If you work on a computer, use a smartphone, watch TV, or simply go out in the sun, you are being exposed to high-energy visible (HEV) blue light. Too much blue light exposure can damage the eyes over time and even lead to vision loss. Today, more people are wearing blue-light-blocking lenses to protect their eyes from these potentially damaging rays.
1) The Dark Side of Blue Light
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.
2) The children need pay more attention to the blue light.
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.
3) How to protect yourself from the blue light?
The good news is that scientists have created an affordable coating for eyeglasses that helps block blue light. If you work on a computer all day, you look at a digital screens in the evening, or your job requires you to work second or third shifts, we have eyeglasses that can help block blue light so you can protect your circadian rhythms and ultimately your health.
4) What blue cut lens to protect our eyes?
The blue cutl enses cut down the harmful UV rays completely along with a major portion of HEV blue light, protecting our eyes and the body from potential danger. These lenses offer sharper vision and reduce the symptoms of eyestrain that are caused by a prolonged computer exposure. Also, the contrast is improved when this special blue coating reduces screen brightness so that our eyes face minimum stress when exposed to blue light.
5) Today's life need the blue cut lens.
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. But, no matter how much you are used to a modern lifestyle and how much you enjoy working on laptops, tablets, mobiles and computers, it poses a threat to your eyes. Hence, it is recommended to use lenses with blue cut filter coating for a comfortable vision.
