We have long term patient that we have had wearing Sola Graduate 1.5 PGX progressive lenses, which have been chemically hardened.
We have recently put him into Varilux Comfort 1.6 PGX lenses, the Sola Graduate 1.5 PGX lenses being no longer available.
The patient has complained about the colour.
The Sola lenses give a blue-grey colour at maximum activation, whereas the Varilux lenses give a grey-brown colour.
The patient thinks we have given him PBX lenses, and might like his money back if we cannot give him the colour he wants!
We then tried some Rodenstock lenses (Pure Life), which give essentially the same colour rendition as the Varilux lenses.
Are the different colour renditions of these lenses due to the different indices (1.5 v 1.6), and does the age of the lenses (Sola Grads @5years old) and the chemical hardening also have some influence on this?
What other possible options do we have?
