Harmful Blue Light
Harmful blue light is everywhere—both indoors and outdoors.
Outdoors is the biggest threat—with the sun serving as the largest source of harmful blue light. The intensity of harmful blue light outdoors is 100-500 times greater compared to exposure from digital devices.
Indoors, we're exposed to harmful blue light from our screens, LED displays, and digital devices. Because these devices are becoming more common, protection from this type of blue light is more important than ever.
Glare from digital and computer screens can cause your eyes to work harder—leading to digital eyestrain. According to The Vision Council, 8 in 10 American adults use digital devices for more than two hours per day, and 6 in 10 experience symptoms of digital eyestrain, such as:
- Dry eyes
- Blurred vision
- Neck and shoulder pain
