Effects of Blue Light on Your Eyes

In addition to affecting your natural sleep and wake cycles, blue light can negatively affect your eyesight. Because blue light is among the shortest of light waves, the light waves flicker more easily compared to longer, weaker light waves. This flickering creates a glare that can reduce visual contrast, and affect the sharpness and clarity of your eyesight.

Additionally, it can cause eye strain, blurred vision and headaches. In extreme cases, too much blue light can even lead to permanent eye damage and vision loss.
