Blue light has been a buzzword in relation to our habits within the digital age. In today’s increasingly digital world, we spend a majority of our day looking at a screen, whether it’s a phone, TV or computer.
What is Blue Light?
Light is made up of various colours with each one carrying a different energy and wavelength. Red rays have longer wavelengths and less energy. The other end of the spectrum, blue rays have shorter wavelengths and more energy, which strains the eyes over increased exposure. Artificial blue light is known to be emitted through digital screens.
The Effects of Hours of Screen Time
The human body wasn’t created to support such exposure to blue light. Natural blue light from the sun isn’t all bad as it can actually be beneficial during daylight hours because they boost alertness, elevates mood, and increases cognitive function. However, exposing ourselves to artificial blue light for longer periods of time can cause “visual nose” that reduces contrast and can contribute to digital eye strain. Exposure to too much artificial blue light, especially at night, from electronic devices may lead to poor sleep quality because it has shown to supress melatonin production.
What Are the Benefits of a Blue light filter on your glasses?
Blue light glasses filter or blocks the strongest rays of the blue light spectrum. This will help prevent digital eye strain and play a role in minimizing effects on your sleeping pattern. They’re also created with an anti-glare coating to minimize reflections on your lens and diminish halo’s seen during night time driving. People can’t even tell you’re wearing them — they look like any other pair of glasses and you can even incorporate them into your frame.
