Definition of Vision Impairment

Vision plays an important role in our growth, development, and daily performance.  Vision impairment is a term used to describe when an individual’s vision disorder affects the ability to function.

Some visual impairments can be corrected with eyeglasses. The two most common difficulties are myopia (nearsightedness) and hyperopia (farsightedness). The eye is still capable of serving as a major channel for information processing. However, individuals with severe visual impairments have difficulty seeing, even with glasses or contact lenses.

The visual loss is so severe that their eyes can no longer serve as a major channel for information processing.


Causes of Vision Impairment

Visual impairment may arise from conditions such as:

  • Genetic conditions (e.g. Usher's syndrome, Gillespie syndrome and Retinitis Pigmentosa)
  • Neurological visual impairment caused by a disorder or injury that affects parts of the brain that control vision (e.g. Cortical visual impairment (CVI), delayed visual maturation, and cortical blindness) 
  • Illnesses that happen to some premature babies (e.g. Retinopathy of prematurity) or babies that have particular problems during their birth (e.g.  paediatric glaucoma)
  • Age-related deterioration (e.g. macular degeneration)
  • Traumatic injury to the eye


Types of Vision Impairment

There are many different types of visual impairment, which results in a wide range of visual capacities, depending on the degree of their functional vision, visual efficiency, age of onset, effects of additional disabilities and the demands of their environment.


Symptoms of Vision Impairment

Possible signs of visual impairment include:

  • Rubbing eyes during or after short periods of visual activity
  • Bumping or tripping into things regularly
  • Difficulty moving around unfamiliar places
  • Difficulty coping and seeing in low light or bright light
  • Holding book too closely; placing face too close to surface, or sitting up close to technology 
  • Problems seeing in low light or bright light
  • Difficulty identifying faces, facial expressions or making eye contact
  • Trouble with identifying colours
  • Relying primarily on touch to find and identify items

Which resources are right for you?


Based on the Taking CHARGE of Rainbow of Emotions Workbook this app helps children of all ages develop emotional regulation skills. The app guides the child to firstly, identify and express their emotion in appropriate ways. Then the child is guided to use emotional management tool/s from the CHARGE tool kit to manage their emotions in a healthy way.

The acronym CHARGE stands for the different categories of emotional management tools – Chat tools, Helpful thinking tools, Amusement tools, Relaxation tools, Good routine tools and Exercise tools.

Behaviour Help App - Using the evidence-based approach of Positive Behaviour Support (PBS), the Behaviour Help web-based app allows people supporting individuals with emotional and behavioural difficulties to complete a Functional Behaviour Analysis and put together a comprehensive Behaviour Support Plan (BSP). The BSP can then be used by everyone interacting with the individual to manage and prevent challenging behaviours and ultimately improve their lives, and the lives of those who support them.
