Cameras are amazing pieces of technology that can be used to permanently record what you see in nature or in your personal space. But no camera comes even close to being as good as your eye in seeing things.
In the days before smartphones, if you used a camera or a projector, one thing you
needed to do was to focus it, so that you got a sharp picture or image. This is to ensure that
every point on the object is matched by one point on the image, so the image is a clear
match. If one point on the object is matched by more than one on the image, the image
will be blurred.
Cameras, binoculars, and some telescopes have one or more lenses to focus light. Lenses
are curved pieces of clear material that bend, or refract light. Our eyes have lenses. And
we also have muscles that change the shape of our eye lenses from when we look at near
objects to when we look at things far away. This changes the focus of our eyes.
The biggest optical telescopes for looking at stars use curved mirrors to focus light by
reflection—bouncing light back to form an image inside the telescope. The reflecting
telescope was invented by the greatest scientist of all time, Sir Isaac Newton (1642–1727),
who was a creationist.
