Prescription of spectacles, be such as used for the near lower plus light value for determining ophthalmology progressive lens.
Specifically, heterophoria is a kind of eye state, wherein eyes are in resting guard when without binocular fusion
The direction of sensing is inconsistent each other.People's (usual) with two normal eyes is due to feeling that the combination with Motion fusion system makes
With and with single eyesight.The effect of Motion fusion system is eyes is pointed to target interested, and visually detection is taken office
What skew (and the kinematic system is corrected)., just can be when left eye and right eye be separated only when eyes fusion is not present
Generation heterophoria.If a people covers an eyes (for example, using his/her hand), it can remove on eyes in track
On position sensory information.Without this, not to the stimulation of binocular fusion, eyes can be moved to " rest " position.
Difference between the position that this position and eyes are not covered is heterophoria.
Heterophoria almost can be all found on everyone, and simply degree is different, and depending on different situations.It is hidden oblique
Depending on generally asymptomatic.This be it is said that will be to its " compensation " when.When using fusion deposit to compensate hidden oblique, it is known that it is compensation
