Digital Screen Protection: Blue Light Lenses


Due to the coronavirus pandemic, millions of people worldwide now spend most of their time indoors. If you’ve been working from home or attending classes remotely, you must have observed how staring at your computer for long periods causes a wide range of discomfort. Your eyes twitch, and your vision becomes blurry. You also experience red, dry, itchy eyes, headaches, and even neck and shoulder pain. All of these unwanted symptoms indicate digital eyestrain.

 

What Is Blue Light and How Does It Affect You

 

Blue light is the high-energy, short-wavelength light that’s part of the visible light spectrum. It helps elevate mood, boost alertness, and regulate your body’s natural wake and sleep cycle. It’s primarily emitted by the sunlight. But you can also be exposed to blue light from artificial sources. These include fluorescent light, light-emitting diode (LED) light or television, and electronic devices, such as smartphones, tablets, and computers.

 

How Blue Light-Filtering Technology Helps

 

While it’s true that your body needs blue light to keep you sharp during the day, too much exposure can cause digital eyestrain. There is still a lot that needs to be explored about how blue light affects eye health. Nevertheless, blue light lenses have been associated with two potential benefits. These are reduced digital eyestrain and improved sleep. Blue light lenses can:

 

·       Protect You From Digital Eyestrain. Humans blink approximately 15 times every 60 seconds. But this rate can be reduced to half when you’re using your digital devices. Upon penetrating your eyes, the blue light scatters. As a result, your eyes work harder to adjust to that scattered light and focus on objects. Since your eyes are putting in more work as you work on your computer, you experience dry eyes, burning sensation, and blurred vision.

 

·       Keep Your Sleep From Getting Disturbed. Research shows that exposure to blue light can suppress the body’s natural production of melatonin. This is a hormone that has sleep-inducing effects. That’s why it’s believed that overexposure to blue light can keep you up. Whenever you check your news feed, play video games, or binge-watch Netflix shows late into the night, you’re signaling your brain to stay awake. Studies suggest that wearing blue light lenses a few hours before bedtime can result in better and more restful sleep.

 

How Blue Light Lenses Work

 

Blue light lenses are designed to block blue light from reaching your eyes. The blue light-filtering technology uses a special coating to reflect a percentage of this harmful light away from your eyes. How high the percentage of blue light your lenses can block largely depends on the kind of eyewear you use. There are blue light lenses that look clear. Other eyeglasses have a yellow tint to it. The blue light lenses that are more yellowed appear to filter more light than the clearer ones. Other lens designs have added features, including anti-scratch, anti-glare, and ultraviolet light filter.
