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 age children under NHS provision.
Having ascertained that ocular problems are not the only cause of symptoms, an overlay assessment is recommended. An assessment with overlays is sometimes carried out in an educational setting, such as a school. A vision professional can also carry out this assessment. The patient may be prescribed a specific coloured overlay and asked to return after a sustained period of use should any improvements be noted.
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 lenses may then be prescribed as appropriate. The colour will be specific to each individual’s needs, much more precise than an overlay and may differ in colour to the overlay.
