Are my contacts interchangeable?

Question

The prescription is the same-- diopters and astigmatism. I only have 2 "rights" left, because I lost 2 "lefts".

Answer 1

If they're the same size with the same prescription they should be. Ask your supplier to be sure.

p.s. the astigmatism may be the same but is the axis the same?

Answer 2

Make sure all the parameters are the same. If the lens hasn't been worn it should be fine. Once you wear a lens in one eye it isn't a good idea to wear it in the other because if you come down with an eye infection you don't want to transfer it from one eye to another.

Answer 3

If all the numbers are the same, including the axis...then there is no problem using a right for the left.
