Go to the dollar store and find 2 similar pairs of eyeglasses. To get the right strength for each eye, close one eye and find the right strength for the open eye. Close the other eye, and read something else with the other open eye. With a tiny screwdriver, replace the lens with the appropriate one, and you're set. ex. one eye has 2.0, the other eye has 2.5 strength. Now you have 2 pairs of glasses!!
Each lens has to be the same exact shape and size (both left and right), or else you cannot have 2 pairs of glasses (only 1 pair if each lens have different shape).
