Attached the first test scan, only of the frontal part without the temples

For the basic shape you're going to want to create a surface over the front face and then draw around the profile of the glasses, project this on your surface and delete the excess. Once you have the basic curved shape the extrude it by x mm (assuming it is consistent) and can add some rads to the edges. If the lenses are recessed you can make a cutter using a section of what you've already created.

You can do this in Spaceclaim/Rhino/Most other solid modellers (It can be done in Designspark but creating the front face is difficult as there are no blend/surfacing tools.) There's no point trying in a mesh program however, as you won't get consistent sharp edges. Depending how clean your mesh is, you may want to smooth the front face to be able to create a smoother surface.

This will all take you time to learn however. When I purchased my first scanner (and I was using CAD before this) I spent 6 months doing no paid work before I was comfortable taking on clients projects.
