Detailed explanation-1: -Long sightedness (Hyperopia) As the name suggests, long sightedness means your long-vision (ability to see things in the distance) is uncompromised, while your near-vision (ability to see things up close) is blurry.
Detailed explanation-2: -Hyperopia is caused by the eyeball being too short or the cornea too flat. This causes the incoming light rays to focus behind the retina instead of directly on it. Long-sightedness is relatively common, affecting about one in four people with a refractive error. It can be an inherited condition.
Detailed explanation-3: -Farsightedness is a refractive error that makes nearby objects look blurry. It happens when the shape of the eye makes light focus behind the retina (a light sensitive layer of tissue at the back of your eye), instead of on it.
Detailed explanation-4: -What is Hyperopia? Some people see distant objects clearly, while some cannot even see nearby objects clearly. This is a result of the defects in the retina of the eye. People with hyperopia or hypermetropia are said to have far-sightedness or long-sightedness.
