Vision and its Importance

The human eye is the sense of vision. An organ that plays a role of great importance not just in our lives but also in our body. It allows us in seeing all types of shapes, objects, colors and much more. We tend to perceive almost everything with our sense of sight. Vision is basically perceiving meaning from what our eyes see.

More than 50% or greater degree of visual-cognitive and visual disorders are present in neurologically weak patients, for example, those who have traumatic brain wounds, multiple sclerosis, cerebral vascular incidents etc. Let’s read more about TBI and vision issues. Much more is measured from visual acuity instead of just sight; vision is a process of making meaning from what you see. Involving a large number of abilities, this is a complex, developed and learning a number of functions.

This procedure of vision is broken down into three divisions; 1. Visual field and visual acuity, 2. Visual motor potential, 3. Visual perception.

  1. Visual Field – this is basically the peripheral range and complete central, or panorama of the vision. A bunch of neurologic conditions, for example, stroke, cause feature loss of visual field, such as hemianopsia. The suffering person might or might not demonstrate the visual neglect that is an intuitive loss of vision and the integration visual motor on the sides of visual field deprivation.

Visual Acuity – this mention the lucidity of sight. It is usually measured by using the Snellen note and chart, for example, 20/200, 20/20 etc. In diverse refractive cases, visual acuity gets blur, for example, hyperopia (farsightedness), presbyopia (age-related focusing loss), myopia (nearsightedness), and astigmatism (mixed).

  1. Visual Motor Potential – alignment; which refers to the eye postures. The straight and aligned posture of the eye is known as phoric. In case the eye is turned up, down, in and out as compared to the other eyes then they are not straight and aligned and this condition is called strabismus. When an eye gets turned up it is called exotropia which is one form of strabismus when the eye turns in it is esotropia, when the eye turns upwards it is hypertropia when the eye turns downwards it is hypotropia. These also occur in combinations, for example, hypo-esotropia or hyper-exotropia.
  2. Visual perception –
  • Integration Visual Motor: eye-foot, eye-body, and eye-hand coordination.
  • Integration Visual Auditory: the ability to associate and relating of what is heard and seen.
  • Visual Memory: the ability to recall and remembering information which is seen.
  • Visual Closure: the ability of ‘filling in the gap’ or completing a visual picture that is based on seeing just some parts.
  • Spatial Relationships: the ability to realize ‘where you are’ in relation to space around you and objects and where the objects are placed in accordance with one another.
  • Discrimination of Figure-Ground: the ability of an object of background and discern from.
