What is simple Hypermetropia?

Hypermetropia (hyperopia, long-sightedness or far- sightedness) is a form of refractive error in which parallel rays of light coming from infinity are focused behind the light sensitive layer of the retina, when the eye is at rest.

What are the types of hyperopia?

There are three types of hyperopia: congenital hypermetropia, simple hypermetropia and acquired hypermetropia.

  • In congenital hypermetropia one eye is abnormally small. This type of hypermetropia is not common.

Are you born with hyperopia?

Farsightedness usually is present at birth and tends to run in families. You can easily correct this condition with eyeglasses or contact lenses.

Most commonly, farsightedness is caused by a cornea (the clear layer at the front of the eye) that isn’t curved enough or by an eyeball that’s too short. These two problems prevent light from focusing directly on the retina. Instead, light focuses behind the retina, which makes close-up objects look blurry.

How much astigmatism is normal?

Moshirfar says. If you have less than 0.6 diopters of astigmatism, your eyes are considered normal. Between this level and 2 diopters, you have a small degree of astigmatism. Between 2 and 4 is moderate astigmatism, and above 4 is considered significant astigmatism.
