as the spread of higher editucation.more and more sutudents come to high school .It means that they have spend at lesst 16 years in the classesroom. When Iwas a entrant come to my college .I find a grand phenomenon that almost 75% of schoolfollow have glasses .I am happy. Because i am also a nearsightedness.
When I come to my classroom. It's glad to find a half of my classmate with a glasses and all of them have't a glasses cases or a glasses cloth with them. When they feel blurred vision that may caused by dirty things on lens.they clean the lens by clothes not by glasses cloth. I want to say :It's a bad habit .bacause It's harm to the lens .The right way's we shoule go with a glasses cloth,.and clean our lens by it
Now I want to say about how to choose a health glasses cloth. First, when choose the materials of the glasses cloth pure cotton is the best choose.second, you have to choose a glasses with better hydroscopicity so that you can easy to make your lens dry. Third, lighter color is better than high color, for the reason of easy to find the dust on the glasses choth. Last but not the least, glasses cloth mast be soft to feel.If it's too hard it will do harm to the glasses choth.
For all above I have say.It can conclude to be as it's a good habit for earsightedness to choose a well glasses cloth with them.And clean your glasses by it instead of by your clothes. eyes are the windows of your heart.we should not neglect the details.Do every we can to protect your windows!
