Reading/computer glasses

I went to my annual eye examination few weeks ago and guess what? my optometrist said i needed a pair of reading/computer glasses or a bi-focal. Yup, mom and dad, your son is getting old! 终于还是得了老花眼。。。。

I have been very busy since June. My doctor said my eyes overshot (basically crossed eyed) when my eyes are tired. A pair of reading glasses will help to relieve the stress on the eyes and prevent it from getting worst. So far, it works. Last Friday i was looking at some lab results (a bunch of graphs) for a project and i was having headache. Then i thought about the reading glasses. I put it on and went back to work and everything was fine. Some of my co-worker already warned me that our "parts" will start falling apart after 30. What to do? At the same time, i will remind myself to go workout regularly. Going to my yoga class every Thursday is not enough!
