Crizal — Crizal Prevencia Authenticity

Address:

Vasan Eye Care, Serilingampally, Hyderabad

Hello Crizal,

Ten days ago I visited Vasan Eye Care in Hyderabad and the doctor suggested me a pair of Crizal Prevencia.. I purchased it from their in-house store and they neither gave me the authenticity card nor did they mention Prevencia on the bill/receipt. I asked for it but they said they don't get it anymore from Crizal. With hesitation I came back home and when checked for authenticity, it reflects light green color under the tube light and when called the Vasan Eye Care, they say these are the recent improvisations that Crizal did to Prevencia glasses.. Is it so.. Can you pls confirm at the earliest
