​Using Night Mode To Reduce Blue Light

When we use our phone a rather digital devices like computer for a long time right before bed, we get trouble in sleeping. The reason is none other than blue light emitted from the devices. As we all know, the sun is the major source of blue light. Blue light stimulates and wakes us up. But too much of exposure to blue light may disturb our sleep cycle. Researchers have found out that blue light affect our body's circadian rhythm. It is nothing but our natural sleep and wake cycle. One should limit screen time to 1 or 2 hours before going to bed and using night mode can minimize blue light exposure.

Night mode, also called as eyecare mode, is a setting offered by most of the digital devices that we use today. It reduces screen brightness to a certain extent and as a result eye strain gets reduced. The background of the screen turns to black from bright white. The text becomes coloured so as to ease our viewing experience. This specific setting reduces glare and eye strain, providing us a comfortable reading experience.

Our body does not get confused by the warm colors offered by the night mode and makes a person easier to sleep. If use normal mode on a dark room we may get digital eye strain and night mode is helpful for reducing the contrast on the screen, providing viewing pleasure to our eyes.

It is found out that our eyes do not get damaged from blue light. But limiting it can help a person feel comfortable and sleep easily. On the other hand adequate amount of blue light is necessary for decreasing nearsightedness in small children. Thus it is better to use night mode during night time.
