Product Feature

What Is Blue Light?

    For the purposes of this article, we’ll focus on blue light, one of the many hues in all visible light.

    Blue light is naturally produced by the sun but also by computer monitors, smartphone screens and other digital devices. In addition to these, blue light is produced by LED and fluorescent lights, and compact fluorescent light bulbs. Blue light is essential in maintaining your sleep and wake cycle, mood and keeping your memory sharp.


Harmful Effects Of The Blue Light

    Believe it or not, but today, almost everyone is a victim of Computer Vision Syndrome  (CVS), a condition which results from focusing the eyes on a computer or any gadget for  prolonged hours. Continuous working on digital screens means focusing and refocusing  your eyes back and forth. This leads to eyestrain, dry and sticky eyes. 

The Benefits of Blue Cut Lenses

    Blue Cut Lenses 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.


What Blue Block Lenses by Hongchen Actually Do


1) Anti-glare blue cut lenses protect your  eyes from the harmful effects of blue light  caused by prolonged working hours on a  computer, laptop or mobile.

2) Lower risk of certain types of cancer.

3) Lower risk of Diabetes, Heart Disease &  Obesity.

4)  Make you feel engertic when you finish the  long time working before the computer.

5)Make your eyes turn tried slowly.


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.


    Children are especially vulnerable because their eyes have not yet developed natural defenses against UV and HEV blue light. Today, a staggering 97 percent of American kids under the age of four use mobile devices, and teens are spending an average of 6.5 hours per day on screens. Now that kids are using more digital devices at home and school starting at a young age, it’s important to protect their eyes as much as possible.
