Blue Light: What It Is and How It Affects Your Eyes

Blue light is a type of high-energy light that comes from digital screens, LED lighting, and sunlight. While natural blue light helps regulate our sleep-wake cycle, too much exposure from screens can be tough on our eyes, leading to discomfort, dryness, and blurry vision.

When blue light enters the eye, it reaches deep into the retina, which may increase the risk of long-term issues like macular degeneration. It can also interfere with sleep by lowering melatonin levels, making it harder to fall asleep if you've been on screens before bed.

To protect your eyes, consider using blue light-blocking glasses, adjusting screen brightness, and taking regular breaks. These small changes can help reduce eye strain and keep your eyes healthier, especially if you spend a lot of time in front of screens.
