| Precision work routinely
requires magnification to increase the visual size of
objects. As the eye |
| comes closer to an object, the
apparent size and detail is increased. However, the ability
of the |
| eye to focus correctly diminishes
at distance closer than 10" (254 mm). Use of a magnifier
provides |
| increased focusing power, resulting
in the visual effect of a clearer, larger image of the
object. |
