Does a privacy screen protector harm the eyes?
Recently, I applied a privacy screen protector, but I've been feeling that my eyes get sore and tired more easily when looking at the screen, and my vision becomes blurry. Is the privacy screen protector harmful to my eyes? Could it worsen my myopia?

Under normal circumstances, privacy screens do not harm the eyes, but prolonged use may cause eye discomfort.
Privacy screens typically achieve their function by reducing screen brightness and contrast. However, the privacy screen itself does not directly harm the eyes. Its main function is to limit the viewing angle of the screen, reducing the possibility of bystanders seeing the screen content from the side, and preventing bright light and dust from irritating the eyes.
Due to the reduction in screen brightness and contrast caused by the privacy screen, prolonged use may cause the eyes to work harder to focus, adapting to the darker or lower-contrast display, which could lead to symptoms such as visual fatigue, dry eyes, or discomfort, particularly noticeable when used in poorly lit environments. It is recommended to maintain appropriate screen brightness and contrast settings in daily use, ensuring the screen is clearly visible without being overly glaring.
In daily life, it is also important to use your eyes reasonably, avoid staring at screens for extended periods, take timely breaks, maintain an appropriate viewing distance, and perform eye exercises to relax the eyes and maintain ocular health.
