Are musicians the only one who can wear tinted glasses inside even at night? No! In fact, after knowing why you should be wearing blue light blocking glasses, you will say everyone should start wearing them immediately.
Blue light blocking glasses, as the name implies, are designed for blocking blue light most people encounter when it’s dark outside. Their function is the reverse of sunglasses. You are supposed to wear them indoors for blocking artificial light.
These glasses are not expensive. If you can afford the smart home technology, then you can afford them as well. These are equally essential! Here is what Harvard has to say about blue light.
All kinds of artificial lights have the ability to suppress the release of melatonin. The blue light, on the other hand, does that more powerfully. Researchers at Harvard conducted an experiment to compare the effects of exposure of blue light (for 6.5 hours) and green light. The blue light suppressed melatonin twice as long as the green light. This is alarming!
The following reasons further explain why you must wear it:
1: Better Sleep
Artificial lights can mess with circadian rhythm and disturb the sleep cycle. Those who work for the night shift are at a higher risk of developing cancer. Even recreational exposure to blue light is harmful.
It is not just the shift workers, but anyone who is up after dark and looking at sources of blue light such as computer or TV is at risk. Wearing blue light protection glasses you will fall asleep fast.
2: Eye Protection
It can prevent the damage to DHA essential fat present in the retina. The pigment present inside the retina is responsible for converting sunlight into DC electric current that is required by the human body.
3: Control the Release of Cortisol
Cortisol is another hormone in the human body that is responsible for regulating blood pressure and blood sugar. It is also called the stress hormone as the more it’s released, the more stress you experience.
It’s released in the morning the most followed by the day and night on various levels. The relationship between blue light and cortisol is complex. However, experts suggest that when you are exposed to blue light in the dark, it increases the release of cortisol. That might be one reason you are stressed out.
4: Regulate the Production of Melatonin
Speaking of hormones, how can we forget melatonin? It is responsible for controlling the circadian rhythm of the body. The level of melatonin is higher throughout the night. As you are exposed to daylight, the level falls down. It helps us stay active and awake.
When artificial light interfaces with natural light, it suppresses the production of melatonin. It can hence disrupt the circadian rhythm in an individual. If you work during night shifts, it’s better to wear light blocking glasses to stay safe.
5: Reduced Risk of Serious Illnesses
Exposure to blue light can cause serious health issues such as diabetes, depress, obesity, heart diseases, and even cancer. When the melatonin level in the body is messed up, it can become a cause of developing cancer. As the circadian rhythm in a person is altered, it can cause blood sugar to rise. It’s best to wear this glasses at night to keep away from developing such illnesses.
6: Treat Mania
Bipolar patients often experience emotional highs or extreme moods known as mania. When these patients wear blue light glasses, it can improve their sleep pattern and reduce the symptoms of mania.
