue cut lens effectively blocks 100% UV and 40% of the blue light, reduces the incidence of retinopathy and provides improved visual performance and eye protection, allowing wearers to enjoy the added benefit of clearer and sharper vision, without altering or distorting color perception. Blue light lens is ideal for people who work on digital devices for prolonged hours. By restricting the blue light from entering into the eyes, it helps reduce the symptoms of eyestrain (dry and sticky eyes) resulting from screens of digital devices. Also, lenses with blue cut coating offer a comfortable vision and may improve visual performance in low color contrast.
The Coating of Lens
Hard Coating: The hard coating can help the lenses be destoried.
AR Coating: It means coat another anti-reflective coating on the hard coating . It can perfectly reduce harmful ray and enhance the vision effect.
