In our modern digital world, screens are everywhere—from smartphones and tablets to laptops and LED lighting. While these technologies make life more connected and convenient, they also emit high-energy visible (HEV) light, commonly known as blue light. You may have heard concerns about blue light’s impact on sleep, vision, and long-term eye health, but how much of it is true—and how can you protect your eyes without ditching your devices?
Blue light isn’t inherently bad. In fact, it's part of the natural light spectrum and plays a role in regulating our sleep-wake cycles. But excessive exposure, particularly from digital screens and artificial lighting, may contribute to digital eye strain, sleep disturbances, and possibly even retinal damage over time. In this article, we’ll explore how blue light affects your eyes, what the latest science says, and how you can take simple, effective steps to protect your vision and preserve your eye health.
