What does blindness mean?

Answer: 

Total blindness is the inability to tell light from dark, or the total inability to see.

Visual impairment or low vision is a severe reduction in vision that cannot be corrected with standard glasses or contact lenses and reduces a person's ability to function at certain or all tasks.

If your vision has deteriorated to a certain level, you may choose to register as visually impaired. You will need to see an eye specialist (ophthalmologist). Depending on the severity of your vision loss you'll either be registered as sight impaired (previously "partially sighted") or severely sight impaired (previously "blind")

Your eye specialist will measure your visual acuity (ability to see detail at a distance) and your field of vision (how much you can see from the side of your eye when looking straight ahead). These measurements will help the eye specialist determine whether you’re eligible to be certified as sight impaired or severely sight impaired.

If you are, they will complete an official certificate with the results of your eye examination.

Your optometrist can advise you if you are likely to meet the criteria and refer you if appropriate.
