Association between Refractive Error and Decreasing Visus in Pregnant Women [PDF]
, 2018 Background: Refractive error is a problem with focusing light accurately onto the retina due to the shape of the eye. The most common types of refractive error are near-sightedness, far-sightedness, astigmatism, and presbyopia.

Changes in forward light scatter parameters as a function of refractive error in young adults [PDF]
, 2020 Background/aims Some aspects of visual performance worsen with increasing myopia. Whilst the underlying causes are not always clear, reduction in retinal image quality is often attributed to structural changes in the posterior myopic eye.

JAMA: The Journal of the American Medical Association, 1895 These eighteen propositions will assist the beginner to more readily understand the many pages treating of the same subjects in all our text-books. With a second lecture on the lenses which correct the errors of refraction, and a third lecture on the frames which hold the lenses which correct the errors of refraction, we will have completed the "House
