Night vision CLs on trial

The lenses, developed by Professor Josef Bille at the University of Heidelberg department of Physics, Germany, are described as using a system similar to 'active mirrors', that are used in astronomical photography. Angela Rossi, lecturer in clinical optometry at the Institute of Optometry, London, who was quoted in an article in the Daily Mail on July 28, told optician: 'From what I have read about these lenses, my impression is that they are cast-moulded and probably aspheric or with faceted edges. 'They presumably work by reducing the aberrations associated with the increase in pupil diameter in dim light and may have an allowance for myopic shift.' The same article said that Bausch & Lomb was already carrying out clinical trials on the new lenses. A spokeswoman based at the company's US headquarters in Rochester, New York, said: 'Our research and development departments are aware of this work but currently are not researching this area. We see it as a very small market but will keep an open mind on the subject.'
