These skills are used to accurately interpret visual information and complete visual tasks as efficiently and effectively as possible. Students’ ability to interpret visual information is affected by many variables (e.g., the type and severity of vision loss, cognitive ability, experiential knowledge and environmental factors, such as lighting). However, with comprehensive, systematic training and practice, most students can learn to use their remaining vision more effectively and efficiently. Visual efficiency training may include blur interpretation, scanning and location skills, strategies to improve visual efficiency (e.g., use of appropriate lighting or wearing tinted lenses to reduce glare), and strategies which enhance a given student’s access to visual information. Students learn about their particular eye condition, its implications on access to visual information, and how to explain their visual needs to others.
