Do ACUVUE lenses have an inside-out mark?
Put your ACUVUE® lens on your finger and look at the lens from the side. You should see the 1-2-3 written correctly. If the lens is inside out, the 1-2-3 will appear reversed.
The AV mark works in a similar way: If you place your lens on your finger and look at it from the side, you should be able to see the AV written correctly. If the lens is inside out, the AV will appear reversed.
