Understanding Blue Light and It’s Effects Blue light is a high-energy visible light emitted by the sun and digital devices like smartphones, computers, and tablets. While natural blue light exposure during the day helps regulate our circadian rhythm, excessive exposure, especially at night, can wreak havoc on our sleep patterns and potentially cause long-term eye damage. With the average person spending over 7 hours a day looking at screens, our eyes are under more strain than ever before. This prolonged exposure often leads to symptoms like eye fatigue, headaches, blurred vision, and difficulty focusing – collectively known as digital eye strain or computer vision syndrome. And, blue light exposure in the evening interferes with our body’s production of melatonin, the hormone responsible for regulating our sleep-wake cycle. This interference can result in difficulty falling asleep, poor sleep quality, and daytime fatigue. The Science Behind Blue Light Blocking Glasses Blue light blocking glasses work by filtering out or blocking the blue light emitted from digital screens. The lenses typically have a slight yellow or amber tint, which helps absorb blue light. Some advanced lenses can block up to 99 percent of blue light while maintaining color accuracy. These glasses help reduce digital eye strain but can also improve sleep quality when worn in the evening. By blocking blue light, they allow your body to produce melatonin naturally, helping you fall asleep more easily and enjoy more restful sleep. Top Blue Light Blocking Glasses 1.
