A young woman from Taiwan who had been using her smartphone at maximum screen brightness for two years ended up with serious damage to her left eye, including around 500 small holes on her cornea.
The 25-year-old woman, surnamed Chen, works as a secretary, a job that requires her to frequently check her phone and respond to work-related messages as soon as possible. A few years ago, Chen discovered that by setting the screen brightness on her smartphone to maximum, she was able to easily read her messages even in bright sunlight. Her mistake was keeping that brightness level at all times, even when watching her favorite drama series on her phone for several hours at a time, with the light off. She got used to her ultra-bright screen, but her eyes did not, and in March of last year she started experiencing discomfort.
