The PWM of the iPhone X screens would be causing headaches and eye fatigue in some users

The use of the iPhone X would be generating different problems to the health of a small group of users as they have been reporting in a thread of the Reddit forum because of a software problem. Among these health problems we find headaches and eyestrain after seeing the screen of this device.

A new problem on the iPhone X screen

These problems lie in the PWM which is the modulation of the pulse width of the screens , which is different in the different devices that in addition to the screens of the mobiles is also present in monitors or televisions.

The image that we are seeing in our device is constantly refreshing but we do not appreciate the blinking since the interval is adjusted to avoid this phenomenon. This may be something beneficial for us is causing health problems for some users. To give you an idea, in the following videos we can appreciate the refreshment of the screen on the iPhone 8 and iPhone X.

The first corresponds to the iPhone X where if you can see the refreshment of the screen, and in the iPhone 8 that we see in the second video, there is no type of refreshment on the screen.

That the refreshment of the image in the flagship of Apple is appreciable in the most sensitive users can have consequences like those that have been described in the forum of Reddit: headaches and eye fatigue. Users are already asking Apple to give the option to deactivate the PWM  in the accessibility options so that these people can use the device as normal.
