The term for when lights appear blurry is called "halos."
Things in water appear blurry because the light passing through water refracts, or bends, due to the change in density between water and air. This refraction causes the light rays to scatter, resulting in the blurry or distorted appearance of objects when viewed underwater.
When you have trouble seeing things far away, it is called nearsightedness or myopia. This means that objects in the distance appear blurry or out of focus.
When you look at things up close, your eyes adjust by changing the shape of the lens to focus. However, when looking at things far away, the lens may not adjust properly, causing blurriness. This is known as nearsightedness, or myopia, where distant objects appear blurry.
Mirrors that give a blurry image may have imperfections in the glass such as scratches, warping, or a deteriorating reflective coating. These imperfections can distort the reflection and cause the image to appear 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.
Old Facebook photos may appear blurry due to compression and resizing techniques used by the platform to save storage space and improve loading times. When photos are uploaded, Facebook may automatically compress the image file, reducing its quality and causing it to appear blurry when viewed later on.
Farsightedness
This condition is known as myopia, or nearsightedness. People with myopia can see objects that are close to them clearly, but objects that are far away appear blurry. It occurs when the eyeball is too long or the cornea has too much curvature, causing light rays to focus in front of the retina. Myopia can be corrected with glasses, contact lenses, or refractive surgery.
Blurry vision can distort the clarity and sharpness of an image, making it difficult to see details and causing the overall image to appear unclear or out of focus.
Pictures on your Samsung Galaxy s3 appear to be blurry due them being compressed by your telecom provider being sent to your phone but if you turn on your WIFI the pictures will be sent directly to your phone and therefore most likely not blurry.
