Myopia, also known as short-sightedness or near-sightedness, is a very common condition that typically starts in childhood. Severe forms of myopia (pathologic myopia) are associated with a risk of other associated ophthalmic problems. This disorder affects all populations and is reaching epidemic proportions in East Asia, although there are differences

Lancet, The, 2012 Myopia has emerged as a major health issue in east Asia, because of its increasingly high prevalence in the past few decades (now 80-90% in school-leavers), and because of the sight-threatening pathologies associated with high myopia, which now affects 10-20% of those completing secondary schooling in this part of the world.

Journal of the Optical Society of America, 1975
The basis for instrument myopia, the tendency to accommodate inappropriately while viewing through an optical instrument, was investigated in three experiments. The first demonstrated that the distance of a peripheral surround, analogous to a field stop, influences accommodation but that the magnitude of the effect cannot account for instrument myopia.

Epidemiology of Myopia, High Myopia, and Pathological Myopia
2021Myopia is a major health problem throughout the world due to its increasingly high prevalence in the past few decades. Myopia, in particular high myopia, is associated with a number of ocular complications such as glaucoma and cataract that are potentially blinding.

Optometry and Vision Science, 1981
Studies dealing with the development of myopia in primates are considered as they contribute to our understanding of myopia. Myopia appears to develop in two stages. The first is a lenticular change in eyes which have been focused at nearpoint for long periods; the lens remains continuously accommodated.

Myopia and orthokeratology for myopia control
Clinical and Experimental Optometry, 2019The prevalence of myopia in children is increasing worldwide and is viewed as a major public health concern. This increase has driven interest in research into myopia prevention and control in children. Although there is still uncertainty in the risk factors underlying differences in myopia prevalence between ethnic groups, rates in children of East ...

Night myopia is a correctable cause of decreased visual acuity under conditions of decreased illumination. Even people with 20/20 vision may have this problem. Correction of the decreased visual acuity in darkness may be especially important in certain occupations. Night myopia is related to the way light is refracted onto the retina.

Ophthalmologica, 1952
Night myopia for the left and right eye separately is studied with the aid of settings of a telescope using various test objects, brightnesses, pupil sizes, directions of fixation. Measurements of the visual acuity as a function of the ocular setting under variation of the parameters mentioned are included.
