In this guide, we’re going to be giving you a total breakdown of the best way to use blue light glasses. We’re going to combine this with several other things that can help prepare you for a good night’s sleep.

So let’s remove distractions, put on our blue light glasses, and get ready to sleep.

How Do Blue Light Glasses Work?

Before we can explain some rituals and timeframes to prepare you for sleep, it’s important to understand how blue light glasses function. Blue light glasses were created to solve a common modern-day problem.

They are glasses that come with special lenses that have been designed to significantly reduce the quantity of blue light that reaches the eye. 

Blue light is something that you’ll find in many modern electrical appliances including phones, TVs, handheld gaming consoles, laptops, and PCs. Blue light is one of the many different colors in the visible spectrum of light (see also ‘What Color LED Light Helps You Sleep?‘).

Others are red, orange, yellow, green, indigo, and violet. So why is blue light such a problem when it comes to sleep? 

Well, blue light is good for a few things, with recent research suggesting that it can increase alertness, mood, attention span, and reaction times. Whilst all of this is great in the middle of the day, when you need to sleep it’s all the wrong kind of side effects.

This is where blue light glasses come in. They are made to reduce the amount of blue light you’re eyes absorb, allowing you to relax and rewind, and making sure your mind isn’t overstimulated. 

How Long Before Bed Should I Wear Blue Light Glasses? 

There are a few suggestions for how long to wear blue light glasses, and depending on the kind you’ve bought, there is a high chance that they will come with a set of rules and instructions to help you get the best out of them.

Blue light glasses typically block up to 100% of blue and some of green light, which will help you to settle down for sleep. They’re particularly important if you use phones and or other electrical appliances before bed.

Blue light glasses are supposed to be worn 4-2 hours before bed. If you’re able to do this for the time period, then you’ll be able to allow your body to properly decompress.

It’s important to keep them on for this entire time, especially if you’re going to be using any appliances that feature blue light/

Another thing to note here is that you probably shouldn’t use them during the day, and definitely at night whilst driving or doing anything that requires a lot of attention to detail.

We would recommend you wear them for 3 hours before bed, this would be a good sweet spot, especially if you regularly struggle with sleep.

It’s important not to see blue light glasses as a total cure for insomnia or general troubles sleeping. Instead, see them as one tool you have available to help you get into a good sleeping routine.

We’re going to outline some extra ways that you can prepare yourself to sleep, alongside your new blue light glasses.

Blue Light Glasses Routine 

1. Set A Bed Time

The first thing you’re going to want to do is set a bedtime. This doesn’t have to be the exact time that you will sleep (see also ‘Why Does Time Go By So Fast When You Sleep?‘), but it will be the time when you get into bed, turn the lights off, and completely switch your brain off. 

2. Count Back

From here, count back three hours. So let’s say your bedtime is going to be 10:00 PM. At 7:00 PM you will begin your routine. First of all, you’re going to want to put on your blue light glasses and start to turn the lights down around your home. Second, try to use this time to decompress.

3. Avoid Stimulation

From here, you’re going to want to avoid doing anything too stimulating. This is the time for you to wind down. Make sure you don’t remove your glasses unless necessary, and never remove them if you’re going to come in contact with blue light.

4. Avoid Screens

If you can avoid screens, it’s a good idea to do so. We suggest completely avoiding your phone for a whole hour before you sleep if you can. You can always put it in another room if you have a habit of checking it all the time.

5. Settle Down For Bed

Once it’s your bedtime, remove your blue light glasses and settle down into bed. Most people sleep best in the dark and in silence, but you should do what works for you. Give yourself at least an hour or so of relaxing time to allow yourself to sleep.

Eye Disease

Blue light usually penetrates your retina and is thought to lead to degeneration of your cells. This will increase your chances of developing a whole range of eye issues. Minimizing the blue light you’re absorbing can be a good way to solve this problem.

Use Technology In Peace

If you are the kind of person who wants to scroll your phone before you sleep, blue light glasses are a way for you to do this without suffering any negative effects. 

Final Thoughts

Everyone’s bedtime routine is different and it’s best if you pick something that works for you. 

Blue light glasses can be a great addition to your sleep routine, and people all over the world are starting to use them to combat some of the negative aspects of modern technology.

If you struggle with sleep, then there’s a high chance that it has to do with how much blue light you are exposed to.
