wear glasses or some people are born with the ability to see things really close up.
Nearsightedness occurs when the physical length of the eye is greater than the optical length.
It's called myopia or nearsightedness.
Nearsighted
Depth of field decreases from low to high. This means what you see under the microscope is blurry. If both objects are not blurry, this means you have high depth-of-field.
Newborns see clearest between 8 to 15 inches from their face. They can see further but objects are extremely blurry.
An astigmatism means that the shape of the optics cause the focus to be a line rather than a point (the lenses are not spherical). Thus the image produced by these lenses is imperfect, causing a blurred image/vision.
unevenly curved
without glasses, everything is blurry
Such a person is called "far sighted".
Myopia: nearsightedness or rather distant objects appear blurry resulting from an eyeball that is too longHyperopia: farsightedness or rather near objects appear blurry while distant objects are clear, resulting from an eyeball that is too short aka "lazy lens"Astigmatism: images are blurry, resulting from the eyes focusing on lines not points, also due to unequal curvatures of the cornea or lensPresbyopia: a decrease in near visionSourceIntroduction to the Human Bodyby Gerard Tortora and Bryan Derrickson
A farsighted person can see distant objects clearly, but nearby objects appear blurry. The eyeball is too short, so the image that falls on the retina is out of focus. A convex lens corrects this by bending light rays toward each other before they enter the eye. An image then focuses on the retina.
Farsightedness
Being diagnosed as being nearsighted means just exactly what it says. You can only focus on things close to you. Distant objects are out of focus. Being farsighted means just exactly the opposite of being nearsighted. Distant objects are in focus, but nearby things appear blurry.
Mr. Myopic is a fictional character known for his nearsightedness or myopia, which is a condition where distant objects appear blurry. He is often used in educational materials to teach the concept of myopia and the importance of proper vision care.

like smudged or not visible clearly cloudy, fuzzy, hazy
A baby can see clearly at about 1 year. Babies are born legally blind, and their vision is very blurry.

It's because if the picture is smaller than your desktop (screen) then the pixels have to expand to fit the space, making it appear blurry.
