Problems solved by technology

Extensive reading by children and adolescents appears to cause progressive myopia.
Since increasing educational demands have increased the prevalence of myopia, optical correction, such as eyeglasses, contact lenses, and refractive surgery for myopia is a major health care expense.
Structures in this region of the eye tend to be stretched during development, and their integrity is compromised.
This causes greater risk to the effects of ocular trauma, diabetes, macular degeneration, and other diseases.
This means that myopia is also a major contributor to irreversible blindness.
This means that eyeglasses, contact lenses and refractive surgery are not treating the basic disorder, but are merely counteracting the effects of ocular elongation.

Embodiment Construction

[0027]The inventors have shown that myopic children and adolescents tend to under accommodate when looking at near targets during and prior to the period in which they are developing myopia. This under accommodation results in a myopigenic defocus similar to that which induces myopia in animal experiments. The inventors have also demonstrated that children and adolescents who are becoming myopic have certain binocular anomalies (near esophoria and high AC / A ratio) which tend to cause under accommodation (Gwiazda, J., Thorn, F., Bauer, J. and Held, R., “Myopia Children Show Insufficient Accommodation to Blur,” Invest. Opthalmol. Vis. Sci., 34, 690-694 (1993); Gwiazda, J., Bauer, J., Thorn, F., and Held, R., “A Dynamic Relationship Between Myopia and Blur-Driven Accommodation in School Aged Children,” Vision Res., 35, 1299-1304 (1995); Gwiazda, J., Grice, K., and Thorn, F., “Response AC / A Ratios are Elevated in Myopic Children,” Physiol. Optics., 19, 173-179 (1999) all of which are in...

Abstract

A method for at least one of preventing myopia and retarding the progression of myopia is provided. The method includes measuring optical aberrations in a human eye and correcting the optical aberrations. Measuring optical aberrations may include measuring wavefront aberrations of parallel light rays entering the eye.

Description

TECHNICAL FIELD[0001]The present invention pertains to measuring optical aberrations in the human eye and, more particularly, to preventing myopia and retarding the progression of myopia by correcting the aberrations.BACKGROUND ART[0002]Myopia (or near-sightedness) has become the most pervasive visual disorder in the world. About twenty-five percent of people in industrialized countries in the Western world, and more than fifty percent of people in industrialized Asian countries require optical correction for myopia. With increasing educational demands, the prevalence of myopia is increasing steadily. Extensive reading by children and adolescents appears to cause progressive myopia. Since increasing educational demands have increased the prevalence of myopia, optical correction, such as eyeglasses, contact lenses, and refractive surgery for myopia is a major health care expense.[0003]Myopia is due primarily to an elongation of the posterior pole of the eye during the school age year...
