The primary use of Prentice's rule is that under certain circumstances, the prescribed prism can be obtained without grinding prism into the lenses, by decentering the lenses as worn by the patient.
The standard definition of convergence insufficiency is exophoria greater at near than at distance, a receded near point of convergence, and reduced convergence amplitudes at near. [4] See also [ edit ]

Far-sightedness primarily affects young children, with rates of 8% at 6 years old and 1% at 15 years old. [9] It then becomes more common again after the age of 40, known as presbyopia, affecting about half of people.

In order to fully understand evolutionary grades, one must first get a better understanding of phylogenetics: the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein ...

Colonization comprises the physical arrival of a species in a new area, but also its successful establishment within the local community. In ecology, it is represented by the symbol λ (lowercase lambda) to denote the long-term intrinsic growth ...
Even when the double vision images are made to nearly overlap using optical means such as prisms, the irregular movements prevent binocular fusion. The name horror fusionis (Latin phrase literally meaning "fear of fusion") arises from the notion that the brain is, or at least appears to be, actively preventing binocular fusion.
Invasion biology is the study of these organisms and the processes of species invasion. The terminology in this article contains definitions for invasion biology terms in common usage today, taken from accessible publications. References for each definition are included.
