The recommended Colorimetry assessment process follows a 3 stage protocol:
It is essential that every individual who struggles to read or believes they may suffer from symptoms of Visual Stress first undergoes a full eye examination. This is important to rule out any ocular problems. This test is available free of charge for all school aged children under NHS provision.
Having ascertained that ocular problems are not the cause of symptoms, an overlay assessment is recommended. An assessment with overlays may already have been carried out in school. A vision professional can also carry out this assessment. The patient may be prescribed a specific coloured overlay and asked to return within a few weeks, noting any improvements.
Following successful use of a coloured overlay for a trial period, the Intuitive Colorimeter may be used to assess the patient under the direction of a vision professional. Precision tinted spectacles may then be prescribed as appropriate. The colour will be specific to each individual’s needs, much more precise than an overlay and very often a different colour to the overlay.
