9/20 New glasses

I have worn the glasses for 10 years.
When I was 10, I was told by the doctor that I was myopic.
Now, I am near-sighted of 850 degree.

Recently, my old glasses were broke. I bought a new one last
Sunday and it costs me about NT3700.
I bargained with the glasses shop owner over the price because
it’s a big money for me.
