Visual Stress can occur under several
circumstances that must each be considered.
1) The need for corrective prescription lenses
or binocular vision anomalies (having eyes that are inappropriately aligned). In order to
discover if this is the cause it is always recommended that an optometrist be consulted to
rule out these conditions. If these are corrected, and there are still visual stress issues,
then precision coloured filters should be investigated. This can be done simultaneously and
prescriptions and tinting can be combined on one set of glasses.
2) Reading or working under poor lighting
conditions that are either too low or too high can cause Visual Stress. Changes to your
environment may need to be made to correct for lighting issues.
3) Where there is no other explanation but that
the images themselves create an unusually strong neurological response and result in Visual
Stress Symptoms. When screening for visual stress, a specific pattern glare test is used to
identify individuals who have a high neurological sensitivity to images and who may be good
candidates for relief through colour.
