5 DEFINITIONS
D
IOPTER
:
This refers to the curvature of a lens.
With an increase in diopters, the lens becomes thicker and its curvature is bigger. With an
increase in the curvature, the rays of light sent to our eyes cover a larger portion of the
retina, which makes the object appear larger.
M
AGNIFICATION POWER
:
This refers to how large an object appears when looking at it through
a magnifying lens (see Figure 2).
