Of course, the best thing to do is to turn off your devices, or decrease your use with “Do Not Disturb” mode, at least an hour before bed. Both options reduce the brightness of your screen and minimize the amount of blue light you see, which helps with both your sleep and eye strain. Some apps, like Twitter, offer a night mode option, which allows you to make the same background/text changes.Īlso, some devices allow you to set a timer, so the color of your screen takes on a red hue. Reader View on iPhones, for example, allow you to declutter webpages and at the same time change the background to black and text to white, instead of black text on a white background. Night mode is the right modeįortunately, smart devices now offer several options for limiting your exposure. While blue light doesn’t cause any permanent damage, limiting your exposure at night will make it easier to fall asleep and your eyes will feel more comfortable. This is the same reaction our body has when it sees the sun.īlue light can also cause eye strain, especially in a dark room, which can leave your eyes feeling dry and tired. Blue light wakes us up and stimulates us by preventing the brain from producing melatonin. Smartphones, tablets, and other devices give off a lot of blue light. “At night, however, this is disruptive to sleep.” “Blue light is important during the day as it improves attention, reaction times, and mood,” CEENTA Ophthalmologist Sumit Gupta, MD, said.
But is it? If so, what does it do for you? You have night mode set on your phone, which you heard is better at night. You’re in bed, checking social media on your phone, when your screen gets darker and redder.
