In recent years, more and more of our time is spent staring at screens. Our TVs, our phones, even our watches all contain digital screens. These screens, while useful, also contain blue light—a type of light emitted by LEDs and electronic screens. While exposure to blue light is completely normal, overexposure can have consequences on our health, specifically in regard to sleep and eye strain.
Thankfully, there are ways to prevent this with blue light blocking glasses. Here are just some of the benefits these glasses can bring:
They relieve eye strain
Have you ever stared at a computer screen for too long and notice that your eyes are dry and tired? This is a sign of eye strain, and it is typically caused by the blue light from our screens. Blue light blocking glasses, however, prevent that blue light from reaching your eyes. In turn, it reduces eye strain if you’re staring at a screen for prolonged period of time.
It’s great for remote work and remote learning
Due to the coronavirus, more and more Americans are working or learning from home. However, this also means that we are even more reliant on our digital devices to connect with co-workers or to participate in class. Increased screen usage can result in eye strain (see above), but this can be avoided by wearing blue light blocking glasses while you work.
Blue light blocking glasses can help you sleep better
Increased exposure to blue light won’t just strain your eyes—it can also adversely affect your sleep. Our circadian rhythms depend on our melatonin levels, which is directly impacted by light exposure. So, as the sun rises, our melatonin levels increase, and we become more awake. However, as the sun sets, our melatonin levels decrease, and our body signals it’s time for bed. If we increase the amount of light we receive at night, then, our melatonin levels remain high and it becomes more difficult for us to fall asleep.
