Abstract
The visual focusing and/or vergence abilities of a subject may be trained and/or tested using apparatuses and methods in accordance with the present invention. The subject may be provided with an apparatus having optical elements having different optical characteristics and instructed to look through an optical element having a first optical characteristic and to focus on an indicia or object. The subject may be instructed to rotate the apparatus and to look through optical elements having a second optical characteristic and to focus on the same or different indicia or object. The subject may be instructed to repeat this process with this or further apparatuses having optical elements having the same or different optical characteristics. The visual focusing and/or vergence abilities of a subject may thus be tested and/or trained.
