how can we correct information the hypermetropia ?
Answers
Answer:
A person with hypermetropia/hyperopia or long sight can see clearly objects far away from them, but not close to them. This is caused by the shape of the eye - the eyeball is slightly too short. It is corrected by spectacles or contact lenses with lenses which are 'plus' or convex in shape.
Answer:
Hypermetropia (long-sightedness) is a common eye condition where nearby objects appear blurred, but your vision is clearer when looking at things further away.
If you feel your eyes are often tired and you have problems focusing on objects close to your eyes, you may have hypermetropia.
Causes
Your eye is like a camera. It focuses light on the back of your eye (on a place called the retina), which provides you with clear vision. Long-sight is caused by light not being correctly focused, with light travelling behind the retina.
One cause may be that your eyeballs are shorter than usual. This means that the retina is closer to the pupil, causing light to travel past the retina. A normal eye is usually around 23mm in length, so an eye that is hypermetropic will be shorter than 23mm.Alternatively you can also have hypermetropia if your cornea is flat. The cornea should be curved to direct light onto the retina.
Both of these factors cause long-sightedness, as they cause light to travel past the retina. This results in blurry vision, and can affect your daily life.
