I recently switched to soft extended wear contacts from RGP lenses. The brand my optometrist prescribed is Air Optix Night and Day.
According to some information online. All of these lenses have an "OK" indicator on them to tell if they are inside out.
My right lens has that OK indicator as well as a marking that reads "CIBA Z443"
However, my left lens doesn't have an OK indicator at all. It does have a marking that reads "CIBA Z447" instead.
I would think that if these were the same brand of contacts they would have the same markings and indicators on them.
Is it possible that I may have been given the wrong lens?
