In brief: Glasses power
Yes, the eye care professionals have instruments as do the optical department optician that can measure the strength of the eyes when they were prescribed, providing they were for that patient and made correctly.
However the glasses strength are not the same as the contact lens prescription. Your eye care professional can sort this out for you.
