There are some cost you cannot avoid, going to optometrist is one of those. I wanted to get a pair of new glasses. Not because I can’t see clearly with my old glasses, but rather want to get a new look. I thought my original sight prescription is still OK, so I didn’t bother to visit an optometrist before buying glasses. When I pick my glasses, I let the shop did sight test for my new glasses. When I pick up the new glasses, I find my vision of my left eye is kinda funny, like looking through magnify glasses. I have the shop change the lens but the sight is equally bad. The sales said I have a lazy eye, but that doesn’t sound right to me, I am fine with my old glasses. So I figure it is time to seek professional help from an optometrist and do a full eye exam. It turn out the result of the sight test is away off. My eyes are quite health, but the left lens is +1.0 more than it should be. That’s why I am seeing funny vision and thought something is wrong with my left eye. The moral of this story: 1. Never trust any sales person. 2. You can’t cheap out all the time. If the money is ought to spend, then you have to spend the money.
