It is becoming increasingly common that people are finding it difficult to fall asleep at night. One of the reasons for this is our exposure to blue light and its effect on our circadian rhythm. Here we explore how blue light affects sleeping patterns.

To understand how blue light affects sleeping patterns the first thing to mention is the Circadian rhythm. Circadian rhythms are 24-hour cycles that are part of the body’s internal clock. One of the most important and well-known circadian rhythms is the sleep-wake cycle. When working correctly, a circadian rhythm allows for consistent and restorative sleep. But when thrown off, it can cause sleeping problems. They are directly influenced by environmental cues, especially light, which is why circadian rhythms are tied to the cycle of day and night. During the day, light exposure prompts alertness and keeps us awake and active. While at night, a lack of light signals to our bodies to produce melatonin, a hormone that prompts sleepiness. And so we have a sleep-wake cycle.What happens when our sleep-wake cycle goes wrong?
Our bodies don’t work efficiently and we can struggle to fall asleep, we wake during the night or wake very early in the morning. Overall we get a lower quality of sleep and feel tired during the day.What can we do to protect a healthy sleep pattern?
- Expose ourselves to natural light early in the day; take a walk outside.
- Get exercise.
- Follow a consistent sleep routine.
- Limit our exposure to blue light later in the day.
So how do I limit exposure to blue light at night?
You can limit the amount of blue light entering your eyes in a number of ways. One of the easiest ways to do this is by wearing blue light blocking glasses. These blue light blocking glasses filter out a large amount of the blue light emitted from screens before it hits your eye. By wearing these blue light filtering glasses later in the day you can limit some of the disruption caused by screens to your melatonin levels. This can reduce the effect the blue light has on the all important sleep-wake cycle. Limiting screen time in the 2-3 hours before bedtime is hugely important to reduce the amount of blue light you are exposed to. Social media and other interactive forms of media are especially disruptive to sleep. Limiting this screen time is easier said than done, so if it can’t be avoided, e.g. for work, blue light glasses can be beneficial here. As there has been a large increase in the number of people working and studying from home as well as binge watching tv, there has been a significant increase in screen time for many people. This is causing a greater exposure to blue light and its effects. New research seen in the Journal of Applied Psychology has shown that wearing blue light blocking glasses before bed can lead to better sleep and even better decision making and a better productivity at work. Blue light blocking glasses may also be of benefit to those who work night shifts as they are exposed to artificial light and may find it difficult to sleep when they get home.

All of our glasses are available with blue light lenses. You can get these as prescription glasses, non-prescription glasses or as reading glasses. Some people also refer to blue light blocking glasses as ‘computer glasses’ or ‘gaming glasses’. For a guide on how to purchase glasses online read our article here.
Our blue light lenses are some of the best available to purchase in terms of their ability to filter out blue light. The quality of these lenses can vary greatly and while some look like good value on paper, they may only be blocking out a smaller percentage of blue light rays from entering the eye in reality.
