I had a patient who got progressive lenses from our place since 2009, the PD was 62, today he came in and got a pair of eyeglasses, he is a elder around age 75, I guess? The PD I got was around 65. Is it possible for the pd change? One of his eye is nearsighted, the other one is far sighted.

By the way, he has few pairs of eyeglasses, most of them are from our place, so I think keep PD 62 is better since he is gonna switch glasses. The lasted eyeglass he got was from last year. It was 62 Pd on file.

Thanks��
