I bought plastic lense in Chin

My eyes are 250, 225 degree. It cost me 1100RMB,650 for frame, 450 for lense. It is 60% thinner, which is only 2mm. I bought them in a top eye glass store in Shanghai. But I almost forgot the name. It is a very big "LIAN SUO" store.
My hu*****and's eye lense is about 2000RMB because his eyes are 750, 800 degree and his glass is 70% thinner.
What we bought are both plastic and imported from Japan or Korea.
