In the learning theory of Jean Piaget, the process through which a person's schema of understanding incorporates new experiences that do not fit existing ways of understanding the world.
See: adaptation The automatic process by which the eyes adjust their focus when the gaze is shifted from one point to another at a different distance.
It is expressed in dioptres, as the difference between the far point and the near point measured with respect either to the spectacle plane or the corneal apex or some other reference point.
Thus,where B is the near point vergence and K is the far point vergence. In the emmetropic eye, A = −B, because the far point is at infinity and K = 0.
We offer our guests accomodations in typical Russian wooden houses, heated with electricity or chopped wood, in traditional russian stove.
Unless you would prefer your own room, people tend to stay in rooms for two. We have houses with two rooms, as well as houses for larger groups. We charge 1000 roubles per hour until four persons.
Changes during accommodation: (A), contraction of ciliary muscles; (B), approximation of ciliary muscles to lens; (C), relaxation of suspensory ligament; (D), increased curvature of anterior surface of lens.4 (in sociology) the reciprocal reconciliation of conflicts between individuals or groups concerning habits and customs, usually through a process of compromise, arbitration, or negotiation. Occupational medicine The changes made by a person or organisation to a workplace to allow a person with disabilities to work there.
There are no discos here, but live music is always welcome !
Ophthalmology The automatic adjustment of the lens curvature, resulting in a change in the focal length of the eye, which brings images of objects from various distances into focus on the retina; the ability of the eye to focus at various distances, by changing lens shape.
Psychology In Piaget's theory of cognitive development, the change that occurs in an existing mental scheme or set of schemes due to assimilation of the experience of a new event or object. The adjustment of the eye for various distances whereby it is able to focus the image of an object on the retina by changing the curvature of the lens.
The ability of the eye to accommodate decreases with age.
Synonym: ocular accommodation; visual accommodation See: illustration4.
So, if the near point of an emmetrope is at 25 cm from the spectacle plane, the amplitude of accommodation is equal to − [−1/(25 ✕ 10)] = 4 D.
