Blue light blocking glasses have surged in popularity as screen time increases. But what does the science actually say about their effectiveness?
What Is Blue Light?
Blue light is a high-energy visible light wavelength between 400 and 500 nanometers. It is emitted by the sun, LED lights, and digital screens. While natural blue light helps regulate our sleep-wake cycle, excessive screen-emitted blue light can cause issues.
The Evidence on Eye Strain
Research suggests that blue light from screens is not intense enough to cause direct damage to the retina. However, many users report reduced eye strain and fewer headaches when wearing blue light glasses during extended screen sessions.
Sleep and Blue Light
The strongest evidence supports blue light glasses for sleep improvement. Studies show that blocking blue light in the evening helps maintain natural melatonin production, leading to better sleep quality.
Should You Try Them?
If you spend more than two hours daily looking at screens, blue light glasses are worth trying. At Urbanvendure, our blue light glasses block between 60% and 95% of high-energy blue light, depending on the model.
