Can I order prism in my progressive lenses?

[cheap glasses]

I am planning to order a pair of prescription eyeglasses online, I remember the exam which was taken few months ago, the eye doctor told me I have some vision problem with prism, but not serious, I only know that prism is added to an eyeglasses lens prescription only if a problem with eye teaming or eye alignment is detected, who can tell more information about it, such as how it can measured? And can I order it in my progressive lenses?
