This is because the images the brain receives from each eye are always blurred. A child with severe hyperopia can never see objects in detail. If the brain never learns to see objects in detail, then there is a high chance of one eye becoming dominant. The result is that the brain will block the impulses of the non-dominant eye. In contrast, the child with myopia can see objects close to the eye in detail and does learn at an early age to see objects in detail. Classification
Hyperopia is typically classified according to clinical appearance, its severity, or how it relates to the eyes accommodative status. Clinical classification
There are three clinical categories of hyperopia. Simple hyperopia: Occurs naturally due to biological diversity. Pathological hyperopia: Caused by disease, trauma, or abnormal development. Functional hyperopia: Caused by paralysis that interferes eyes ability to accommodate. Classification according to severity
There are also three categories severity:
Low: Refractive error less than or equal to +2.00 diopters (D). Moderate: Refractive error greater than +2.00 D up to +5.00 D.
High: Refractive error greater than +5.00 D.

Components of hypermetropia
Accommodation has significant role in hyperopia. Considering accommodative status, hyperopia can be classified as:
Total hypermetropia: It is the total amount of hyperopia which is obtained after complete relaxation of accommodation using cycloplegics like atropine. Latent hyperopia: It is the amount of hyperopia normally corrected by ciliary tone (approximately 1 diopter). Manifest hyperopia: It is the amount of hyperopia not corrected by ciliary tone. Manifest hyperopia is further classified into two, facultative and absolute.
Cervical effacement or cervical ripening refers to a thinning of the cervix. Background
Cervical effacement is a component of the Bishop score and can be expressed as a percentage.Prior to effacement, the cervix is like a long bottleneck, usually about four centimeters in length. Throughout pregnancy, the cervix is tightly closed and protected by a plug of mucus. When the cervix effaces, the mucus plug is loosened and passes out of the vagina. The mucus may be tinged with blood and the passage of the mucus plug is called bloody show (or simply "show"). As effacement takes place, the cervix then shortens, or effaces, pulling up into the uterus and becoming part of the lower uterine wall. Effacement may be measured in percentages, from zero percent (not effaced at all) to 100 percent, which indicates a paper-thin cervix. Results from a systematic review of the literature found no differences in cesarean delivery nor neonatal outcomes in women with low-risk pregnancies between inpatient or outpatient cervical ripening.Effacement is accompanied by cervical dilation. == References ==
