Colorimetry

At Hendry Opticians, our specialist colorimetry assessments are designed to help identify the precise coloured tint that may reduce visual stress and improve reading comfort. Using advanced assessment techniques, we provide personalised solutions, including coloured overlays and precision-tinted lenses, tailored to your individual visual needs.

Discover how colour may alleviate visual discomfort and visual stress

Visual stress is a term used to describe visual discomfort and perceptual distortions in the printed text, suffered by many people who struggle to read. It is estimated that up to 20% of dyslexic people experience visual stress and also the general population in varying degrees.

Colour has been known to make improvements to reading speed and accuracy. Colour overlays or tinted glasses or contact lenses may help enable longer periods of reading free of discomfort.

Is colour the right solution?

Eye examination

People who show signs of visual difficulty when reading should be referred for a full eye examination.

If symptoms of eye strain and/or visual stress are not helped by glasses, then an assessment of coloured overlays could be considered.

Overlay assessment

Our Optometrist can carry out an overlay assessment and may suggest that the patient try an overlay when reading for a few weeks, noting any improvements.

Colorimetry assessment

The Colorimetry assessment may result in precision tinted glasses being prescribed to the patient. The colour will be more specific to each individual's needs. This is more precise than the overlay assessment and very often a produces a different colour to the overlay. Using coloured lenses means any benefit is gained looking at screens and are therefore more convenient and more practical than overlays.
