This paper generally discusses correlations between refractive errors and poor reading development. However, the relationships reported remain complex. Myopia is noted to correlate to high reading ability in some studies, but a correlation does not necessarily imply causation. Previous research in the field and deficiencies in the current literature base are discussed. Recommendations for the.

The study protocol was also approved by the local ethics committee. The protocol adhered to the provisions of the Declaration of Hel-sinki for.In 1997, the World Health Organization set itself an ambitious goal to eliminate avoidable blindness in the world by 2020, with one of the five main priorities being refractive errors. 1,2 A recent review of the impact of Vision 2020 on preventable blindness, other than uncorrected refractive errors, indicates that current estimates of global blindness are less than projected, and thus the.This paper discusses three core pillars to addressing the challenges posed by uncorrected refractive errors: Human Resource (HR) Development, Service Development and Social Entrepreneurship.
But research here shows that correcting vision significantly affects educational outcomes, said Dr. Congdon. Emmetropia and Myopia Through a process called emmetropization, the eye is programmed to grow just long enough for light entering the eye to be brought into focus on the retina (or slightly behind it, promoting mild hyperopia), said Prof. Congdon.
Refractive errors and refraction: How the eye sees. By Gary Heiting, OD. Schedule an exam. Find Eye Doctor. Blurry vision — usually caused by refractive errors — is the main reason a person seeks the services of an eye doctor. But what does it really mean when we're told that our vision is blurry because we have a refractive error? We see the world around us because of the way our eyes.
Prevalence of Refractive Errors in School Children. Introduction: Uncorrected errors of refractions have become one of the major important public health problems worldwide nowadays. They include myopia, hyperopia and astigmatism. Myopia (nearsightedness)is an ocular disorder in which the optical power of the eye is very strong for the corresponding axis. (1) It represents a major health.
Mr Konstantopoulos's research has predominantly focused on the clinical applications of optical coherence tomography imaging of the cornea. His work led to the award of a doctor of philosophy (PhD) degree from the University of Southampton. Current clinical research interests include: corneal imaging and quantification; refractive errors and.
Background: Refractive errors are a major cause of defective visual acuity in all age groups. Spectacles are the traditional and most widely used method of optical correction among all age groups. The main objective was to study the perception about refractive surgery among undergraduate medical students with refractive errors and their preferred method of refractive correction. Methods: A.
This research paper examines the five causes of vision loss: Cataracts, Glaucoma, Diabetic Retinopathy, Refractive Error, and Age related macular degeneration. Cataract Cataract is one of the most common eye diseases among the elderly. Cataract is an ophthalmic disease associated with clouding of the eye's lens and causing different degrees of visual disturbances.
Symptoms of refractive errors. In the event of a visual error, you will see clearly in either short or long distance. Some look unclear both in the short and long run. You may also have other symptoms of refractive errors such as feeling tired in the eyes, pee, blinking a lot and getting a headache. Different types of vision errors.

Research indicates that some 50%-80% of children with Down syndrome have refractive errors but the rate varies in different ethnic populations and tends to increase with age during school years. In infancy their vision is not different from other children. However, many typically developing children who have early refractive errors improve over time without treatment during the preschool years.
