Feeling Blue About Your Lack of Sleep? Blue Light Might Be to Blame

If you’ve recently scrolled on a social media feed, there’s no doubt you’ve seen them.

They are the latest fad in the wellness world. Blue light blocking glasses are (dare I say it?) the new black.

While I am the first one to critique the latest trends, I have to say there is some clout to the blue light blocking fad that seems to have not only taken over the virtual world, but also the real world and my office, in particular.

Those of us who work in front of a computer and use our phones frequently spend an inordinate amount of time staring at a screen. These screens emit blue wavelengths, aka blue light. While blue light itself is not necessarily dangerous, there are downsides to being exposed to it at all hours, specifically those precious hours right before bedtime. In fact, Harvard researchers found that exposure to blue light suppresses melatonin and shifts circadian rhythms in test subjects.

Melatonin is a natural “sleep” hormone your body produces at night. The chemical is released in your bloodstream, and blood levels of melatonin tend to remain elevated for up to 12 hours. This increase will result in a feeling of drowsiness and should assist you in falling asleep and staying asleep at night.

Blue light at night, emitted from your phone or computer, suppresses melatonin. With a reduction in melatonin levels, your ability to fall asleep and stay asleep may be affected. The result? You may feel cranky, sleep deprived and exhausted!

Sleep issues are so prominent and can be detrimental to our health. If there was an easy solution to reducing blue light exposure, wouldn’t you take it?

I certainly would! Hence, I went out and purchased my very first pair of blue light blocking glasses.

I keep my blue light blockers at my desk and put them on anytime I work on the computer. Additionally, I installed a (free!) blue light blocking app on my phone to limit the blue light exposure I receive when I look at that screen (which is more often than I’d like to admit).

As someone who has never had to wear glasses in her life, I was so excited to try on all the different frames and styles of blue light lenses I could get my hands on! Once I found my perfect pair, I couldn’t wait to see if they really made a difference.

Here’s what I noticed: After a few weeks of wearing my glasses, my eyes didn’t feel fried at the end of the work day. I didn’t have that post-work fatigue that encourages an afternoon nap. I noticed a reduction in minor headaches I had been experiencing a few times each month.

As far as my sleeping habits? I have been falling asleep promptly and staying asleep pretty consistently. I wake up in the morning feeling refreshed and ready to get after it!

Overall, I’d say the blue light blocking glasses are definitely worth it. I’ve been using a cheap pair (under $25) and have totally seen results. If not for the known benefits of protecting your eyes and helping you sleep, it’s at least great for the fun of getting to try out cute frames!
