Pavel Jelic Nowadays, many things are easily solved online. This means that many employees in different companies, most often separated from the business, sit at computers and deal with e-mails and other business matters. Computers are good servants but evil masters. They can speed up many things and activities, but unfortunately it takes its toll, namely eye pain or insomnia user. Monitors radiate blue light, which both of these problems (and several others) cause. In the end, the user comes home tired, he wants to rest, but unfortunately he doesn't quite succeed.

I am one of those users who spend several hours a day at the computer. All my work is done on the computer only, which means that I drink my morning coffee at the computer, as well as my evening tea. Unfortunately, I'm not quite the youngest either, and lately I've started feeling pretty tired. It wasn't so much physical fatigue as it was eye strain, headache, trouble falling asleep, and poor sleep. It kind of dawned on me that my body was telling me that something was wrong. Every day I woke up with completely dry eyes, when every blink was a pain, with a headache and a feeling of insomnia. But I didn't want to admit that blue light could be the problem, even though I've already written several different articles about it. However, I had no choice but to try to limit blue light, especially in the evening and at night.
Within macOS you will find Night Shift, which is a simple application that allows you to set a blue light filter at a certain time of day. However, it should be noted that in the Night Shift settings you will only find the setting of the (de)activation time and the level of filter strength. So once Night Shift is activated, it has the same intensity throughout its entire duration. This can of course help a little, but it is nothing special - especially if you set the level of warmer colors close to the default value. Even before the addition of the Night Shift function, a lot was heard about an application called F.lux, which was both very popular at the time and was the only option with which you could apply a blue light filter. But when Apple added to macOS Night Shift, that's how many users gave up on F.lux - which at first glance seems logical, but at second glance it was a big mistake.
F.lux can do this with your screen. Macat or MacBooku work during the day. By this I mean that it does not work like Night Shift, where you only set the time to activate the blue light filter. Within the F.lux application, you can set options that will make the blue light filter constantly stronger depending on what time it is. This means that the filter can be activated, for example, at 17 p.m. and will gradually become stronger until nightfall, until you turn off the computer. F.lux works immediately after installation and does not even need to be set in any complicated way - you just choose the time you get up in the morning. Any weakening of the filter is set accordingly. The F.lux application works only based on your location, which it uses to calculate how strong the filter should be set. However, there are also various profiles available, for example for working late into the night, etc.

LSA Magazine F.lux available absolutely free of charge and I can personally say that it was easy to pay for it as part of a subscription. After I installed F.lu.x, I found out on the first night that this is just the thing. Of course, I didn't want to judge the app's functionality after the first night, so I continued using F.lux for a few more days. Currently, I have been using F.lux for almost a month and I must say that my health problems have practically completely disappeared. I have absolutely no problem with my eyes now - I don't need to use special drops anymore, I last had a headache about a month ago and as for sleep, I am able to lie down after work and sleep like a baby within a few minutes. So, if you also have similar problems and work several hours a day on the computer, it is quite likely that the blue light from the monitors is responsible for them. So definitely give F.lux at least a chance as it can solve all your problems. F.lux is free, but if it helps you as much as it helped me, don't be afraid to send at least some money to the developers.
