There is a mobile eye care center that travels from town to town. Exams are free to all Dominicans who care to have their eyes checked. It has "computerized" equipment. I have been in one, and was quite impressed. There is a selection of new frames of all price ranges. For those who cannot afford those frames and/or lenses, the lions clubs around the country provide them, free. I know several people in the Guananico area with glasses courtesy of their local lions club.
As in any other country, eyeglasses, in the latest styles, are a status symbol. It is no different here. But, there are affordable and free services as well. Ask any Dominican in the Campo.
