But as with everything that is new and unexplored yet, conspiracy theories start to lurk around every corner.<\/p>\n
However, we are here to help you learn the myths and the truths about blue light!<\/p>\n
Blue light is a range of the visible light spectrum with wavelengths 400-450 nm, which makes it a type of high-energy visible light.<\/p>\n Where does the problem come from then and what should you know about blue light?<\/p>\n We are diving right into it!<\/p>\n We have collected some of the most important facts about blue light<\/a> that you should be familiar with in order to deal with it in the right way.<\/p>\n The main source of blue light is actually\u2026 the sun itself!<\/p>\n Sunlight contains red, orange, yellow, green and blue rays and a lot of shades of these colors.<\/p>\n What is more interesting, blue light<\/a> is the reason why we see the sky blue.<\/p>\n Walking outside during the day, you are exposed to blue light.<\/p>\n In fact, a certain number of daylight hours can be absorbed by the human body.<\/p>\n It becomes a problem when we introduce blue light at night as well – this way we disrupt our biological clock which can lead to health problems (including poor sleep, poor eye health, etc.).<\/p>\n Our eyes can successfully block UV rays from reaching the retina.<\/p>\n It is proven that less than 1 percent of UV radiation from the sun reaches the retina, even if you have not put your sunglasses on.<\/p>\n <\/p>\n Nevertheless, it is advisable to always wear sunglasses with 100 percent UV protection since they are essential for eye health!<\/p>\n In contrary though, blue light can penetrate the inner structure of our eyes.<\/p>\n According to studies almost 100 percent of the blue light<\/a> that we are exposed to, reaches our retina.<\/p>\n You may be confused by this one but it is actually true that not all blue light is harmful.<\/p>\n Thanks to blue light, our bodies know when we should be awake (throughout the day) and when we should go to sleep (after the night falls).<\/p>\n Therefore we are messing up with our circadian rhythm if we are exposed to blue light<\/a> in the evening.<\/p>\n Try reading a paper book before bed instead of your e-reader and switch off your devices at least an hour before sleep.<\/p>\n Yet, some studies have shown that certain types of blue light can have a positive impact on our bodies.<\/p>\n High-energy visible light boosts vigilance, helps memory and cognitive function and improves mood.<\/p>\n A light therapy is used to treat seasonal affective disorder (SAD) which is a type of depression related to changes in seasons.<\/p>\n With the right amount of blue light, the symptoms of SAD can be alleviated.<\/p>\n <\/p>\n It\u2019s been made clear that not all blue light is bad for you but too much of it can really be.<\/p>\n Especially for your eyes.<\/p>\n They can not block the blue light<\/a>, therefore they become irritated when we expose them to it for a long period of time.<\/p>\n The symptoms may include red, dry or sore eyes, as well as headaches and blurred vision.<\/p>\n However, digital eye strain can be prevented with a number of precautions – you can check them out in one of our previous articles!<\/p>\n <\/p>\n Been there, done that.<\/p>\n In fact, the low brightness of the screen is not a safeguard!<\/p>\n It actually has a very small impact since apart from blue light<\/a> there are a lot of other things that are harmful to your eyes.<\/p>\n Such are flickering, small fonts and so on.<\/p>\n Macular degeneration<\/a> is the condition which causes deterioration of the macula<\/p>\n Macula – the small central area of the retina, controlling the visual acuity.<\/p>\n The ability to complete any visual task requiring us to see detail depends on the health of the macula – reading, recognizing faces, driving, watching TV, using the computer, etc.<\/p>\n <\/p>\n Unfortunately, macular degeneration<\/a> can lead to permanent sight loss.<\/p>\n Blue light<\/a> is related to macular degeneration because our eyes can not block the blue light and it penetrates all the way to the inner of the eye.<\/p>\n Consequently too much blue light can cause damage to the light-sensitive cells in the retina.<\/p>\n <\/p>\n However, more research is needed in order to define how much is too much and the potential long-term effects of constant digital eye strain.<\/p>\n If you are a bit concerned about your health after going through the myths and truths about blue light<\/a>, we are happy to inform you that you can successfully reduce your blue light exposure!<\/p>\n You can do that by using software like ours – Iris<\/a> will reduce the blue light emitted from your computer or laptop screen.<\/p>\n It has a few different modes and detects automatically whether it is day or night.<\/p>\n Thereupon Iris<\/a> will change the color temperature and the brightness of your screen.<\/p>\n This way you will be able to use your device for longer without having a tired eye afterward.<\/p>\n Yet, it is recommended to take a break from the screen every once in a while<\/p>\n The aim is to move around every hour for at least 5 minutes or simply follow the 20-20-20 rule:<\/p>\n Every 20 minutes look at an object 20 feet away from you for 20 seconds.<\/p>\n Blue light<\/a> is naturally emitted by the sun and is needed by our bodies in order to regulate our biological clocks.<\/p>\n Too much of it though may cause worse sleep quality, eye strain and other health problems.<\/p>\n However, blue light therapy is used to treat people suffering from seasonal affective disorder (SAD) – it improves their sleep patterns and elevates mood.<\/p>\n In our everyday lives, we can deal with excessive blue light exposure by downloading<\/a> software like Iris<\/a>.<\/p>\n It reduces the blue light<\/a> emitted from the screen or by minimizing the time spent in front of a device in the evenings.<\/p>\n TEST
