Eye tracker
We use eye tracking software that monitors and analyzes the movement and focus of a person’s eyes. It utilizes specialized cameras and sensors to track the position, duration, and pattern of eye movements, such as fixations (when the eyes are still) and saccades (rapid movements between fixations).
In the context of children and school performance, eye tracking software can serve several important purposes:
1. Attention and Engagement Monitoring: By tracking where a child’s eyes are focused during classroom activities or while using educational materials, teachers and educators can assess their level of attention and engagement. This insight allows for targeted interventions to help children who may be struggling to stay focused or are easily distracted.
2. Reading Proficiency Assessment: Eye tracking software can analyze a child’s eye movements while reading, providing valuable information about their reading proficiency and comprehension. It can identify reading difficulties such as skipping words or lines, frequent regressions (re-reading), or difficulty with tracking from line to line.
3. Learning Disabilities Identification: Eye tracking technology can help identify potential learning disabilities such as dyslexia or attention deficit hyperactivity disorder (ADHD). Patterns of eye movements associated with these conditions, such as erratic scanning or difficulty maintaining focus, can be detected and used as indicators for further assessment and intervention.
4. Individualized Learning Strategies: By understanding how a child’s eyes move while learning, educators can tailor instructional strategies to better suit their needs. For example, if a child consistently struggles to maintain focus on written text, teachers can incorporate more visual or interactive learning materials to enhance engagement and comprehension.
5. Early Intervention: Early detection of learning difficulties or attention-related issues through eye tracking software allows for timely intervention and support. This can prevent academic setbacks and improve overall school performance by addressing underlying challenges before they become more significant.

Colourimeter
A colorimeter is a device used to measure and quantify the color properties of light, surfaces, or substances. In the context of Irlen Syndrome, a condition characterized by visual perceptual difficulties related to sensitivity to certain wavelengths of light, our colorimeter plays a crucial role in identifying and managing visual discomfort and perceptual distortions experienced by individuals with the syndrome.
Here’s how a colorimeter is important for diagnosing and helping people with Irlen Syndrome:
1. Color Precision: Individuals with Irlen Syndrome often experience discomfort or distortion when viewing printed text or digital screens due to their heightened sensitivity to specific wavelengths of light. A colorimeter precisely measures the hue, saturation, and brightness of light, allowing optometrists or vision specialists to identify the specific color filters that alleviate symptoms for each individual.
2. Customized Filter Selection: Based on the results of colorimeter measurements, personalized color filters are selected to address the individual’s visual discomfort. These filters, often applied to glasses or overlays, modify the wavelength composition of light entering the eyes, reducing perceptual distortions and improving visual comfort during reading and other visually demanding tasks.
3. Enhanced Reading Performance: By reducing visual discomfort and perceptual distortions associated with Irlen Syndrome, color filters applied using information obtained from a colorimeter can significantly enhance reading performance and overall visual function. Individuals with Irlen Syndrome may experience improved reading fluency, comprehension, and comfort, leading to increased academic or occupational success.
To correct for Irlen Syndrome using a colorimeter:
1. Assessment: The first step involves a comprehensive assessment conducted by one of our optometrists trained in Irlen Syndrome. This assessment typically includes a detailed evaluation of visual symptoms, reading difficulties, and perceptual distortions experienced by the individual.
2. Colorimeter Testing: During the assessment, a colorimeter is used to measure the individual’s response to different colors and wavelengths of light. The person views text or visual stimuli through various colored filters while the colorimeter quantifies their subjective experience of visual comfort and discomfort.
3. Filter Selection: Based on the results of colorimeter testing, specific color filters are selected to alleviate the individual’s symptoms of visual discomfort and perceptual distortions. These filters are chosen to match the individual’s unique visual needs and preferences.
4. Application of Filters: The selected color filters are applied to glasses lenses or overlay sheets, depending on the individual’s preference and requirements. The filters modify the wavelength composition of light entering the eyes, reducing the effects of glare, contrast sensitivity, and other visual disturbances associated with Irlen Syndrome.
5. Monitoring and Follow-Up: Individuals with Irlen Syndrome may undergo periodic monitoring and follow-up assessments to ensure that the selected color filters continue to provide effective symptom relief. Adjustments to filter color or intensity may be made based on changes in symptoms or visual needs over time.
By using a colorimeter to select and apply personalized color filters, individuals with Irlen Syndrome can experience significant improvements in visual comfort, reading performance, and overall quality of life
