Want to protect your eyes with blue light glasses?
Blue light glasses have become increasingly popular in recent years as many use them to reduce the negative effects of blue light exposure. Blue light is a type of light emitted by electronic devices such as smartphones, laptops and tablets. It is also present in natural light during the day.
The human eye is sensitive to blue light, and prolonged exposure can cause several harmful effects. These include eye strain, headaches and sleep problems. Blue light glasses are designed to block some of the blue light that enters the eyes, reducing these symptoms.
But do blue light glasses really work?
First of all, it should be noted that not all blue light glasses are created equal. Some glasses may have lenses coated with a filter that blocks blue light, while others only have a yellow tint. The effectiveness of glasses against blue light depends on the quality of the lenses and the amount of blue light blocked. We already wrote about how blue light glasses work in one of our previous blogs.
Research on the effectiveness of anti-blue light glasses is limited, but some studies have shown that the glasses can help reduce symptoms of eye strain and improve sleep quality. In a study conducted by the University of Houston School of Optometry, participants who wore blue light-blocking glasses two hours before bed reported a significant improvement in sleep quality.
Another study conducted by the University of Toronto found that participants who wore blue-light-blocking glasses three hours before bed significantly reduced melatonin inhibition, a measure of disruptions to the body's natural sleep-wake cycle.
On the other hand, some experts argue that blue light blocking glasses may not be effective in reducing eye strain and improving sleep quality. The American Academy of Ophthalmology states that no evidence supports the use of blue light glasses to reduce symptoms of digital eye strain. Additionally, the American Academy of Sleep Medicine states that there is currently no evidence to support the use of blue light glasses to improve sleep quality.
It is also important to note that blue light from electronic devices is not the only thing that can disturb our sleep and cause eye fatigue. Other factors such as the overall brightness of the screen, distance from the screen and duration of use may also affect this.
How effective are glasses in reducing the effects of blue light on the eyes?
Glasses are the obvious choice to reduce the effects of blue light on the eyes. They are light and comfortable, so they are easy to wear at night. In addition, they are made of plastic or other materials that prevent blue light from entering your eyes, which means that they will help you fall asleep faster and improve the quality of your sleep.
Sounds great! But what about the fact that some experts aren't convinced that anti-blue light glasses are as effective as they claim?
Some research suggests that the screen isn't the only factor that affects whether or not anti-blue light glasses help with sleep problems. Other studies have shown that leaving a device on for long periods of time (eg overnight) can disrupt your circadian rhythm and cause disruptions in your sleep patterns. That's why we recommend that you avoid using devices like phones and tablets before bed, as they can make it harder to fall asleep and likely have a negative effect on your circadian cycle.

If you have symptoms of eye strain and trouble sleeping, it may be worth trying blue light blocking glasses. However, it is important to choose glasses with high-quality lenses and consider other factors contributing to your symptoms.
We can conclude that blue light glasses help reduce eye strain symptoms and improve sleep quality, but more research is needed to fully understand their effectiveness. It's also important to consider other factors that may be contributing to your symptoms, such as your occupation, lifestyle, and the amount of time you spend in front of a screen. If symptoms persist, it is always best to consult a medical professional.
