Hi Alan,
I’ve been wearing glasses for 10 years, which means I’ve done lots of eye exams in Chengdu. lol
I used to take eye exams in West China Hospital. But they still do it with the old way. Like putting examining lenses one by one using hands not the virtual lenses controlled by computers. So it’s not that precise. And I went to Jingyi Glasses(Chunxi Rd North 19-21 春熙路北段19-21) They get several options of eye exam, like normal ones and professional ones. I recommend to get a professional optometrist. The price is lower than 10 yuan, after all.
And if ur spectacles are ok (like the degree of astigmatism is under 400) then u could get lenses there. However, if they don’t get proper lenses for u and tell you they have to book the lenses. My advice would be get the lenses on Renmin North Road 2nd Section(near the train station) . There are lots of optical shops offering lenses with reasonable price.
