Methods of management of attention disorders

A method for selecting a location of a correction coordinate in a device including at least one lens, the correction coordinate lies in the field of view of a subject, when the subject wears the device;

• the method comprising
• identifying on said at least one lens a correction region,
• wherein said correction region and said correction coordinate are each defined using a polar coordinate system measured from a lens center of the at least one lens, wherein the lens center is configured to be horizontally aligned with an optical center of a left eye or a right eye of the subject, when the device is worn by the subject;
• wherein said correction region has a two-dimensional double arc shape including a proximal arc and a distal arc, each of said proximal arc and distal arc face said lens center,
• wherein the proximal arc extends between a first proximal end and a second proximal end, and said distal arc extends between a first distal end and a second distal end,
• wherein the first proximal end and said first distal are connected by a first transverse line, and said second proximal end and second distal end is connected by a second transverse line,
• wherein said proximal arc has a proximal distance from said lens center that is between 4 mm and about 6 mm and said distal arc has a distal distance from said lens center that is between about 13 mm and 14 mm;
• and
• wherein a radial line connecting said first distal end to said lens center defines a first angle that is between 25° and 55° and a radial line connecting said second distal end to said lens center defines a second angle that is between 125° and 155°;
• and
• selecting said location of said correction coordinate in said correction region for placing thereon a correcting element for improving attention performance in a subject having attention disorder.

A method for converting an eyeglass into a device for improving performance of subject having an attention disorder, the method comprising:

• selecting a location of at least one correction coordinate on at least one lens of said eyeglass, for placing thereon a correcting element, said selecting comprises at least the steps of
• identifying on said at least one lens a correction region,
• wherein said correction region and said correction coordinate are each defined using a polar coordinate system measured from a lens center of the at least one lens, wherein the lens center is configured to be horizontally aligned with an optical center of a left eye or a right eye of the subject, when the device is worn by the subject;
• wherein said correction region has a two-dimensional double arc shape including a proximal arc and a distal arc, each of said proximal arc and distal arc face said lens center,
• wherein the proximal arc extends between a first proximal end and a second proximal end, and said distal arc extends between a first distal end and a second distal end;
• wherein the first proximal end and said first distal are connected by a first transverse line, and said second proximal end and second distal end is connected by a second transverse line;
• wherein said proximal arc has a proximal distance from said lens center that is between 4 mm and about 6 mm and said distal arc has a distal distance from said lens center that is between about 13 mm and 14 mm;
• and
• wherein a radial line connecting said first distal end to said lens center defines a first angle that is between 25° and 55° and a radial line connecting said second distal end to said lens center defines a second angle that is between 125° and 155°;
• and
• selecting said location of said correction coordinate in said correction region, the correction coordinate being within the subject's field of view when the eyeglass is worn by the subject;
• and
• placing said at least one correcting element in the selected location in said correction coordinate.
