The human eye is certainly a miracle of nature. It is so delicately vulnerable, yet highly sophisticated. Just how small can the human eye see on its own power, is a popular question. Browse the photos, illustrations and facts to learn more about one of our five senses, and how this magnificent body part sees little objects close-up and at great distances.
What you read here may amaze you. Many never learn how amazing the eye really is.
So, How Small Can the Human Eye See?
The quality of unaided visual perception differs from person to person based due to genetic differences between humans.
But in general, a healthy eye can see at remarkable detail.
Video: What is the Resolution of the Eye?
This is very entertaining and educational video from ‘Vsauce’ that gives commentary and many facts about how sharply humans can see with unaided vision. It is certainly worth a look to discover things you probably never knew before.
Optical acuity, visual observance, field of view, pixel densities, brain adjustments are all elements that contribute to how accurately our vision discerns small details. It is incredible how wonderful the gift of sight really is to humans.
We can see at remarkable detail with unaided vision. It just works differently than we may assume. View this video for more facts.
The Eye – Anatomical Illustrations
This scientific poster showcases detailed illustrations of the human eye, along with captions of text that explain many of its functions. Some of the anatomical components it details include sclera, retina, cornea, iris, crystallin lens and certain muscles. The bare eye sees small objects up close, and far-away objects that only look like they are of smaller size in different ways.
How Far Can the Human Eye See?
While our natural eyesight is very powerful, the distance we can see depends on several factors.
- Your current health
- Quality of your eye sight
- Amount of visible light available
- Current weather conditions
- The amount of light being emitted from object
