We all know that accommodative lag of around 0.50D is common, because depth of focus means that further accommodation does not improve subjective clarity, while vergence is generally accurate to within minutes of arc.
It is debated if in IXT the control of the deviation is mainly warranted by accommodation through the AC/A ratio or by fusional vergence through the CA/C ratio.
Visual performance at different vergences showed a similar behavior for both trifocal lenses, as expected.
To binocularly view an object of interest, two different types of eye movements are used: saccades and vergence. Saccades are rapid conjugate (version) movements used to orient the eyes toward a new direction by rotating the two eyes with similar angles.
Furthermore, knee folds exhibited relatively independent vergences relative to those of higher-order structures.
Measurements of fusional vergences at far and near for convergence and divergence showed better results for athletes.
Le [F.sub.1] est cause par la formation d'un pli ([F.sub.2]) non coaxial plus dominant, a vergence est et d'orientation NNE-NNO ainsi que par une schistosite de crenulation ([S.sub.2]) amplifiee en raison d'une dissolution par pression connexe.
Vergences are binocular movements where both eyes move in a synchronous and symmetrical, but opposite direction, that is convergence and divergence movements.
Two different target vergences were used: a target for distance and a target for near at reading distance (0.41 m).
5B) shows the Permian (Gondwanan) uplift of the western and central domains, with east- and westward vergences respectively.
During vergences, the innervations move the eyes in opposite directions; an innervation to initiate an ocular rotation of the right eye to the left (adduction, right MR) will be accompanied by an equal innervation to rotate the left eye to the right (adduction, left MR).
