There are true Rx googles you can get from the optometrist/optician, which are custom to your prescription but $$$$.
And then there are
corrective optical googles you can buy via
Amazon or swimshops which are more generic and only correct so much for $$.
I use the latter and they are "close enough for rock and roll", I wouldn't try and drive in them, but they work for on-and-off for a day around water parks and pools (I switch them out with my Rx sunglasses when not getting wet). If I were a daily swimmer, beach swimmer, or needed better vision, I would consider paying for a true pair for Rx goggles.
