Blue Light Glasses vs. Night Mode: Which Is More Effective for Sleep?


We are constantly exposed to screens emitting blue light from our smartphones, tablets, and computers. This prolonged exposure to blue light, especially during the evening hours, can negatively impact our sleep patterns and overall well-being. To combat this issue, many people turn to solutions like blue light glasses and smartphone/computer "night mode" settings. But which one is more effective for improving sleep? In this blog, we will compare the effectiveness of blue light glasses and night mode settings, and provide recommendations on when to use each.

Understanding Blue Light

Before we dive into the comparison, it's essential to understand why blue light affects our sleep. Blue light is a high-energy, short-wavelength light that is abundant in natural sunlight and emitted by electronic devices. It plays a crucial role in regulating our circadian rhythm, the body's internal clock that controls our sleep-wake cycle. Exposure to blue light, especially in the evening, can suppress the production of melatonin, a hormone responsible for promoting sleep.

Blue Light Glasses

Blue light glasses are specially designed eyewear with lenses that block or filter out a significant portion of blue light. They are a proactive approach to reducing the negative impact of blue light on our sleep patterns.

Effectiveness of Blue Light Glasses

Blue light glasses can effectively reduce the amount of blue light that reaches your eyes, mitigating the disruption of your circadian rhythm.
Many users report improved sleep quality and falling asleep faster when using blue light glasses in the evening.
They are particularly useful for individuals who spend extended hours in front of screens or those who have difficulty falling asleep at night.


Wear blue light glasses in the evening, ideally two to three hours before bedtime.
Use them consistently if you have a habit of using electronic devices at night.
Baxter Blue's range of sleep blue light glasses are a great choice for those who want a non-intrusive solution that doesn't require changing screen settings.

Night Mode on mobile phones

Night mode, also known as "blue light filter" or "night shift" on different devices, is a software feature that reduces the amount of blue light emitted by screens. It typically shifts the screen's color temperature towards warmer, reddish hues during the evening and nighttime hours.


Night mode can be effective in reducing blue light exposure, especially when enabled during the evening and nighttime hours.
It is a convenient solution as it doesn't require additional accessories like glasses.
Night mode settings are available on various devices, including smartphones, tablets, and computers.


Activate night mode on your devices in the evening, preferably a few hours before bedtime.
Consider using night mode in conjunction with blue light glasses for maximum protection.
Night mode is a suitable option for those who prefer a software-based approach and don't want to invest in glasses.

Both blue light glasses and night mode settings offer effective ways to reduce the disruption of sleep patterns caused by blue light exposure. Your choice depends on your preferences and habits. Blue light glasses provide a proactive, physical barrier against blue light, while night mode offers a convenient, software-based solution. For the best results, you can use both in combination, ensuring that your eyes are well-protected from the harmful effects of blue light. Ultimately, prioritising your sleep health is key, so experiment with these solutions and find the one that works best for you.
