Blue light glasses can be the eye antidote you’ve been missing for a long while now. How so? Well, you’ll see.
Experts place a lot of emphasis on our sleeping routine. This is obviously due to the tremendous impacts of adequate sleep to our mental health. However, for all of the benefits attributed to good sleep, most people are sleep-deprived.
This means, most of us barely get sufficient sleep, which may be the reason for the rapid, faster than normal burnout of our immune system these days. Research has linked this deprivation to blue light emissions. In fact, blue light emissions are key causes of sleep deprivation in over 70% of Americans.
What Are Blue Light Emissions?
Blue light is a high-energy, shortwave, and bright type of light. The wavelengths of blue light typically fall between 420 – 480 nanometers when measured on the spectrum of visible light. As a result of these features, blue light emissions are harmful to good sleep. This is because exposure to the eyes can disrupt the circadian rhythm, which is the internal clock. Disruption to the circadian rhythm leads to irregular and inadequate sleep, thus inducing higher stress levels and migraines.
Blue light is usually emitted by electronics, such as televisions, laptops, computer monitors, smartphones, and tablets. Credible reports have meanwhile revealed that nearly 90% of Americans spend at least 12 of his 24 daily hours on one or two of these gadgets. It’s now pretty easy to see why blue light emissions are leading causes of sleep deprivation in America, isn’t it?
It may interest you to know that blue light has certain benefits. It helps to stay alert and avoid drowsiness, but these are its greatest disadvantages as well.
How Do Blue Light Glasses Work?
Blue light glasses are a new, special type of eyewear that protects the eyes from the harmful effects of blue light by blocking or filtering the emissions of electronics. They work by restricting the harshness of blue light on the eyes while allowing you to work at the same time due to their partially transparent lenses.
Potential Benefits of Blue Light Glasses
The reports on blue light glasses are mixed. Although no one doubts the impacts of blue light on the eyes, research focusing on the effectiveness of blue light glasses is still ongoing. As it stands, these glasses are not approved by the Association of Optometrists in Great Britain and the American Academy of Ophthalmology, with both bodies preferring to be neutral on the issue, perhaps pending the availability of sufficient evidence.
Until then, there is virtually no harm in trying out a pair of blue light glasses. Studies and comments have established that blue light glasses can be beneficial in some aspects. Experts and patients have reported relief or cure from particular issues when they used blue light glasses for a prescribed period. Let’s take a quick look at these reports.
Reduces Eye Blurriness and Strains
There have been several studies on the effects of blue light glasses on eye strains and blurriness, and, luckily, the results have been encouraging. Patients suffering from these issues have often reported improvements upon using these glasses for a while.
In a credible 2019 study, 70% of patients with eye dryness, strains, or blurriness caused by blue light emissions were relieved after wearing blue light glasses for a month. Pretty impressive, isn’t it?
However, note that other factors may cause eye strains and blurriness. A pair of blue light glasses may not work if the condition wasn’t caused by blue light. In such cases, fix an appointment with the doctor on time.
Helps To Avoid Certain Headaches
It is common to feel light-headed after staring at the screen for a long while. On a few occasions, this can persist into a striking headache. Thankfully, you can now put on a pair of blue light glasses while you work on your laptop. The glasses are fashionable and allow clear vision. You, therefore, have no need to worry about looking odd at work.
Credible reports have shown that working with blue light glasses will screen your eyes from the effects of blue light emissions. It’s common logic, isn’t it? You can try one now. You may also want to note that some headaches are not caused by blue light and may be unavoidable with blue light glasses.
Enhances Sleep Habits
Blue light glasses help to avoid specific problems caused by constant exposure to blue light consistently, especially before bedtime, such as blurry vision, migraines, eye strain, and higher cortisol levels due to inadequate sleep. To slightly expand on the last point, research has proven that blue light suppresses the body’s natural secretion of melatonin, which is a hormone that induces sleep.
In research, 60 men with insomnia were grouped into two. Members of group A used stress relievers and wore blue light glasses when using electronics, while the control group used only stress relievers. The results after 30 days were remarkable! Every member of group A reported significant improvement in sleeping habits, specifically stating they could fall asleep more easily now. Members of the control group, on the other hand, couldn’t report the same.
May Prevent Some Eye Diseases
Although still highly debatable and under research, there are suggestions that blue light may slowly damage critical areas of the eyes, particularly the retinas.
Experts, therefore, suggest that you start wearing blue light glasses from now. If studies eventually establish the role of blue light in eye defects, such as glaucoma and macular degeneration, you’d be doing yourself a great service. And if otherwise, you have nothing to lose— these glasses would look cool on you.
Final Lines On Blue Light Glasses
True, blue light glasses are not yet approved by relevant authorities, but we can’t deny their relevance. None of the associations on eye health has disapproved of the use of these glasses; instead, they have remained neutral. The benefits of blue light glasses highlighted above are reported by experts and people who’ve been concerned. You may want to secure your pair as soon as possible.
