This is an awful habit, when you think about it! You may be able to prevent AMD (age-related macular degeneration) Because the sun is a natural source of blue light, when you use your phone at bedtime you are essentially telling your brain that it’s time to wake up. Your sleep should improve, tooīecause blue light (especially the light from your smartphone at bedtime) can impede your sleep pattern, using blue light lenses will encourage your brain to resume normal and healthy sleep patterns. Your eyes will feel more awake using blue light lenses, and your overall eye health will be greatly strengthened. Prolonged exposure to blue light creates digital eye strain and will gradually wear away at your eyes. You will reduce eye discomfort and strain Now that our science lesson is over, we’ll quickly run through some of the benefits of blue light lenses. We recommend that you opt for the lightest pair of lenses with the highest optical clarity.
Aside from the usual things like comfort and style, the material of your lenses can affect how much blue light is blocked. It’s important to consider what blue light lenses are made from, too. This then enables more light to transmit through the lens, combatting glare in much the same way that polarised sunglasses do. 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. Technology is now so pervasive and wide-ranging that our eyes have not been able to adapt.
