A spoon that you have put some food into is a concave shape. It is a cavity. A concave lens is such that it is thicker at the edges than in the middle.
Convex is the bottom of the spoon. A convex lens is thicker in the centre than around the edges.
A magnifying lens is typically convex in shape.
Your are mixing properties. Converging lens is always thicker in the centre and thinner at the edges. The other cathegory is the geometry of shape of the surfaces of the lens. Convex means that the shape is similar to the outer surbace of a sphere, concave means that the shape is similar to the iner surface of a sphere (or: convex = lower side of a spoon as we use it for sampling a soup; concave: upper (inner) shape of the spoon). A double convex lens is always a converging lens. A plano-concave lens is always a diverging (not converging) lens. A convexo-concave lens is the most usual shape of a lense used in spectacles. It can be either converging or diverging, depending on the radii of the surfaces.
The sheep's eye is concave, the surface of the shape of the lens are circular.
A convex lens is thicker in the center than at the edges. A convex lens is like a concave mirror.A concave lens is thinner in the center than at the edges.
When light rays enter a concave lens, they diverge or spread out due to the shape of the lens. The lens causes the light rays to refract, so they do not come together at a single point like with a convex lens. This spreading out of light rays is what makes concave lenses useful for correcting myopia or nearsightedness.
A concave circle
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
a shape of a lens is curved outwards and concave one are curved in wards

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

The eye itself is concave, meaning it is curved inward. The cornea and lens within the eye, however, are convex in shape.
The lens in a cows eye is flexible and clear. The flexible lens is able to change shape which allows it to better focus on objects.
