Do you ever get headaches from staring at a screen all day? I know I do. As a college student, I basically live on my computer. I am always doing work, which is the case for a lot of people. However, staring at a screen all day, especially at night can be harmful for your eyes and your sleep habits. I bought blue light glasses a few years ago and they are so worth it! Let’s break down blue light and talk about how blue light glasses can benefit you!
What is Blue Light
Every color has a different effect on a person. Blue wavelengths are emitted through electronics such as your phone and laptop. Blue light has many benefits during the day, but can actually be harmful at night. During the day, blue light actually makes you more alert and can boost your attention. At night, it can negatively affect your sleep.
How Blue Light Affects Sleep
At night, your body naturally produces melatonin, a chemical that helps you sleep. Blue lights trick your mind into thinking it is still daytime. So, your body won’t produce enough melatonin for you to sleep. Ideally, you should avoid electronics at least an hour before bed, but that’s not always possible. Especially now that it is fall, it gets darker much earlier and you may still be doing work while it’s dark.
Why You Should Use Blue Light Glasses
If you need to be on an electronic before bed, try using blue light glasses. These glasses limit the amount of blue light that is processed by your eyes. It will help your body produce enough melatonin so that when you are done working, you’ll be able to fall asleep easier! Blue light glasses not only help with sleep, but they can always help you avoid headaches from screens at night too!
Blue light glasses are pretty cheap! I got a three pack on Amazon for $12. They are definitely worth it!
