Is there a place in Walmart where I could have my eyesight checked and possibly purchase eye glasses at a reasonable price?

Yes ma'am

Yes, as Jim said Super Center.

Yes

Yes, there is as long as you go to a supercenter and not a smaller marketplace

Yuppers

Yes, there is. As, Bill said they do take most insurance. I have eyes examined there before and bought glasses there too. Good priced. But I did find that if you have a Costco membership they were even better priced and you got more features like transitional lenses scratch proofing and some other things for a great price. Costco does take insurane but not all.

Yes there is. They take most insurance
