The iPhone Accessibility section contains a number of additional features for users, especially those who need special assistance to use the device in their daily lives. One of these is the ability to turn off the color filter, which turns the phone screen into a black and white display (grayscale) for people with color blindness. This change makes it easier for them to read text, with less distraction from color issues.
Monochrome screen helps reduce eye strain and fatigue when used for long periods of time and increases concentration
However, there are no restrictions on the use of iPhone Accessibility, so people who are not color blind can still use Grayscale for the little-known benefits it brings. Black and white mode makes the device more boring and monotonous by "washing away" all the brightest, most eye-catching things, but it is effective in preventing distraction when looking at the screen.
Accordingly, monochrome screens are effective in reducing distractions, avoiding distractions caused by colors. Programmers always design the notification section as a bright red dot in the corner of the application to attract users' eyes, urging them to click to see new content, because they understand that colors play an important role in attracting attention. This will no longer affect when the screen is only black and white, even users intentionally looking for a reason to look at the phone becomes more difficult.
That boredom and monotony actively contribute to the process of reducing the attractiveness of phones and social networks to users, helping them spend less time looking at these devices, and at the same time focus on other work or what is really important when they need to connect and contact.
Toggle color filter mode to change the display on iPhone
Black and white screens also have health benefits by reducing eye strain and fatigue during long periods of continuous use. The greyscale of the screen reduces contrast and visual stimulation to the eyes - effects that can lead to headaches if the user stares at the screen for too long.
To activate the black and white screen mode on iPhone, users go to settings in the following order: Settings -> Accessibility -> Display & Text Size -> Color Filters -> drag the switch to On (gray). At this point, the phone will no longer display color. At the bottom of the interface, there will be a slider to adjust the Intensity of the gray color, with the principle of dragging all the way to the right is the maximum, to the left will reduce the brightness and add other colors.
If you want the device to return to its original display, simply drag the Color Filter switch to Off (Gray).
Accessibility is also available on smartphones using Google's Android operating system, also serving the purpose of supporting people with disabilities or difficulties in behavior and communication. However, the settings and customizations may be different from iPhone and not the same between devices from different manufacturers.
