That branch of actual research which treats associated with nature and properties of light, the rules of their adjustment by opaque and transparent systems, and the phenomena of sight.
That branch of physical research which treats of this nature and properties of light, regarding the principle of colors (chromatics), for the modification which light suffers either in its attributes or in its program when refracted or sent through bodies (dioptrics), when mirrored from their surfaces or when driving near them (catoptrics), regarding the structure of this attention and the legislation of vision, and of the construction of devices of introspection, as telescopes, microscopes, etc.
the part of physics that studies the real properties of light
