Light can be described in several ways depending on how you want to describe it, measure it, and what you want to do with it. The wavelength of light and other related properties are associated with physical optics. Geometric optics deals with ray tracing, the math of light, and its behavior with lenses and mirrors. Lasers and other devices utilizing light in various forms of energy fall into quantum optics (photons. Quantum optics utilize both wave and particle aspects to describe light. By definition, if the human eye is not perfect or emmetropic, then it has a refractive error or an optical aberration. Wavefront technology is a more specific way of detecting, describing, and measuring refractive defects. These defects include, but are not limited to, myopia, hyperopia, and astigmatism.
