A concave lens is thinner at the centre.
People who are short sighted often use a concave lens to help them see better.
A Concave lens is used to correct short- sightedness.
convex lens
A convexo-concave lens is a lens that has one side convex (outward bulging) and the other side concave (inward curving). This type of lens can be used to correct myopia (nearsightedness) by diverging light rays entering the eye.
A concave lens is a lens that is thinner at the center and thicker at the edges. It is used to correct myopia (nearsightedness) by diverging light rays before they enter the eye, thus helping to focus the image on the retina. Concave lenses are often used in glasses or contact lenses for people with nearsightedness.
A microscope typically uses multiple lenses, including both concave and convex lenses, to magnify and focus the light coming from the specimen being observed. The objective lens, which is closer to the specimen, is usually convex, while the eyepiece lens, which is closer to the observer's eye, is usually convex.
His glasses have a concave lens.

The melon was so rotten that it became concave when it was pressed on.
CONCAVE LENS : lens that atleast possess one end inwards is called as concave lens. CONVEX LENS : lens that atleast possess one end outwards like the exterior of the sphere is called convex lens. According to the medical values convex lens are used for long sight vision problem and concave lens for short sight vision problems.

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.
