What is blue light? According to Healthline, most electromagnetic waves are invisible except for a small band of waves, known as visible light, which can be detected by the human eye. Blue light is the part of the visible light spectrum that contains the highest energy and it has more potential to cause harm to the eye than other visible light.
Sunlight is the main source of blue light. When you're outside during the day, you expose to blue light (visible light) and ultraviolet rays (invisible light) but there are artificial sources of blue light as well — including computer and phone screens, and fluorescent and LED lights .
Research has shown that too much exposure to blue light can lead to digital eye strain (dry eyes, headache, blurred vision, etc.) It can also affect your sleep by suppressing the secretion of melatonin, a hormone that influences circadian rhythms. While all lights (even dim lights) can suppress the secretion of melatonin, blue light at night does so more powerfully and may potentially lead to the causation of other diseases like cancer, diabetes, heart disease, and obesity due to sleep problems (Harvard Health, 2020).
