A Chinese man who frequently used a massage gun on his face and eyes had to undergo surgery after suffering lens dislocation and developing cataracts at the age of 42.

Mr. Luo, a fitness enthusiast from Wuhan, in Central China, purchased a battery-powered massage gun at the recommendation of a fitness instructor who told him it would work wonders on his tired muscles. After hitting the gym every two days, Luo was looking for a way to relax, and the massage gun proved incredibly effective. So much so that at one point, the 42-year-old man decided to use it on his eyes as well. Due to his busy work schedule, Luo’s eyes always felt tired and dry, so he thought that the massage gun would have the same effect on his eyes as it did on his muscles. He was wrong!
