Have you ever used the “dark mode” function on your phone? This setting essentially reduces the amount of light, and particularly blue light, that your phone screen emits. It can be difficult for some people to adjust to dark mode, because they are so accustomed to the standard light setting. But using dark mode has some serious benefits for your vision, your overall health and your phone’s battery, so it is worth giving it a try.
Here is an overview from optometrists in Cape Cod of why you ought to consider switching your phone to dark mode, especially in the evening.
Reduce eye strain
Blue light comes out of your TV, your computer, your phone, your tablet—essentially, if it has a screen, then chances are it emits blue light. But during dark mode, that blue light is reduced, as is the general amount of light that your phone screen emits. Blue light contains more energy than the yellow light your phone emits during dark mode. This means there will be less of a strain on your vision.
Staring at a blue light screen for too long, for too many days on end, can cause serious and permanent eye problems. These include macular degeneration, which can leave you without eyesight. Using dark mode even just during the evening can help prevent that from happening to you.
When you stare at a brightly lit-up phone screen right before your bedtime, you make it difficult for your brain to wind down and prepare for a good night’s rest. This is why many people choose to set their phones to dark mode (also sometimes called “sleep mode” or night mode”) at a certain time each night, so that their eyes and minds won’t become too overstimulated to sleep.
A good night’s sleep is invaluable. It will make the next day of your life much more pleasant, and it allows you to live a more enjoyable and enriching life. Getting a healthy amount of sleep is also good for your general health, including your metabolism, your heart rate and your vision!
Improve battery life
This benefit doesn’t have much to do with eyesight, but it is still worth noting! When you switch your phone to dark mode, your phone uses less energy, as it is emitting less light. That means you conserve battery power. If you know you’re going to be away from home longer than usual and might not have a chance to recharge your phone during the day, setting it to dark mode is a great way to ensure the battery does not die.
