Right after the initial vision correction, both eyes were 1.0 / 1.0. For a year, I used my phone and PC as much as I wanted, but just in case, there was a period of about 3 months when I only used my phone briefly for SNS and focused on studying with books. During that time, my vision even improved to 1.2 and 1.5, and after that it mostly stayed around 1.0 / 1.0.
Then 3 years ago, to try pursuing art, I studied drawing for about 2 years. I used a screen tablet, and during that time my vision dropped sharply to 1.0 / 0.6. The tablet is about as close to the eyes as a phone, and I heard that fluorescent light reflects off it, which is very bad for the eyes.
I stopped studying, and now it is staying at 1.0 / 0.6 ㅠㅠ Still, it does not interfere with daily life at all.
