Prescription visor from Tag Heuer

Panorama is the latest addition to Tag Heuer's sport vision range.

Billed by the company as the world's first ophthalmic visor, the one-piece design offers 'unparalleled vision' combined with the 'very latest in high-tech ultra-lightweight materials'.

Panorama's wide curved lens offers a field of vision approximately 35 per cent greater than a classic rimless frame, said the company, and the prescription runs to the edge of the frame providing maximum field of vision.

The sides are made from beta titanium coated with an adherent rubber polymer that can be twisted to hold in any position.
