LENS. LENS. any transparent object having two nonparallel curved surfaces or one plane surface and one curved surface. Converging Lenses - thicker in middle than in the edge. These lenses converge light to a real focus. Diverging Lenses - thicker at edge than in middle. double concave.
LENS. It is a highly organized transparent spheroid structure that has evolved to perform refraction of the light entering in the eye. It does not posses nerve, blood vessels or connective tissue. . Anatomy of LENS. Biconvex Lens Diameter varies from 8.8 to 9.2 (9mm)
