This page in a nutshell: Blurry images should not be used on Wikipedia. Wikipedia’s primary mission is to produce a “free” or “ libre ” encyclopedia of the highest quality. To that end, and with Wikipedia’s continued emergence as a leader in the field of collaborative research, it is becoming necessary to encourage editors to ...
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis ().

When refractive errors in children are not treated, the child may be at risk of developing ambylopia, where vision may remain permanently blurry. [33] Because young children typically do not complain of blurry vision, the American Academy of Pediatrics recommends that children have yearly vision screening starting at three years old so that unknown refractive errors or other ophthalmic ...

[4] [6] [7] At 2 degrees eccentricity, for example, acuity is half the foveal value. Visual acuity is a measure of how well small details are resolved in the very center of the visual field; it therefore does not indicate how larger patterns are recognized. Visual acuity alone thus cannot determine the overall quality of visual function. [8]
Another type of optical sight is the reflector (or "reflex") sight, a generally non-magnifying optical device that allows the user to look through a glass element and see a reflection of an illuminated aiming point or some other image superimposed on the field of view. [7] These sights have been around for over 100 years and have been used on ...
Blurred vision is an ocular symptom where vision becomes less precise and there is added difficulty to resolve fine details.. Temporary blurred vision may involve dry eyes, eye infections, alcohol poisoning, hypoglycemia, or low blood pressure.
