HISTORY OF THE LENS
The existence of the lens for
controlling light dates back thousands
of years. Early lenses were made of
crystal or other transparent minerals.
One of the lens’ early functions was to
allow decorative ornaments to glow to
enhance their beauty. Later on, glass
lenses were invented and made into
eyeglasses for people to wear. The
type of material used for such lens
nowadays is acrylic. Plastic lenses
made of acrylic started being used less
than 80 years ago. Since acrylic plastic
is easy to make, lightweight, and
convenient to use, it has replaced glass
in the manufacturing of eyeglasses
and camera lenses.
Light
Light rays travel in a straight line through
empty space, and more or less in a straight
line through the air. They can travel very
long distances and reach remote places.
Because of this principle, we can clearly see
stars that are far away in outer space. Using
objects such as a lens makes it possible to
bend a ray of light. A straw appears to be
bent in a glass of water because the water
has bent the ray of light, not the straw.
Technologies that use prismatic lenses and
optical fibers to bend light for various
purposes are invaluable in the modern
world.
