If power goggles, I've only seen TYR brand (if I am not mistaken). You have to purchase both sides separately and attach together (because people generally have different power for both eyes).

Price is generally expensive for power goggles, above RM40.

Ogival brand also have power goggles (cheapest brand) but water always enter into the goggles. If you tighten it to the max, it gets slightly better but will be painful. It is also sold in pair (for both eyes).
