What does blindness or low vision mean? The definitions of low vision and blindness varies from country to country. In Aotearoa New Zealand, low vision is defined when your vision is 6/24 or less in your best eye with a correcting lens. That means that when your vision is corrected as much as possible, you will need to be at 6 metres to see what someone with 20/20 vision can see at 24 metres. You also qualify as low vision if your field of vision is reduced to 20 degrees or less, so when you look straight you can only see 20 degrees around without moving your eye.
