There is a rise in the popularity of wearing blue light glasses. This type of eyeglasses claims that it can filter out blue light produced from computers, tablets and smartphones. There had been numerous advertisements about blue light glasses that say that blue light overexposure can cause several problems. To name a few of the issues that are usually linked to overexposure to blue light are dry eyes, disruption in the sleep cycle and macular degeneration (this typically cause for some people to lose their central vision).
What are Blue Light glasses?
Blue light glasses have started to get a fair amount of attention recently because unlike braces for
crooked teeth and some of the other unappealing ways we care for our bodies, blue light glasses are fashionable and cool.
Blue light glasses generally look just like standard prescription glasses, however with one big difference: the lenses are specifically designed to block out the blue light (or even UV light) from getting through to your eye. If you are fond of looking at a digital screen, particularly after dark, using these glasses can help to minimize exposure to the blue light waves.
What is blue light?
Blue light is the shortest luminous wavelength on the visible light spectrum, and it is almost everywhere. Sunlight produces blue light along with many other visible light wavelengths, and both energy-efficient and digital lighting also produce high amounts of blue light. There is no adverse effect when exposed to blue light at a minimal level. However, most of us are absorbing way too much blue light due to our daily access to digital screens and bright nighttime environments. According to the experts, blue light tends to disrupt your sleep and circadian rhythm.
Studies have found that the blue light actively interrupts the development of melatonin, a hormone that is a central regulator of circadian rhythms and is also essential for sleep. It also claims that blue light restricts melatonin more than twice as long as other visible wavelengths of light and changes circadian patterns twice as often.
Room light, which is rich in blue wavelength light from high-efficiency light sources, also inhibits
melatonin. When blue light suppresses melatonin, it also increases cortisol development (the stress and sleep-interfering hormone).
Blue light exposure reduces sleep time and contributes to more nighttime awakenings leading in less relaxing sleep and more tiredness the next day.
Some important recent studies show that blue light in our eyes could cause unusual harm to the cells. Research shows that blue light has a remarkable potential to affect our eyes’ health and development, raising the danger of eye disorders such as cataracts and macular degeneration associated with age. (Poor sleep alone, as research indicates, can also lead to visual impairment.)
There is also a a published study that too much exposure to blue light can add a high risk of developing some diseases such as cancer, including breast and prostate cancers. There is also a developmental link between exposure to blue light and obesity and even diabetes.
Exposure to blue light is not just an adult issue since we all know that children also tend to spend
much of their time looking at smartphones or tablets, thus overexposing them to blue light as well. Study finds that exposure to blue light at night causes children to develop less melatonin in their bodies and to feel less relaxed during bedtime.
The good news is that there is an emerging and growing body of research that demonstrates that blue light glasses can be remarkably efficient in screening out blue light and restoring good sleep and biorhythms.
When will we become vulnerable to HEV or blue light?
We know the perils of exposure to sunlight. That beautiful warm sunny day most of us enjoy is the main factor in exposure to blue light. However, even those who may prefer to remain inside the house just watching television or playing video games are still not guaranteed that they are free from exposing themselves from the blue light. This is mainly because smartphones, TVs, computer screens, and artificial lighting also exposes us to “unnatural” blue light. While our electronic devices emit just a fraction of the HEV light emitted from the sun, the amount of time we expend using our devices will affect our health both immediately and cumulatively.
Is there a need to worry about overexposure to blue light?
The straightforward answer is yes. Blue light is just like salt; it is necessary for our body, but too much salt will cause harmful effects on our body. And while being in a digital age where almost everything revolves around computers, smartphones and tablets that can help us with our everyday life, it has overexposed us to blue light. Fortunately, blue light glasses had been invented, and it has significantly reduced the danger of overexposure.
What are the benefits of Blue Light Glasses?
Many of us probably heard of blue light glasses that are among the most effective solutions for reducing the harmful effect of the blue light. Blue light is nearly anywhere from LED lights to our smartphone screen and even the sun there is no escape from the blue light in our everyday life. Although exposure to blue light is not fatal, limiting your exposure will help you get better sleep, mitigate eye strain and retain your circadian rhythm running efficiently, particularly in the hours before you go to sleep.
There are many benefits to wearing blue light glasses. These glasses could be used to lessen the impact of blue light on your eyes at work, throughout the day and particularly before bedtime. When you are having eye strain or a bad night’s sleep, you must bear in mind that a variety of reasons may affect this. Blue light glasses will certainly help, although it may not be the ultimate solution.
Blue light glasses contain a specially designed lens built to block or filter out of digital screens that the blue light emitted off. The lenses appear to shield your eyes from radiation and may help minimize possible harm to your retina from excessive exposure to the blue light.
