Went back from the library I found my sight has falling down!I can hardly recognise my classmates!How terrible! My eyesight didn't drop even during the time of college entrance examination!How can it happen?I can still remember clearly that all of my classmates were so envious of my excellent eyesight.At that time my sight is 2.0 and I can see clearly what wrote on the blackboard no matter how small they were.Am I getting old?Oh My God!I think I have to look far into the distance frequently and eat something good to eyes during meals~
