Legal blindness, defined as having a remaining visual field of 
degrees or less; low vision, defined as having a remaining visual field of 
degrees or less; and documentation from the student's doctor and school indicating that their vision is deteriorating over time and could eventually affect their ability to learn visually.
Depending on the type and degree of vision loss, the effect on learning will vary significantly. Some students may have been born blind, while others may have gradually lost their vision. Some may have no vision at all, while others may have some vision, be light-sensitive, or have restricted peripheral vision. Additionally, it's likely that day-to-day variations in vision and light sensitivity will occur.
