I bought a pair for my mom from AquaGoggles
. The price was reasonable and they do ship internationally. They are good quality and she is happy with them.
Keep in mind these goggles won't correct for astigmatism. You have to pay a bit more for ones that do that. Still, they are good enough for me to have a rough idea of where I'm going even if the depth perception is a tad off.
