Britain became the first country in the world to benefit from Johnson & Johnson’s online Fitting Calculator this week.

The calculator helps match its 1-Day Acuvue Moist Multifocal contact lenses to presbyopic patients.

It was designed to quickly match patients to one of the 183 pupil-optimised designs offered by the lens, with the right match found by entering the best vision sphere or subjective refraction, sensory dominance and lowest near add.

It can be tried at www.jnjvision

John Meyler, senior director of worldwide professional affairs, said: ‘We hope that the simplicity of the Fitting Calculator helps eye care professionals offer a solution to patients that they may not have considered before.’
