What does moderate visual impairment look like?
When the vision in the better eye with the best possible glasses correction is: 20/30 to 20/60, this is considered mild vision loss, or near-normal vision. 20/70 to 20/160, this is considered moderate visual impairment, or moderate low vision.
What are the three types of visual loss?
Common types of visual impairment
- Loss of Central Vision. The loss of central vision creates a blur or blindspot, but side (peripheral) vision remains intact.
- Loss of Peripheral (Side) Vision.
- Blurred Vision.
- Generalized Haze.
- Extreme Light Sensitivity.
- Night Blindness.
What is considered normal vision in Australia?
In Australia it is expressed as a fraction between 6/6 and 6/60 or less for either near or distance vision. The photographs in this booklet have been simulated to represent normal vision (6/6), moderate low vision (6/24), legal blindness (vision less than 6/60) and profound vision loss.
How much visual field is considered legally blind?
If you’re legally blind, your vision is 20/200 or less in your better eye or your field of vision is less than 20 degrees. That means if an object is 200 feet away, you have to stand 20 feet from it in order to see it clearly. But a person with normal vision can stand 200 feet away and see that object perfectly.
What is mild visual impairment?
When the vision in the better eye with best possible glasses correction is: 20/30 to 20/60 is considered mild vision loss, or near-normal vision. 20/70 to 20/160 is considered moderate visual impairment, or moderate low vision. 20/200 to 20/400 is considered severe visual impairment, or severe low vision.
What are the five levels of vision?
- Mild –visual acuity worse than 6/12 to 6/18.
- Moderate –visual acuity worse than 6/18 to 6/60.
- Severe –visual acuity worse than 6/60 to 3/60.
- Blindness –visual acuity worse than 3/60.
