Magnifying glass HTML5

In its simplest form, a magnifying glass is a single convex lens which causes the light from the object being observed to refract and converge on the eye. The enlarged image provided is sharp at the focal point of the lens where all the light rays converge. Microscope and telescope eyepieces are complex magnifying devices using several lenses.

The magnification illustrated is 2X.
