The average Canadian spends about six hours per day using computers, tablets, and smartphones. Unfortunately, the blue light emitted by these devices can cause strain and fatigue in the eyes, leading to blurred vision, difficulty focusing, and even headaches. Blue-light glasses can reduce these symptoms and help you enjoy screens without discomfort.
What is Blue Light?
Blue light is part of the visible light spectrum, which means it can be seen by the human eye. It has a shorter wavelength and higher energy than other colours in the spectrum, ranging from about 380 to 500 nanometers.
While blue light is naturally emitted by the sun, it’s also produced by artificial light sources, such as LED lights, fluorescent lights, and digital screens, like those on smartphones, tablets, televisions, and computers. It plays an essential role in regulating our natural sleep and wake cycles, which is one reason excessive exposure can be harmful. Additionally, frequent, prolonged exposure to blue light can also be detrimental to eye health.
The Benefit of Blue Light Glasses
If you’re spending significant amounts of time in front of a computer screen or other blue light sources, blue light glasses can help reduce the negative effects associated with exposure. These specialized glasses are designed with lenses that filter out a portion of blue light to reduce the amount that reaches the eyes, helping to lessen eye strain and discomfort associated with long hours of screen use, known commonly as digital eye strain or computer vision syndrome.
Wearing blue light glasses offers an array of benefits, including:
- Reduced eye strain
- Reduced risk of eye disease
- Improved sleep
- Reduced dry eye
Furthermore, wearing blue light glasses can help you work longer and increase your productivity while working on screens.
