By definition an image is blurred if you cannot see things clearly due to a number of factors.
For example, Google Earth and Google Maps imagery can be blurred when a given area is at lower resolution than its neighboring area and appear "pixelated" when zoomed in too closely.
In some cases regions have been intentionally digitally obscured or blurred for a number of reasons. Google, for example, automatically detects licenses plates and faces in its Street View imagery and digitally blurs the pixels for privacy and security concerns.
Google Earth and Google Maps imagery becomes blurred often when a given area is at lower resolution than its neighboring area and becomes "pixelated" then zoomed in too closely.

The result is a blurred image
Depends on the resolution of the microscope.
The light so bright.
The image becomes blurred and it's size increases.
The desktop background on a PC will be blurred if it is at a much lower resolution than the screen is currently set to. This causes the image to be stretched and distorts it.
Its the myopia
The primary lens is to close to the specimen
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.

Otherwise the image formed will be blurred and mostly distorted. That is why we expect the surface of the mirror to be optically plane. Hence smooth.
When the light actually reaches the retina the image is blurred (except when looking at close objects when the image is focused on the retina and looks clear. The condition is known as short-sightedness.
the patient after implanting bionic eye can see only blurred image and need more practice else he can see only the dark and light spots
