== Hyperopia, also known as farsightedness, longsightedness or hypermetropia, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short or when the lens cannot become round enough), causing inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. As an object moves toward the eye, the eye must increase its power to keep the image in focus on the retina. If the power of the cornea and lens is insufficient, as in hyperopia, the image will appear blurred.

What are other visual problems?
There are a lot of visual problems like, glaucoma.cataract,nystagmus,strabismus,retinal detachment, far sightedness and near sightedness.
What is an eye defect?
are conditions where a person cannot see distinctly and comfortably. There are three common eye defects, and they are(i) myopia or near-sightedness, (ii) Hypermetropia or far-sightedness, and (iii) Presbyopia. These defects are corrected by the use of suitable spherical lenses.
Why is it easier to see items at a far distance than close-up?
If a person can see things far away better than close up, this is called far sightedness. It has to do with the shape of the eye ball and the place in the eye that the image being viewed is focused in the eye. If the image focuses in front of or behind a certain point in the eye, it will cause far sightedness or near sightedness.
How is near and far sightedness be corrected?
Nearsightedness is normally treated with prescription eyewear.
What are the differences between long-sightedness and short-sightedness, and how do they affect one's vision?
Long-sightedness, also known as hyperopia, occurs when the eye is unable to focus on nearby objects. Short-sightedness, or myopia, happens when the eye struggles to see distant objects clearly. Long-sightedness can cause blurry vision up close, while short-sightedness results in blurry vision far away. Both conditions can be corrected with glasses or contact lenses.
What is the scientific term of hyperopia?
Hyperopia is the scientific term. The common term is far-sightedness.
What does wavefront surgery correct?
The wavefront surgery corrects eye vision. It is used to correct refractive errors near sightedness, far sightedness and astigmatism. It is used to give people better eye sight.
How are both near sightedness and far sightedness alike?
Both near-sightedness (myopia) and far-sightedness (hyperopia) are common refractive errors that affect how the eye focuses light. They occur due to the shape of the eyeball or the curvature of the cornea, leading to blurred vision at certain distances. Both conditions can be corrected with glasses, contact lenses, or refractive surgery, and they are often caused by genetic factors. Additionally, they can both lead to eye strain and discomfort when trying to focus on objects at specific distances.
What lenses would you use for short sightedness and long sightedness?
For short-sightedness (myopia), concave lenses are used to diverge light before it reaches the eye, helping to focus the image correctly on the retina. For long-sightedness (hyperopia), convex lenses are used to converge light before it reaches the eye, assisting in bringing the image into focus on the retina.
What is also called short sightedness?
gadha is also called short sightedness
What is near-sightedness?
myopia or "near-sightedness" as most of us refer to it is an eye condition.
How does nearsightedness and far sightedness differs in terms of defects and corrective lenses used?
