The recommended Colorimetry assessment 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; visual stress screening is recommended as per the recommended protocol: Delphi Study – practical diagnostic guidelines for Visual Stress ₁
- Overlay assessment
- Wilkins rate of reading test
- Pattern glare test
Following successful identification of visual stress, the Intuitive Colorimeter may be used to assess the patient, under the direction of a vision professional, to obtain the level of precision required. The colour found will be specific to each individual’s needs, much more precise than an overlay and may differ in colour to the overlay.
Precision tinted lenses may then be prescribed as appropriate. All precision tinted lenses prescribed by a Cerium vision specialist following a Colorimetry assessment are tinted at Cerium’s specialist tinting facility. A certificate of authenticity is issued with every pair of lenses.
Optimal colours can change over time, so it is important to carry out an Intuitive Colorimetry reassessment at every eye examination to ensure optimal benefits.
