How Do the Eye Normally See Colors?
Our eye is one of the best sensory among other sensory organs by which we can see this beautiful world. Our eye is just like a camera. At the front of the eye, we have a lens that focuses images on the inside of the back of the eye. This area is called the retina, whereas, in the digital camera this material is made up of a semiconductor device.
20/20 is normal visual acuity is the standard for normal visual acuity. It means that one can see the object clearly in similar to what does an average person see. But 20/40 vision means what you can see at a distance of 20 feet (6.1 m), the average person can see that from 40 feet (12.19 m) distance which says your vision is half good as average persons. If vision is 20/10 then you can see the object at 20 feet (6.1 m) although the average person can see clearly at 20 feet (6.1 m) — thus your vision is twice good as the average person.
Recent digital cameras have 5-40 megapixels, but with 20/20 vision, the human eye is similar to or more than 52 megapixels camera.
A camera focuses on changing the distance of the lens and by changing the shape of the lens eye makes auto-adjustment by itself to focus properly. We see the colour of the object because the object absorbs some colours and it reflects the rest of the colors. By this reflected colour which falls on our eye, we verify the color of the object.
