Experts often recommend using the dark mode in electronic devices to protect the eyes from the blue light emitted from screens, but this procedure may not actually be as useful as it is promoted.
Dark mode allows the white or light-colored background on your electronic devices to change to darker, usually blacker. By switching to this mode, the background is dark and the text is light, unlike normally.
Is the dark mode better for your eyes?
To put your device in dark mode, go to settings where display and brightness settings are located. This is where you'll be able to switch to dark mode. Some apps also have their own dark mode, which can be found in the app's own settings.
Although you may feel that the dark situation may be a little better on your eyes, it is unlikely to prevent symptoms of eye strain such as headaches and dry eyes.
"The dark state will reduce the levels of blue light emitted from the electronic device screen, but perhaps not to the extent that it affects any harmful effect of blue light on the retinal spot," says Brian M. Debrov, director of the Department of Cataract Surgery and Ocular Lens Transplantation at Yale Medicine University Ophthalmology.
The spot is located at the center of the retina and is essential for a healthy eyesight. Age-related macular degeneration is one of the most common causes of vision loss.
Typical levels of blue light from consumer electronics are not significant in terms of the risk of retinal damage or macular degeneration, Says Debrov. In addition, there is no scientific evidence to prove that a dark mode can help reduce eye strain. Serious damage or complications to the eye do not pose a real risk when using the device.
Although dark mode may not help protect vision, it may help you sleep faster if you use electronic devices often before bedtime. Benefits of the Dark Situation
Using devices that emit blue light at night can increase your alertness, making it difficult for you to sleep. Since the dark situation is intended to reduce blue light, it can be particularly useful at night.
This is because blue light is thought to inhibit melatonin, a hormone that helps you sleep. A study in 2012, for example, found that blue light inhibits melatonin twice as much as green light. However, more research and studies are needed on a large scale to consolidate this claim.
"Whether blue light can affect melatonin production and the rhythms of the biological clock is a common claim, but it has not yet been scientifically proven," says Debrov.
Although there are not many other scientifically supported health benefits for the dark state, Frema:
- Helps you save battery life
- Reduce screen glare
- Makes it easy to adapt to the screen when you look at your device in a dark room
