Yes it is.

Concave is thinner in the center than the edges and convex lens is thicker in the center than on the edges :)

thinner in the center than around the edge
A convex lens
Yes it is.
A convex mirror is thicker at the center than at the edge, whereas a concave mirror is thinner in the center than at the edge.
Glasses for nearsighted people are convex. That is, the center of the lens is thinner than the outer edges.
You can't directly compare the two classes of lenses like that.What you can say is:-- The middle of a convex lens is thicker than the edge.-- The middle of a concave lens is thinner than the edge.One way to remember it: The middle of a concave lens is caved in.

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.
