Convex lens give a virtual & diminished image while concave lens give inverted virtual in rare case & magnified image.
The architectural term you are referring to is an "ogee." It describes a type of molding that has a profile featuring a concave curve flowing into a convex curve.
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 architectural term you are looking for is "ovolo." An ovolo is a classical molding profile that features a convex curve on the top and a concave one on the bottom. It is commonly used to soften the sharp edges of a door or window frame.
The human eye has a double convex lens in the cornea (outermost layer) and a bi-convex lens in the crystalline lens inside the eye.
Convex lenses are thicker in the middle then the edges and concave are thicker at the edges then the middle. When light travels through lenses, refraction occurs. The light bends either outward or inward, it depends on the lens.The lens of your eye is a double convex lens. Its job is to focus the image on the retina of the eye. If one is farsighted, the lens in the eye causes the focus to be behind the retina. These people see far but have some difficultly seeing close-up.To correct this farsightedness, the person would wear glasses or contacts with convex lenses, for It is often used for close examination of small objects.
Double-convex lens
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.

Convex lenses, also known as plus powered lenses, do cause light to converge. This type of lens is used on a Hyperopic (farsighted) patient. Concave lenses cause light to diverge and are used on Myopic (nearsighted) patients.
The human eye has a double convex lens in the cornea (outermost layer) and a bi-convex lens in the crystalline lens inside the eye.
Concave and convex lenses are curved lenses that bend light in a predictable manner depending on their radius of curvature and index of refraction. A concave lens bend inwards and a convex lens bends outwards.

with the help of convex lens we are able to converge the beam of rays to the fix point.
The difference between a double wide and a manufactured home is that the manufactured home is put on a foundation.
