Can we see the dots of the eye vision resolution when our vision is blur?

Question

This is same as enlarge a image with small resolution in a computer until we see the pixel and it become blur....are the sharpness of the image seen affect by the resolution of the vision?Can we see the dots when vision is blur....?for e.g. myopia

Answer 1

The way the eye works is NOT the same as pixel resolutions. Blurred vision such as for myopia is due to the shape of eye and the shape of the lens such that the focus does not fall on the retina. It has nothing to do with resolution in the computing sense.

There's a good diagram here:

Answer 2

Human vision is a remarkable facility that involves focused light (billions of discrete photons of light) on a finite number of receptor cells of the retina capable of distinguishing color (cones) or B&W (rods), especially at night (night vision). The optic nerves (our largest bundle of nerves!) transmit snapshots to the brain in such rapid succession that we can interpret motion and depth. There are different layers of brain tissue that integrate colors and depth and even have "learned" to distinguish between round (curved) and straight lines that helps support optical illusions (what we expect to see!). There is a blind spot in every eye where the optic nerve is connected to the retinal but the brain fills in the gap. You can make a black dot on a sheet of paper "disappear" by positioning it to enter the blind spot. The image on the retina is upsidedown due to the lense but the brain unscrambles the message. The image is also reversed left-to-right but a dominant eye helps keep that straight. The image on each retina is divided by a vertical line through the center and half from each eye is sent to the left and right brain, but we can not "see" the parting line!

Unlike a digital camera (using pixels) the brain has learned how to see and fill in the blanks and what we see are illusions of the real world quite different from the vision of a dragon fly or frog. What does a clam see with its numerous eyes? Some people are completely or partially colorblind and see things very differently. What would our earth look like to a "Martian" or other alien? It is impossible to know.

To really answer your question you must study the inner workings of sight.

Stop asking the same questions over and over again. You have been reported.
