Eyeglasses are essential for anyone with visual problems like astigmatism, myopia, and hyperopia. These lenses correct your eye defects towards a 20/20 vision. A person with this visual acuity has the same average visual capability as another person, normally seeing an object 20 feet away from them without glasses or contact lenses.
In recent years, blue light glasses have become popular among individuals who rely heavily on gadgets. However, as the question of whether these spectacles work remains, here are a few known benefits to help you decide if you should get one for yourself:
Blue Light is Everywhere Around You
Due to the COVID-19 pandemic, online classes and work-from-home setups have raised awareness and concerns about blue-light emitting products. Furthermore, everyone was exposed to blue light even before the pandemic.
As the sun’s energy recipient, the world is full of electromagnetic energy. But unfortunately, the blue wavelength is one of the few visible light spectrums to the naked eye.
In addition, the screens on devices such as laptops, smartphones, and televisions produce blue light due to the light-emitting diode (LED) technology. Furthermore, the pandemic increased people’s need and duration to use and stay in front of these devices.
They Can Help Lessen Eyestrain
Although eye doctors agree that more research is needed about long-term blue light effects, they also agree that wearing blue light glasses all day won’t cause any harm.
Optometrists weren’t against their patients who chose to purchase these spectacles. Furthermore, some clients have also reported less eyestrain after wearing the glasses.
Consumers have proven, in a way, that blue-light filtering glasses can reduce the symptoms leading to computer vision syndrome (CVS).
This eye problem occurs from too much eye movement and irritation from reading on a scrolling screen. Headaches can also be a symptom of other concerns, such as eyestrain. And they can be triggered and exacerbated by light and can lead to migraines.
Wearing glasses with blue-light blocking lenses can prevent headaches and other symptoms altogether. In addition, they can help your eyes focus, thus leading to less eye fatigue and strain.
They Can Help You Sleep Better
A 2017 study found that wearing blue-light-filtering glasses increases melatonin. This finding coincides with the argument that blue light increases the body’s alertness.
Due to its high energy frequency, being exposed to the blue wavelength tricks your body into thinking that it still needs to be alert instead of resting. Thus, it delays the release of the sleep-inducing hormone melatonin, which your body desperately needs for a night of deep and fulfilling sleep.
These are perfect for students or workers who constantly burn the midnight oil. So, you can work late at night but still get some quality sleep after.
Additional Need-to-Knows
The key to fewer eye problems is less exposure to blue-light emitting devices. So, try to limit your use and take a breather from technology from time to time. But, of course, it is ideal for you to put your devices away when not of utmost need.
On the other hand, the world now relies enormously on gadgets and technology, so staying away from them might not be negotiable.
Practicing looking at an object 20 feet away from you for 20 seconds after using a device for 20 minutes or the 20-20-20 rule instead would be beneficial. And again, using blue-light filtering spectacles can also help.
