To introduce the concept of the ray vector field and apply it to a problem in ophthalmic optics.
Matrix and linear algebra are used to relate ray vector fields and a representation of thin spherocylindrical lenses.
Equations were derived relating ray vector fields and a particular coordinate system recommended previously. The method is illustrated with a simple example from ophthalmic optics, namely, addition of spherocylindrical lenses. We also illustrate the method by considering two spherocylinders separated by a distance.
Ray vector fields are intuitively simple and can be used to solve complex ophthalmic optics problems.
