What does the compatibility guarantee mean?
There are sometimes incompatibilities with progressive lenses. Impression® progressive lenses are characterised by a considerably reduced rocking effects and a wide visual zone for close up. Among other things, this provides additional security when climbing stairs and leads to increased spontaneous compatibility. Therefore, even spectacles wearers who have had difficulties with conventional progressive lenses have very good chances of getting on well with Impression® ophthalmic lenses. However, if in spite of everything this isn’t the case, then the guarantee card provides a replacement free of charge.
