That is why developers are constantly thinking about such characteristics of gadgets that will allow us to use them without harm to health.
PPI (pixels-per-inch) – the ratio between size and resolution, or the number of dots per inch. The higher this indicator, the closer the pixels are to each other, and the clearer the picture, which means your eyes won’t have to strain to see it. That is, based on this characteristic, a small screen with a high resolution is safer for your eyes than a large one with a low one. For example, if you take two devices with the same screen resolution of 720 x 1280, but with different diagonals – 4.3 and 4.7 inches respectively, the PPI of the first will be 342, and the second – 312. Thus, the first will be more comfortable for your eyes.
Brightness and backlight technology. Digital gadgets, including smartphones, place us in an artificial environment in which we are forced to read text and recognize images against a bright background. Therefore, we stop blinking again, our eyes become dry, tense, and feel like sand, and eventually dry eye syndrome begins. This means that we need to protect ourselves benin phone number list from backlighting. Thus, IPS matrices, which use enhanced backlighting, expose our eyes to bright light. Modern OLED displays are safer in this regard, since their backlighting is selective. The LEDs that form the basis of the screen light up depending on where and what needs to be displayed. And the light impact of these displays is lower, and the light is much softer and less harmful to the eyes.
People with sensitive eyes are advised to choose smartphones with support for DC Dimming technology, which is used in almost all flagships and protects vision from harmful effects.
