Depp's specs invented by Essex University professor
AN Essex University professor has been credited with inventing the technology behind the snazzy specs being sported by a Hollywood A-lister.
Film star Johnny Depp has been wearing blue-tinted coloured lenses for a number of years.
Depp has not revealed the precise health reason for the blue tint but it is believed to be to address Meares-Irien 'visual stress' syndrome, which causes dizziness, discomfort and eye pain.
Arnold Wilkins, professor at the university’s psychology department, devised the Intuitive Colorimeter - a machine that tests whether patient’s brains are sensitive to certain visual patterns.
But adding colour filters out the problematic ‘wavelengths’ generated to the brain.
The machine was so successful it has been rolled out to around 80 optometrists after it was patented nearly 20 years ago.
The lenses can be created in different colours using dye.
Asked about Johnny Depp wearing blue lenses, Prof Wilkins said: “He is one of many individuals who find tints useful.”
The treatment with the Intuitive Colorimeter is not available on the NHS in England but is in Scotland.
It is the only machine able to specify the precise tint of colour that sufferers need.
A “colour consultation” fee is normally around £75 – in addition to the
standard eye exam and prescription.
Professor Wilkins, who has been based at Essex University since 1997, has studied epilepsy and techniques for treatment which has led to research on vision and health.
