Blue light blocking glasses aren’t as common as sunglasses. People who aren’t familiar may mistake the glass for prescription glasses. In this article, we’ll try to clear the air about blue light glasses. We shall get to know them briefly and also talk about the benefits of wearing them.
Intro to Blue Light
Basically, a blue light blocking glass is used to block blue light that one encounters in artificial lighting conditions or during night. These glasses are available in different varieties – including glasses for kids, budget options, and also some premium variants.
Not many know that artificial light can seriously impact a human body in multiple ways. Quite a few decades ago, most people woke up to sunlight and rested when the sun set. They were not using artificial lights to extend their awake hours. Things have considerably changed today. Artificial lighting, such as those from electronics, could suppress melatonin production and disrupt circadian rhythm. Computers, phones, TVs and tablet PCs emit high levels of blue light.
However, blue light is not all that bad. In fact, blue light from the sun during the day helps maintain correct circadian rhythm. It’s only during night that blue light poses issues. After dawn, the blue night tells the body it’s still daytime, which can hamper body biology.
Advantages of Impeding Blue Light During Night
• Eye Protection
Blue light-blocking glasses benefits are huge and varied. The primary positive is prevention of DHA essential fat damage. The essential fat lies in the retinal pigmented epithelium. The fat helps convert sunlight into necessary DC electric current the body requires.
• Melatonin Production
Blue light during night suppresses melatonin production in the body. Also, it indicates night owls and shift workers could maybe safeguard themselves if they put on eyeglasses that blocked blue light.
• Cortisol Patterns
A big difference is usually noticeable in cortisol patterns and sleep when you wear these glasses at night regularly. When you stay away from blue light during night, the salivary cortisol patterns drastically improve.
• Assistance for Shift Employees
Shift employees are usually at a higher risk for disruptions in circadian rhythm due to their non-conventional schedules. Generally, these people have more health issues than people who work regular hours. A study put a few night shift workers through a test to determine the efficacy of blue light blocking glasses on their health. After the study, the workers’ sleep quantity increased, along with their sleep efficiency.
• Mitochondria Assistance
Some evidence point out to blue light’s ability to augment the proteins’ distance in mitochondria’s respiratory electron transfer chain. This reduces their ability to produce mitochondria.
