A percentage of the population is sensitive to black print on a white page, creating distortion whist reading and affecting their ability to learn and concentrate. Precision tinted lenses assist by alleviating the symptoms.

Symptoms of vision stress – all or some of:

  • Movement of print
  • Blurring of print
  • Letters changing shape or size
  • Letters fading or becoming darker
  • Patterns appearing, sometimes describes as “worms” or “rivers” running through print
  • Illusions of colour – blobs of colour on the page or colours surrounding letters or words
  • Rapid tiring
  • Headache, migraine or eyestrain

We use the Intuitive Colorimeter to determine the best precision colour tint to reduce visual sensitivity. The precision of the colorimetry instrument is used in conjunction with behavioural optometry techniques to achieve optimum results.

We do not diagnose dyslexia or attention deficit disorder, but where appropriate we can recommend strategies to minimise associated symptoms and difficulties.

Some people are more photosensitive than others, colour effect has been associated with metabolic and mitochondrial conditions such as migraines and fatigue syndromes. It is postulated that precision tinted lenses can reduce hyper-activation in the visual cortex of the brain.
