The difference between Optical and VisualEdit

Is there a difference between Optical and Visual? The definition of both seems to be "of or relating to sign"? Are they full synonyms or is there a nuance? Is there a time when you use one and not the other?--Maha Odeh 20:33, 26 August 2010 (UTC)

Good question. Optical is used to refer to matters related to handling the flow of light, including such things as fiber optics, lenses, eyeglasses, the flow of light in the human eye to the retina. Visual covers more the image that is produced by the light, eg, what happens after the light has hit the retina. We should make that clear in the entries. Don't the usage examples convey it?
