上次做眼科检查是几年前，感觉视力越来越差了该怎么办
 
来听今天的讲解:
 
A: It's been a couple of years since my last eye exam and I think my eyes are getting worse.
 
现在距离我上次做眼科检查已经有好几年了，我觉得我的是越来越差。
 
B: We'll soon find out. Please look at the chart on the far wall and read the first line.
 
我们很快就能知道了，看那边墙上的表格，读出第一行。
 
A: E. O. R. S.
 
E.O.R.S
 
B: Okay, very good. Now try the line below that one.
 
好的，很好，现在试试看它下面的那一行。
 
A: That's a little blurry. I think I can make out a B, a T and that's it.
 
有点模糊，我想我能看清一个B一个T，还有就那么多了。
 
B: You're getting on in years. It may be time to change your prescription.
 
你这几年的度数又增加了。或许得给你换一换处方了。
