The groundbreaking text that highlighted the importance of the functional reality of low vision has been updated and expanded in this second edition.

In its original publication, this major resource advanced the understanding of the functional as well as the clinical implications of low vision and contributed to the expansion of services based on the individual's actual abilities, rather than on clinical measurements that conveyed only one dimension of an individual's needs.

Now, the revised second edition goes even further in the presentation of how best to assess and support both children and adults with low vision and plan programs and services focused on optimizing people's functional vision and ability to lead productive lives.
