However, excessive exposure to blue light, especially in the evening, can disrupt the delicate balance of your body’s innate sleep-wake cycle, affectionately known as your circadian rhythm. You may have heard that blue light emitted by electronics is bad for your eyes, but this claim lacks concrete scientific evidence. We need blue light from the sun as it provides many positive effects, including heightened attention, improved reaction times, and an uplifted mood. Understanding Blue Light & Its Effects on Visionīlue light is part of the visible light spectrum and is emitted by the sun and digital devices like laptops, smartphones, and LED lights. With these abilities, blue light lenses are excellent for those who spend a lot of time in front of screens, promoting better overall health and comfort for the eyes. This can have several benefits, including hormone regulation and increased alertness and may help manage depression and anxiety. While there are not enough studies to definitively prove the effectiveness of blue light lenses in reducing digital eye strain, preventing dry eyes, or protecting against macular degeneration, they can still help regulate sleep-wake cycles and circadian rhythms. These lenses filter out harmful blue light from digital devices like computers, tablets, and smartphones. Blue light lenses are gaining popularity as people become more aware of the potential damage caused by blue light to our eyes.
