Most monitors or screens have the ability to adjust this temperature manually, but there also programs that can automatically change the screen temperature over the course of the day. A more reddish, warmer color is best for dark rooms - while cooler, more blueish, ones work better for well-lit rooms. Because this blue light is so similar to the ultraviolet radiation that comes off the sun, it can trick your brain in thinking its daylight even when it's night - upsetting your hormonal balance and disrupting your sleep patterns. Most screens are made with LED technology that creates a harsh blue glow that can damage your retina. This flips white to black, and black to white - creating a less harsh light that still has high contrast.īrightness isn't just the amount of lumens coming off your screen, but can also be the overall temperature. In low light environments, you can apply a color inversion to your monitor. You should have plenty of contrasting color as well - there's a reason why most websites have a white background with black text, as this is easiest to read. You want the overall brightness to be an approximation of your surrounding environment. On the other hand, if it is dull or gray, then your screen brightness is set too low. The general rule of thumb is that if your screen seems like a light source in your room, that means it is too bright. When it comes to the overall brightness you need to follow the Goldilocks principle - too bright is not only a problem but so is too dim. From here you need to make sure the text size is about three times your minimum reading size. Ideally, you want your screen just below eye level and approximately 20 to 30 inches away from your face. Eye fatigue from screens is commonplace, especially in the tech-heavy society we find ourselves in. What you may not know is that even if you find yourself in a position like this you don't need to suffer from the deleterious effects. Anyone who has had a late night studying or working knows this feeling. Hunched over and bleary-eyed, you find you are starting to develop a headache from the bright light coming off your monitor.
