When you stare at a screen for hours at a time, whether it is a TV, computer, phone, tablet, you are exposed to blue light from the device. Studies suggest that, over time, exposure to the blue end of the light spectrum could cause serious long-term damage to your eyes. We spend so much time in staring our digital screen. These electronics are emitting a dangerous blue light, which is negatively impacting not only our vision but also our overall health. But we have to admit the fact that we love this technology.
It is important to protect our own eyes. The best way to protect your eyes against eyestrain from blue light in devices is to take regular breaks using the “20-20-20” rule: Every 20 minutes, shift your eyes to look at an object at least 20 feet away for at least 20 seconds.
