Compound verbs, a highly visible feature of Hindi–Urdu grammar, consist of a verbal stem plus a light verb. The light verb (also called "subsidiary", "explicator verb", and "vector" [ 55 ] ) loses its own independent meaning and instead "lends a certain shade of meaning" [ 56 ] to the main or stem verb, which "comprises the lexical core of ...

Consequently, the eye must increase its refractive power to bring those rays of light together on the retina.
Form deprivation myopia occurs when the eyesight is deprived by limited illumination and vision range, [79] or the eye is modified with artificial lenses [80] or deprived of clear form vision. [81] In lower vertebrates, this kind of myopia seems to be reversible within short periods of time.
The human eye can function from very dark to very bright levels of light; its sensing capabilities reach across nine orders of magnitude. This means that the brightest and the darkest light signal that the eye can sense are a factor of roughly 1,000,000,000 apart. However, in any given moment of time, the eye can only sense a contrast ratio of ...
