If you work on a computer, use a smartphone, watch TV, or simply go out in the sun, you are being exposed to high-energy visible (HEV) blue light. Too much blue light exposure can damage the eyes over time and even lead to vision loss. Today, more people are wearing blue-light-blocking lenses to protect their eyes from these potentially damaging rays.

The most common effects of too much blue light exposure are eye strain, blurred vision, and headaches. However, recent studies have focused on blue light’s negative impact on the circadian rhythm and found that watching TV or using a tablet before bedtime, for example, can result in restlessness and disrupted sleep cycles. In extreme cases, too much blue light exposure can even lead to permanent eye damage and vision loss.
