The Myth of OLED induced Eye Damage
The claim that OLED screens cause eye damage is largely a misnomer or a result of misinformation.
OLED technology has been the subject of such unfounded accusations, but when analyzed objectively, the situation is different. One of the main reasons for the so called "damage" concerns is the blue light emission. While it's true that OLEDs, like many other display technologies including LCDs, emit blue light, modern OLEDs are designed with measures to mitigate potential harm. Manufacturers have incorporated features such as blue light filters. These filters can reduce the amount of blue light reaching the user's eyes, especially during low light conditions or when using the device for extended periods.
Another aspect is the perceived flicker in some OLED displays. Some people believe that this flicker can cause eye strain or other issues. However, the flicker in well designed OLEDs is usually at a frequency that is not detectable by the human eye under normal usage conditions. In fact, many OLED displays use Pulse Width Modulation (PWM) techniques to control brightness. When properly implemented, these techniques do not cause significant visual discomfort.
Moreover, the image quality aspects of OLEDs can actually be beneficial for eye health in some ways. The ability of OLEDs to produce deep blacks and high contrast ratios can reduce the overall visual stress on the eyes. When viewing content with clear differentiation between dark and light areas, the eyes don't have to work as hard to distinguish details. In comparison, in some LCDs with poor contrast, the eyes may experience more strain when trying to make out details in washed out or low contrast images. So, rather than being inherently harmful, OLEDs can provide a good visual experience when used with proper settings and features.
