我這1年來用smartphone 和電腦加上看電視，眼睛近視又加深了。
很是苦惱。看見下麵有帖子說打網球和看遠方對眼睛有幫助。
正好我的一個物理教授經常打網球，他學光學的。我剛才特地問了他一下。
他說play tennis helps eye a lot. He plays tennis 3 times a week. Sometimes he had business travel and didn't play tennis for 2 weeks. He could feel vey obvious that his eyes were worse. He said playing tennis was excising eye muscle.
I also asked about looking distance, he said looking distance is helping eye to relax.
He also mentioned that looking at moving stuffs like interstate car moving also excises eye muscle.
我準備看看有無可能從新打網球和看遠方來幫助眼睛。
