Chris Bennett: Embrace the advances in optical technology

Those who follow optical technology will be well aware of the plethora of blue light lenses on the market and already protecting their patients from those worrying wavelengths of light nestling in the visible spectrum.

Those same early adopters will also be aware of the back pedalling, currently taking place among some lens firms, in recognition of the scale of the dangers and the way in which they have been presented.  Some may even be aware that tech firms have already developed screens to militate the need for such lenses. In short, optical technology is not closely followed, even by those who should be championing its cause.
