THE RELATION BETWEEN VISUAL ACUITY AND ILLUMINATION [PDF]
The Journal of General Physiology, 1928 1. Visual acuity varies in a definite manner with the illumination. At low intensities visual acuity increases slowly in proportion to log I; at higher intensities it increases nearly ten times more rapidly in relation to log I; at the highest ...

Unveiling Visual Acuity in 58,712 Four-Year-Olds: Standardized Assessment Defined Normative Visual Acuity Threshold [PDF]
VisionThe purpose was to define the threshold of normal visual acuity (VA), mean monocular and binocular VA, and interocular difference in the uniform cohort of healthy four-year-old children. All the children were recruited from the Croatian National Registry

THE VISUAL ACUITY OF THE HONEY BEE [PDF]
The Journal of General Physiology, 1929 1. Bees respond by a characteristic reflex to a movement in their visual field. By confining the field to a series of parallel dark and luminous bars it is possible to determine the size of bar to which the bees respond under different conditions and in ...

Investigative Opthalmology & Visual Science, 2018 Dry eye (DE) causes irregularity of the ocular surface and reduces the quality of vision. An intact, regular tear film is essential for high-quality retinal images; however, visual tasks requiring sustained gazing can disrupt the tear film, eventually degrading visual function.

Visual acuity assessment [PDF]
Eye, 1993 The immunopharmacological actions of nedocromil sodium are fully compatible with administration to man. Nedocromil sodium exhibits a wide range of anti-inflammatory actions. When compared with sodium cromoglycate, nedocromil sodium is more potent and a major difference is seen in the Ascaris-sensitised monkey subjected to bronchial challenge with ...

Estimating Visual Acuity Without a Visual Acuity Chart. [PDF]
Transl Vis Sci TechnolPURPOSE: This study explored whether visual acuity (VA) can be inferred from self-reported ability to recognize everyday objects using a set of yes/no questions. METHODS: Participants answered 100 yes/no questions designed to assess their ability to recognize familiar objects at typical viewing distances, such as distinguishing between a full moon and ...
