Why may you need a pair of anti-blue light glasses?
Human eye is an amazing organ which reacts to light and gives us sense of sight. Eyes capture light and transform it into electrical impulses to our brain and let us interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment. Nowadays, we spend the most of our time staring at a digital screen, whether it's the computer at work, our personal cell phone, playing a video game, or just relaxing and watching TV. It is very common for us to spend more than 6 hours a day in front of a digital device. As we all know that white sun light can be separated by prism into "visible light spectrum". Blue light has the shortest wavelength of the visible spectrum, right next to UV light. Its short wavelength and high frequency make it highly penetrative, able to reach as far back as the retina in your eyes. This can cause digital eyestrain, headaches, dry eye, fatigue, and even insomnia.
Our Zacway 2140 Anti-Blue Light Glasses lower the amount of blue light entering your eyes and help reducing the causes of digital eyestrain. Apart from that, good habits may also help you keep your eyes away from digital eyestrain, like taking frequent breaks and looking away from the screen to a distant sight.
Choice between Pale Amber Lens and Amber Lens
Normal sun light is white and consists of the visible light spectrum. Any lens claiming a strong blue blocking function should filter out more than 50% blue light and consequently lead to strong color distortion (imagine, more of the blue light are filtered out, the rest will looks yellowish).
Our pale amber anti-blue light lens strike a balance between protection and color distortion. We also offer amber Anti-Blue light lens which cut at least 60% blue light for some models, but it makes what you look yellowish.
