With the increasing use of electronic devices such as smartphones, computers, and tablets, many people are experiencing eye strain and headaches due to prolonged exposure to the blue light these gadgets emit. In fact, a study states that around 60 million people globally suffer from computer vision syndrome (CVS), which is primarily caused by the said harmful light. As a result, there has been significant demand for protective solutions. Chief among these are blue light glasses.Interestingly, while blue light glasses primarily aim to alleviate these eye-related issues, they also provide a wide range of wearer benefits that not a lot of people are aware of.
How do blue light glasses work?
The primary purpose of these specialized glasses is to effectively reduce the amount of high-energy blue-violet light that reaches the eyes. To accomplish this, one method utilized by blue light glasses is the application of special coatings on the lenses to absorb said light. Additionally, another method is the incorporation of yellow or amber tint into the lenses. When applied to lenses, colors such as these selectively filter out blue light while allowing other wavelengths of light to pass through for visual acuity.Some blue light glasses may use a combination of both methods to provide comprehensive protection and maximum reduction of blue light exposure. In addition, many blue light glasses have evolved from simple blue light filtering to incorporating other protective properties such as UV protection, which is a common characteristic found in sunglasses. This has further boosted the usefulness of this eyewear. In line with this, here are other additional benefits you may not have expected from blue light glasses.
Better sleep quality
Some of the negative effects of blue light include how it disrupts the natural circadian rhythm, which is essentially the body's internal clock. This happens due to the harmful light's suppression of melatonin production. Melatonin is a hormone that causes us to feel drowsy and is crucial for regulating sleep and wake cycles. Suppressed melatonin production, particularly in the evening, makes it much more difficult for individuals to fall asleep, let alone achieve restful sleep. It also makes them more susceptible to developing insomnia. By minimizing exposure to blue light through the use of glasses, the body can continue producing melatonin as it naturally would. This greatly improves sleep quality and allows one to fall asleep quicker and more deeply.
Improved focus and concentration
When individuals are exposed to excessive amounts of blue light, their eyes have to work harder to maintain focus, leading to eye fatigue and decreased concentration. By wearing blue light glasses to block this harmful light out, the eyes are able to relax even while working and being exposed to screens. This allows individuals to better engage in tasks and activities that require sustained attention and mental acuity. Given blue light glasses' positive effects on sleep quality, they also naturally lead to increased alertness and focus during the day.
Positive impact on mental health
Both lack of proper sleep and physical discomforts, such as eye strain, are factors that can have a significant impact on mental health. Over time, this can increase the risk of anxiety, depression, and mood swings. Additionally, blue light is said to impact the body's production of mood-regulating hormones like serotonin and dopamine.Fortunately, considering both aforementioned points, blue light glasses also positively impact overall mood, cognitive function, and mental health. With better sleep hygiene comes a stark decline in depressive symptoms. At the same time, having less pain and discomfort can significantly improve the quality of life, which colors many people's mental well-being. In addition to all the direct and practical benefits, blue light glasses can also provide individuals with a sense of control over their environment and well-being. In a world where people are constantly surrounded by screens and technology, it can be empowering to take proactive steps to protect personal health. Wearing blue light glasses is a simple and effective way to do just that, allowing individuals to feel more in control of their exposure to blue light and its potential impact on their mental health.For more on the different benefits that various everyday items and activities can bring, be sure to check out the rest of our blog.
