If you’re planning on getting a pair of glasses to protect your eyes from radiation from the notorious blue light, read on. In this article, we’ll answer this question: Is using anti-radiation glasses effective?
Blue Light and Computer Radiation, Explained
While “blue light” is a relatively new term, computer radiation is not. In fact, the issue of computer radiation had already inspired many researchers to find out just how much radiation comes from our screens. What exactly is computer radiation, and how is it different from blue light?
Radiation is a form of energy coming from both visible and invisible light. Visible lights are those with colors red, orange, yellow, green, and blue. Note that warmer colors, like red light, have lower energy, while cooler colors, such as blue light, have more radiation.
And then, of course, there’s the invisible light, which is composed of ultraviolet rays. UV lights have the highest energy or radiation and can lead to health risks such as sunburn, skin cancer, and eye diseases (depending on exposure).
Here’s the thing: the blue light emitted by our digital screens is the closest to the UV rays. This means that next to UV rays, blue light produces the highest radiation. Due to this, many people believe that using anti-radiation glasses is an effective way to protect the eyes while using gadgets. But are anti-radiation glasses effective? Read on to find out.
Should You Worry About Computer Radiation and Blue Light?
Devices do emit radiation, but it doesn’t carry enough energy to pose health risks. Moreover, at least one study found out that electronic gadgets do not emit the dangerous ultraviolet rays.
But, what about the blue light?
The American Academy of Ophthalmology points out that there’s no evidence that blue light from digital screens causes eye damage. If you’re feeling some eye discomforts, like blurry vision and tired, achy eyes, it’s probably because of prolonged gadget use. Experts say that when we use our screens, we blink less often. This may lead to eye strain and dry eyes.
Here’s a gentle reminder: although there’s no scientific evidence that blue light damages the eyes, studies have shown that it can affect our sleep-wake cycle. Suffice to say, if we use gadgets close to our bedtime, the blue light may keep us from falling asleep.
Are Blue Light Glasses Worth It?
Blue light glasses supposedly work by blocking the blue light emitted by our devices. However, since there’s no scientific data that blue light damages the eyes, The American Academy of Ophthalmology says that we don’t need them. In fact, they do not recommend any special glasses for computer users.
