Spherical lenses are easy to manufacture, but it has been identified by early opticians that using these lenses comes with aberrations on the image, called spherical aberrations. To compensate these aberration one can use doublets or complex systems of lens but this is costly and will take more space and weight.

What is an aspherical cameralensused for

The difference between both lenses comes from their shape, while a spherical lens shape can be defined from a virtual center and a fix radius of curvature, an aspherical lens shape is defined from a virtual center point point but with different values of radius of curvature according to their relative angle.

Aspheric lenses advantages disadvantages

For a simple image comparison, a spherical lens can be seen as a cut of a sphere whereas an aspherical lens can be defined by more complex shapes, for example conic or elliptic.

The other solution to remove the spherical aberration is to design the shape of the lens to avoid it, these complex shapes are defined by conical equation and are defined as aspherical shapes. Manufacturing of aspheres is more complex, but with recent (last 20 years) digitalisation of the production and testing equipment it becomes easier and cheaper.
