People spend most of their time using digital devices. People who stare at their phones right before bed may experience trouble falling asleep. Blue light comes from the sun or from the screens we use which stimulates us and wakes us up. Exposing yourself to too much blue light at night can disrupt the sleep cycle. It is proven that blue light affects the circadian rhythm or the natural wake and sleep cycle of the body.
It is a good choice to limit your screen time before bed and use night mode. People sleep better and feel more comfortable when the blue light exposure is decreased and screen time is limited. Studies have shown that blue light affects sleep. It is recommended to give at least one to two hours before bed so the blue light won’t affect the ability to fall asleep.
Knowing More About Night Mode
A setting offered in many digital devices known to be night mode or dark mode decreases the screen brightness and reduces eye strain. The usual display is white background with black text. In the dark mode, the display becomes black background with white text and it shifts to lighter colors. The colors and contrast used in night mode help our eyes to adjust to the surrounding light.
Being exposed to bright lights at night makes us feel awake because the brain stops producing melatonin which is the sleep hormone. People use night mode so the display of warm colors will not confuse the body. It is easier to fall asleep in night mode than looking at a device with a regular display mode.
What Is the Benefit of Night Mode to My Eyes?
Using dark mode has a lot of benefits but it may also have its downfalls. Exposing your eyes to blue light has been linked to dry eyes, headaches, blurry vision, and digital eye strain. According to Raj K. Maturi, an ophthalmologist, some studies show a healthy dose of blue light can help in maintaining mental performance and decreasing nearsightedness in children.
The pupils dilate using a dark screen to take more information. Dilation is bad because the sharpness of vision is lessened. It can be a reason why it is difficult for some people to see every detail in dark mode. A special coating can be added to your new glasses which can help in blocking glare and blue light.
