Visual Fixation Parafoveolar

Visual fixation Parafoveal is an incorrect way of focusing vision, in which the image of an object is projected onto the retina located in the area of ​​the macula, but does not extend beyond half the radius of this spot, i.e. closer to its center. This can lead to blurred vision and decreased visual acuity.

Parafoveal fixation of vision can be caused by various factors such as eye fatigue, refractive errors, myopia, farsightedness and other eye diseases. If you have vision problems, you should see an ophthalmologist for diagnosis and treatment.

With parafoveal fixation of vision, the image of an object is projected not onto the central part of the retina, but onto the periphery, which can cause distortions and difficulties in perceiving objects. It can also lead to eye fatigue and headaches.

Various methods can be used to treat parafoveal vision, such as glasses with correct vision correction, eye exercises, eye muscle massage, and others. Lifestyle changes such as eating right, getting enough sleep and regular exercise may also be required.

In general, parafoveal fixation is a serious visual impairment that can lead to serious consequences. Therefore, it is necessary to monitor your eye health and consult a doctor at the first sign of vision problems.

Visual fixation (or oculomotor responses) can be divided into two main types: parafocal and paracentral fixation. Parafocally, objects are projected beyond the fovea (at retinal parafocus). A paracentral point of view is a fixation on the superior part of the retina (just above the fovea) that disrupts the binocular integrity of the visual field. Apparent blackness results from blurring of the central image due to incomplete paracentric perspective; a person experiences symptoms associated with impaired color vision (color slip effect), although the disorders themselves do not appear. Unpleasant sensations in the visual field arise due to paralysis of the diaphragm, which is a combination of two muscles (ciliary and pupillary) that maintain active correspondence between the size of the pupil and the level of illumination in the fovea area.

With parafocal fixation, optical images are projected onto the peripheral zones of the retina or, in general, outside
