It is not possible to guard against the loss of opaque from the lens. However the risk can be reduced by the use of a 2-part peroxide solution and avoiding aggressive rubbing of the lens surfaces when cleaning.
In some cases we can attempt to re-opaque the lens at your own risk, should premature loss of the opaque occur within 3 months from the original order, providing the lenses are returned in good condition.
We are unable to re-opaque a lens if it has been stored or cleaned with any solution other than a 2-part peroxide system, due to the nature of the chemical processes involved.
We cannot guarantee to re-opaque any contact lens successfully and reserve the right to return the lens without re-opaquing.PIL/001 – Issue 2 – 01.07.09
