Colorimetry

If reading feels uncomfortable, words appear to move on the page or bright screens trigger headaches, our specialist colorimetry test in London could provide meaningful relief. At Adam Simmonds, we offer an advanced visual stress test in London using precision technology to determine whether tailored tinted lenses can reduce symptoms and improve visual comfort. To begin the process, arrange a full eye examination through our online booking page.

Colorimetry is the science of identifying the exact lens tint required to alleviate symptoms of Visual Stress, also known as Irlen Syndrome. This condition affects many individuals, including people with dyslexia, migraine sufferers, those with epilepsy and others who experience more than simple eye fatigue at the end of the day.

A colorimetry eye test in London involves the use of a specially designed instrument that presents carefully controlled lighting conditions. By assessing your responses to different hues, we determine the precise colour that reduces distortion and discomfort. The selected tint is then produced with exceptional accuracy by a specialist lens manufacturer. Depending on your symptoms, these lenses may be worn throughout the day or for specific tasks such as reading or screen use.

Before proceeding, we carry out screening tests to establish whether colorimetry is appropriate.

A visual stress test is particularly beneficial for individuals with dyslexia, though the scope extends much further. Increasingly, tinted precision lenses are helping people across a range of neurodiverse profiles, as well as those without any formal diagnosis.

Children who struggle with reading despite having no need for standard prescription glasses may benefit significantly. Visual stress is common among school age children, yet adults and individuals with autism also report improved comfort and concentration following a visual stress eye test.

Typical symptoms include words appearing to move, blur or double on the page, fatigue when focusing on text, sensitivity to bright light or high contrast screens and recurring headaches or eye strain after reading. These experiences can have a real impact on academic performance, productivity and confidence.

We use the latest Cerium Intuitive Colorimeter for every colorimetry test in London. This advanced instrument presents colours across 360 degrees of colour space, offering tens of thousands of possible combinations. Such precision is essential, as even subtle variations can significantly influence comfort.

The assessment lasts approximately 15 minutes and is straightforward to follow. It is entirely subjective, meaning there are no correct or incorrect answers. Reading speed can be measured both with and without the chosen filter to demonstrate measurable improvements.

Once the optimal tint has been identified, lenses are tinted and spectrally verified to ensure exact accuracy. A certificate of authenticity is issued, confirming that you are receiving genuine Cerium precision tinted lenses.

If you suspect that visual stress may be affecting your reading, concentration or comfort, the next step is to book a comprehensive eye examination. During this appointment, Adam will assess whether a colorimetry eye test is suitable and, where appropriate, carry out the full assessment. Book your consultation today and take the first step towards clearer, more comfortable vision.
