My friend has done this before, about two years ago. But the exact price I don't remember. You can come to the eyemasters' web store to have a check which is so easy to be done. At the same time, you can also consult the detailed things besides the price. Hope this information is helpful for you. Wish you good luck.
It depends on what kind of exam you want to have, eye exam for glasses or contacts.
And also it depends on the location of the stores.
It may be around $40~ $100 for eye exam. And the exam for contacts will be a little cheaper than for glasses.
Here is the address of the eyemasters website: http://www.eyemasters.com/eye-exams/
You can get more information from it. Hope you like it.
