Over time, our exposure to blue light can lead to cumulative damage. We spend hours on our phones, computers, and tablets, usually viewing them too closely. But we encounter many of them throughout our day and tend to engage them up close-especially with digital screens. Unsurprisingly, these sources are much weaker than the sun. Blue light is scattered by the atmosphere, which is why the sky looks blue.Īlthough the sun is our most significant source of blue light, many artificial sources exist, like digital screens, light bulbs, and LED lights. Our atmosphere protects us from the most harmful UV radiation by absorbing all UVC and some UVB rays. The sun is our primary source of blue light. Blue light is less powerful than UV radiation but can still be dangerous in high amounts.
Many people are familiar with UV light because of sun damage: it’s why we wear sunscreen and sunglasses. Blue light is part of the visible light spectrum (a small section of the electromagnetic spectrum) at the end, right next to ultraviolet (UV) light.
BLUE LIGHT FILTER GLASSES FULL
The world is full of light, some visible to our eyes and some invisible. But when and where you wear your eyewear can make a difference in the quality of your vision. You can wear your blue light glasses all the time, just like you can wear sunglasses all the time. Like sunglasses, blue light glasses can have long-term eye health benefits. Or, you can reap the same blue-light-blocking benefits with non-prescription lenses. Opticians can add a blue light filter to your prescription lenses to protect your eyes from blue light. Your lenses can be customized with treatments and tints to make your vision more comfortable and convenient. Today’s eyewear offers more than vision correction.
