Our eyes are a true gift from God and a blessing upon us so we could this colorful world and the things in it. Eyes have very powerful natural lens which help to focus and view the things.
But still our vision has a limit and we can only focus on things that are close or else we cannot focus on things which are very smaller in size or microscopic.
Now, thankfully that scientists have discovered macro photography. It allows us to things clearly and more bright that are not visible to the naked eye.
