Signs and Symptoms
A visual impairment affects a person’s sight and their ability to interact with the world around them. Legal blindness occurs when the person cannot see at 6 metres what others see at 60.
A person who is completely blind has no measurable vision and light perception. Others have vision loss that cannot be corrected through aids such as glasses. Impairment can occur from birth or can develop and can also affect depth and colour perception. They can include;
Cataracts - the clouding of the clear lens in the eye causing blurred vision, glare sensitivity, distortion or the feeling of looking through a veil.
Cortical Vision Impairment - is caused by the disturbance of the visual cortex of the brain. The eyes may function normally but the brain does not interpret what the eyes see. This can be caused by lack of oxygen to the brain, head injuries or infections in the central nervous system.
Glaucoma - is an eye disease that affects the optic nerve connecting the eye to the brain. Glaucoma is often caused by a blockage in the eye’s drainage system. Symptoms include blurred vision, loss of peripheral vision and difficulty adjusting to low light.
