![]() Anti-reflective coatingīlue light lenses use anti-reflective coatings (otherwise known as anti-glare) which minimise the amount of light reflected away from the eye. These wavelengths are those found to be most harmful to the eyes, usually anywhere between 380 to 450 nm (nanometers). What these micro-layers do is alter the way light is transmitted or reflected, and so blue light lenses are engineered to either absorb or reflect a precise group of wavelengths. Blue light lenses and the ways they protect us Micro-layer technologyīlue light lenses are made with minuscule ‘micro-layers’ built into the lenses. Just like the lenses protecting us from the harms of UV light, blue light lenses act as a protective barrier between our tender eyes and the risks of advanced technology and the smartphone age. It’s too penetrating, and our eyes cannot protect us against its high energy levels. ![]() Most importantly: our eyes cannot block out blue light. So: blue light has a lot to answer for! It disrupts our natural sleep patterns, causes eye strain, and a whole host of other eye complaints. It can attack our eyes, causing tiny ruptures and microtears in our retina which we definitely do not want. Because blue light has more energy, it causes more problems for our eyes. ![]() Blue light has more energy and as such is categorised into the HEV category (HEV stands for high-energy visible, if you were wondering). That’s right, and it’s essentially nature’s solution to keeping us awake and alert. Science doesn’t have to make sense, right?! So, blue light rays have more energy? On the blue end, the rays are shorter but have more energy. On the red end of the colour spectrum, the rays are longer but have less energy. Now, each subtle variation of colour has an individual energy level and wavelength. Of the elementary colours emitted by the sun (yellow, green, red, orange, and blue) there are thousands of subtle variations, like light yellow, dark yellow, dark green and so on. Įssentially, blue light is just another kind of light ray emitted by the sun and is part of a ‘spectrum’ consisting of varying energy levels. We’ve covered this in detail elsewhere, so be sure to take a look. The solution is blue light lenses, but how do they actually work? Sit tight and we’ll tell you. In this article, we’re going to investigate the science behind blue light and what we can do to protect our eyesight. Before long, they’re having headaches, eye pains, and find themselves squinting a lot. Here’s an example: a group of people spend their lives reading physical newspapers, and then all of a sudden the newspapers are replaced by a smartphone emitting a bright light that, according to research, causes all manner of eye complaints. In as little as a decade or two, the use of digital devices has accelerated so quickly that our eyesight has not yet caught up and is paying the price. ![]() Computer glasses are also known as computer gaming glasses, yellow tinted glasses for computer, blue blocker glasses for computer or glasses for computer screen protection.įirmoo offers prescription computer glasses, non-prescription computer glasses, reading computer glasses for men and women.Technology is now so pervasive and wide-ranging that our eyes have not been able to adapt. Here are the two main features you'll see in glasses like these:įirmoo computer glasses protect your eyes from computer screen. They're designed to: reduce glare (a major cause of eyestrain), increase contrast, and maximize what you see through the lenses-making it easier to look at a screen for longer periods of time. This is because the visual demands of computer work are unlike those associated with most other activities.Ĭomputer glasses are special-purpose eyeglasses meant to optimize your eyesight when you're looking at digital screens. When you work at a computer for any length of time, it's common to experience eye strain, blurred vision, red eyes and other symptoms of computer vision syndrome (CVS).
