Swedish goggles are the solid plastic type with no rubber cushioning (gasket) around the edges. Raved about by those for whom they work because they're simple, cheap and because there is less rubber involved they last longer in chlorinated pools.
Given that they offer no gasket between the goggle and the eye socket, they can be tough at first as they'll press more than you are used to. That said, I bought a pair and found that the curved profile of the goggle just did not match my eye at all, so no matter how tightly I strapped them on, they were useless. Not a big cost to try them, though....
