Myopia: Myopia is diagnosed by carrying out tests such as visual acuity, biometry, examination of eyeballs, eye lids and cornea, extra ocular muscle movement, slit lamp examination and fundoscopy. Hypermetropia : Diagnosis of hypermetropia is almost the same with Myopia as it is based on the symptoms and clinical signs observed.
What is the difference between myopia and hypermetropia?
Both myopia (short-sightedness) and hypermetropia (far-sightedness) are common eye conditions that occur when light does not focus on the retina properly. Both conditions are easily corrected using prescription glasses or contact lenses or, in mild cases, by laser eye surgery. Myopia is the term used to define short sightedness.
What is hypermetropia (far-sightedness)?
Hypermetropia is an eye problem where a person has difficulty viewing objects close to him, but can clearly see the objects located far away. This happens due to the light being focussed behind the retina instead of being focused on it. This condition is also known as far-sightedness, long-sightedness or hyperopia.
What is nearsightedness or myopia?
Myopia, or nearsightedness, is a condition where far-away objects appear out of focus. A common symptom of myopia is when you have trouble seeing things at a distance such as the board in school or street signs while driving. Myopia tends to be ignored at first as it is often confused with the objects being too far away to see clearly.
How is hypermetropia diagnosed?
Diagnosis of hypermetropia is based on the symptoms and clinical signs observed. The clinical signs include visual acuity, cover test, examination of eyeballs, eye lids and cornea, lens examination which may be dislocated backwards.

Hyperopia or Hypermetropia on the other hand, is an eye disorder which is commonly known as long sightedness, which means that this eye condition is the opposite of myopia. In hyperopia, items that are nearby appear to be blurry, while as far away things look normal.

What is Hypermetropia? Hyperopia or Hypermetropia on the other hand, is an eye disorder which is commonly known as long sightedness, which means that this eye condition is the opposite of myopia. In hyperopia, items that are nearby appear to be blurry, while as far away things look normal.
What is the difference between hyperopia and presbyopia?
Presbyopia is caused by a hardening of the lens and weakening of ciliary muscles over time, this is not usually the case for hyperopia Hyperopia and presbyopia are both vision conditions in which you can clearly focus on objects close to you, but can’t see objects that are far away from you.
What is the difference between myopia and hepermetropia?
The Difference: Myopia Vs. Hepermetropia (Hyperopia) Vs Presbyopia Myopia: Myopia is a type of refractive error whereby nearby objects appear normal and clear whereas distant objects appear blurry. Myopia is commonly referred to as Short – sightedness.
What causes myopia and hypermetropia?
Such a development could also happen because of age factor, as the ciliary muscles get more and more weak with growing age. In rare instances, hypermetropia may also be caused by high blood sugar (diabetes), as well as because of disorders with the blood vessels in the eye retina. Figure 1. Myopia and Hyperopia

These two are the “Refractive or Vision error”, where the image is formed at different sites (either in front or behind the retina) due to change in the size of an eyeball. In a myopic eye, the image forms in front of the retina and in a hypermetropic eye, the image forms behind the retina but not ‘on the retina’ as the normal eye.
What is the difference between hypermetropia and myopia?
The key difference between hypermetropia and myopia is that hypermetropia is a medical condition affecting the eye that makes it hard to see things that are close, while myopia is a medical condition affecting the eye that makes it hard to see things that are far away. Both the distance and near vision should be clear for proper vision.
What is myopia?
What is Myopia? More commonly referred to as near-sightedness, myopia is a condition where a person sees objects that are close to them clearly, but their long-distance vision is blurry. In someone with myopia, light enters the eye and focuses in front of the retina, instead of focusing on its surface.
What is the difference between myopia and farsightedness?
Both myopia (nearsightedness) and hyperopia (farsightedness) are refractive conditions — they refer to how light is focused in relation to the eye. Below, learn what myopia and hyperopia mean, as well as the differences between the two. The technical term for farsightedness is hyperopia.
What is the difference between myopia and astigmatism?
The following are some of the key differences between myopia and astigmatism: Myopia occurs when the axial length of the eye is elongated. While for astigmatism, it occurs when the cornea or lens of the eye is not perfectly smooth and round as it should be.

The characteristic difference between the myopic and hypermetropic eye is in the formation of an image: In a myopic eye, the image forms in front of the retina. In the hypermetropic eye, the image forms behind the retina. Oppositely, the image forms on the retina in a normal eye.
What is the difference between hypermetropia and myopia?
The key difference between hypermetropia and myopia is that hypermetropia is a medical condition affecting the eye that makes it hard to see things that are close, while myopia is a medical condition affecting the eye that makes it hard to see things that are far away. Both the distance and near vision should be clear for proper vision.
What type of lens is best for myopia and hypermetropia?
Both myopia and hypermetropia is a refractive error whose correction requires a different lens to correct these two conditions. Concave lens and convex lens recommends for the treatment of myopia and hypermetropia.
How does focal length affect myopia and hypermetropia?
The focal length of a lens is inversely proportional to the size of the eyeball, i.e. when the size of eyeball increases, the focal length will decrease and vice versa. Both myopia and hypermetropia is a refractive error, whose correction requires a different lens to correct these two conditions.
How does myopia affect the size of the eyeball?
The major effect is on the size of the eyeball, which increases in a myopic eye due to the decreases in focal length. Oppositely, the size of the eyeball decreases in a hypermetropic eye, which increases the focal length.
