Legally Blind

This is where your visual acuity does not exceed 6/24 in the better eye with corrective lenses, or you have serious limitations in your feild of vision generally not greater than 20 degrees in the widest diameter. This means, if you can't read a newspaper headline at arm's length with your glasses on, you may be eligible to receive RNZFB services.
