Hello! I am interested in buying some prescription goggles for snorkelling when in Bali in July. I have checked the archive but there's not much there. Does anyone know how to go about it? I have a recent prescription for glasses and am assuming that I can use that goggles. Do you need to buy the goggles from a dive shop first and then go to an optical dispenser or should an optical dispenser have goggles to choose from? Any idea where would be best to go for this in Bali? And any idea of cost? Many thanks, Luke.
