Learn the pros and cons of Blue Light
Posted: Sep 28, 2019
From LED lights to computers and smartphones to the sun, blue light follows us everywhere we go.
Blue light is one of the most efficient and highest-energy wavelengths within the light spectrum. High efficiency and low cost make it the leading wavelength for all electronic devices/digital screens. Blue light emitted from the digital screen is also known as artificial light. Its development allows users to work longer, sleep later and facilitates their 24-hour entertainment culture. So, there is nothing wrong to say that these rays are deeply ingrained in our daily lives. Some studies warn against the harmful effects of overexposure to these harmful rays, while some show a more optimistic approach.
Let’s take a look at both potentially positive and negative health effects of excess blue light.
Blue Light Pros
Even the most efficient bulb or computer screens emit a high amount of blue light. The blue rays from natural sunlight can have a positive effect on your health as they come with the full light spectrum. Natural rays from the sun are especially essential for controlling your circadian rhythm- body’s asleep-awake cycle. In addition, when you are exposed to it during the day, it gives positive results to your Suprachiasmatic Nucleus (SCN) - a little part of your brain that works as the master alarm clock of your body. It helps you sleep better, keep you alert, wake up relaxed and even increase your hormone levels and immune system.
Blue Light Cons
Some exposure to blue light during the day is good for health. But, on the other hand, overexposure to it is bad for your health. You live in a blue-lit world where your electronic devices and digital screens strike you and your close ones with a blue light at all hours. And human bodies are not designed for being exposed to round-the-clock blue light. Exposure to blue light from a digital screen at night affects your body’s natural cycle. That’s why staring at digital screens right before bedtime can make it harder to sleep. When you stare at a bright screen in the dark before bedtime, it decreases your melatonin levels – a hormone that maintains your sleep-wake cycle.
Many people don’t get enough sleep and have no idea that artificial rays are one of the biggest hurdles to their restful sleep. This light also leads to eye-strain, vision loss, migraine and other eye-related illnesses such as macular degeneration.
How to limit blue light’s dark side?
When it comes to reducing the negative effects of blue light, blue blockers are the best way to go. By wearing them at least three hours before going to bed, you can protect your eyes from harmful rays that alters your sleep-wake cycle. This means they can increase your melatonin levels, resulting in improved sleep, health, and productivity.
As you can see, the blue light can be both good and bad for your health. However, you can also eliminate its negative effects by wearing blue light blocking glasses. So, what are you waiting for? Just purchase a pair of these glasses and get improved sleep, perfect vision, and increased alertness.
Blue light blocking glasses block ALL blue light — including healthy amounts, and distort your color perception.
