Any convex lens bulges out from each side. It is thicker at the centre of the lens and thinner at the edges. I am supposing that a spherical convex lens has convexity on both sides, but on one of those sides the glass is so curved that it has the shape of part of a sphere.
Spherical aberration can be minimized by several methods: Changing curvature of both surfaces of a lens allows sharp focus at a particular distance. Aspheric lenses - i.e. lenses with a special non-spherical profile, is another.
A telescope uses a convex lens to gather and focus light, a concave lens to correct spherical aberration, and a flat mirror to reflect and redirect the light towards an eyepiece or sensor. These components work together to magnify distant objects and allow for detailed observations.
The spherical rock turned out to be a dinosaur egg.
The adjective spherical corresponds to the noun sphere.
The spherical ball rolled down the hill into the street.
An aspherical lens has a more complex shape than a spherical lens, which helps reduce optical aberrations like distortion and spherical aberration. This results in improved image quality with sharper details and better overall clarity.

Double-convex lens
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
No, the closer an object is to the lens, the more the spherical it is.
The word aperture does not apply to the lens itself. In a camera, the aperture is the diameter of the shutter opening which allows light to reach the lens.
The center of curvature of a lens is the point located at a distance equal to the radius of curvature from the center of the lens. It is the point where the principal axis intersects the spherical surface of the lens.
A piece of glass with one or two spherical surfaces is called a lens. Lenses are commonly used in optics to refract light and focus images.
The ciliary muscle, part of the retina of the eye, changes the focal length of the lens by flattening it or making it more spherical.
Spherical aberration can be reduced by using multiple lenses in a system or by using specialized aspheric lenses that correct for this type of aberration. Additionally, adjusting the curvature of the lens surfaces or using apodization techniques can help reduce spherical aberration effects in optical systems.
Using a spherical camera lens for capturing panoramic images offers advantages such as capturing a wider field of view, reducing distortion in the image, and providing a more immersive viewing experience for the viewer.
