Sight Problem

Hubby is getting so worried of me because i am having problem with my sight. Hubby told me that i need to see a doctor very badly because i cannot even see words that are written in the television within just a few steps away from our couch, but i told him that i don't need a doctor, i just have to get this Zenni Optical: Sell Rx Glasses $8 with case! for reading and that's all i need. Because my problem is only for reading and i am sure that this is just a solution to my problem.
