A transparent, biconvex body of the eye between the iris and the vitreous humor that focuses light rays entering through the pupil to form an image on the retina. ... The focal length f is positive for converging lenses, and negative for diverging lenses. The reciprocal of the focal length, 1/f, is the optical power of...

A diverging mirror always produces an erect, diminished (m< +1), virtual image, located between the vertex and the principal focus (except if the object is placed on the surface of the mirror). ... The focal length (f) is positive for converging mirrors and lenses, and negative for diverging ones.

As long as the object is outside of the focal point the image is real and inverted. When the object is inside the focal point the image becomes virtual and upright. ... The image is always virtual and is located between the object and the lens.
