A convex lens.
The convex lens are the converging lens. The periphery of the convex lens is thinner & the center part is thicker. In other words, the convex lens are bulging at the center & thinner at the periphery.

Concave is thinner in the center than the edges and convex lens is thicker in the center than on the edges :)
concave lens bends light rays away from the center
Glasses for nearsighted people are convex. That is, the center of the lens is thinner than the outer edges.
concave lens
A lens that is thinner in the middle and thicker at the edges is called a concave lens.
Goggle lenses don't have magnifying power because the front and back of the lens is curved the same. Lenses only have refracting (magnifying or size-reducing) power if the front of the lens is curved differently than the back of the lens. If the curvatures produce a lens that is thicker at the center than at the edges, then it will magnify. A lens that is thinner at the center than at the edges will be size-reducing.
