Key Points
- Visual impairment is the presence of a visual defect that is not correctable by prescription glasses or surgery1.
- Before meeting the doctor, prepare the relevant information and questions.
There are varying degrees of visual impairment: low vision, tunnel vision (which affects peripheral vision), or complete blindness. An individual’s type of visual impairment can affect the field of vision, level of detail and colours that they see.
The nature of visual impairment can vary widely:
- Complete or partial
- Sudden or progressive
- Central or peripheral
- Congenital or acquired
Your loved one’s psychological state, daily activities, functional needs and learning strategies may be affected, depending on their visual impairment. According to their needs, you can adjust the way you help them build functional skills.
Causes of visual impairment include cerebral abnormalities, eye cancer, diabetic retinopathy, cataract, glaucoma, stroke, and refractive errors
2. Visual impairment could also be a side effect of certain medications, such as steroids, which increases eye pressure. Check for
other risk factors and visit an eye doctor immediately if you spot something amiss.
Characteristics of visual impairment
Common indicators of visual impairment include:

- Older children experiencing blurred vision, seeing flashes, or having itchy or watery eyes
- Distorted vision (e.g., straight lines may appear crooked or wavy)
- Dark patches in central field of vision
- Flashing lights3
- Increased number of floaters, which are small, dark shapes that float across a person’s vision
