It happened when I try to read a book last night. I took out my eye glasses from the chest pocket, then unexpectedly, one of the lenses came out from the frame. and dropped on the floor. I found that the frame was broken. I couldn’t read or paint without the eye glasses. After I thought about it moment, then I decided to fix it. I used a scotch tape to held the frame and lens together. It was working that night but I went to an optician next day and got new frame.
