Do they have a vision center

Yes they do.

Most of the Super Wal-Mart's have one /

Yes may Walmarts vision forever spring forth and may everyone come to see Walmarts vision for a peaceful service circulation of all that it is and all it may become... May those who are blind come to see the world through the vision of Uncle Sam and Uncle xing

Yes they do have a vision center, not sure what it's called but they do have one

Ok
