Your phone habits could be detrimental to your health, and one woman found that the hard way. According to news reports, a 25-year-old woman from Taiwan discovered she has over 500 holes on her cornea using her phone on maximum brightness for two years.
She consulted a doctor after due to pain and bloodshot eyes. Her doctor, Dr Hong, found over 500 holes on the cornea, and attributed her condition to exposure to more than 600 lumens every day over a period of two years—twice the amount that our eyes can take.
The woman, who goes by the name Chen, said she would increase the brightness of her phone screen in order to be able to see it outside (screen visibility is low when you use the phone in direct sunlight). Over time, she got used to using her phone on maximum brightness.
Dr. Justin Bazan, a medical advisor for The Vision Council, said: “With an increase of digital technology, many individuals suffer from physical discomfort after screen use for longer than two hours at a time.”
Of course, it’s not limited to increasing the screen’s brightness in broad daylight. Doctors have found that your phone in darkness can also damage your eyes, while blue light emitted from your phone can also lead to retinal damage.
If you’re using iPhone, turn on Night Shift mode to reduce blue light emission.
