Thanks lambada meant to thank you. I was waiting for the best answer. Apparently there is a place in POP called Optica Ouideo. On tuesdays there is a special on lenses and frames so I am told. However, the person I received this info from cannot verify this accuracy.
My doctor sent me last week to Optica Cibao in Santiago, telling me they are the best. In fact my glasses are perfect and the price was 3500 pesos less than in Puerto Plata for exactly the same which was a good surprise!!!! It is located just next to the shop El Encanto. As I could not go back on the next day to khem up, they sent them by Caribe Tours. Excellent service and very professionnal.
There are two places for Optica Cibao:
1) Thenew one on Av. Metropolitana at the corner of 5 St.
2) The original place on Duarte Street between Restauracion and Independencia, across from one side of el Encanto.
