The Science of Blue Light: Protecting Your Eyes in the Digital Age

With the rise of screens, blue light exposure has become a growing concern. Emitted by smartphones, computers, and LEDs, excessive blue light disrupts sleep cycles by suppressing melatonin production and may contribute to digital eye strain. Symptoms include dryness, headaches, and blurred vision. To mitigate risks, use blue-light-blocking glasses, enable "night mode" settings on devices, and maintain a 20-inch distance from screens. Studies show that wearing amber-tinted lenses before bedtime improves sleep quality by 58%.
