"This is historically important because we've had past situations where people attempted to wear goggles which were not suitable. We contacted manufacturers and most felt there was no market in it so they were unwilling to invest — but Raleri collaborated. Our philosophy is simple. Anything worn must not damage the wearer or anyone who comes into contact."
Raleri boss Francesco Rambaldi said: "It's about providing something new in rugby's conservative environment. The hardest thing to develop was anti-fog technology; rugby is not as high speed as alpine sports so the goggles need to remain clear during high exertion, often for several minutes at a time."
Ian McKinley is a notable case study. The former Leinster first five-eighths retired aged 21 after going blind in one eye. His left eyesight was initially damaged in January 2010, when a team-mate accidently stood on his face. He recovered well enough to be offered a contract but blurred vision and further operations resulted in a detached retina.
McKinley played his first games using the goggles this month for Italian club Leonorso Rugby Udine.
He told the Daily Mail: "The goggles might cause a bit of debate and I'll also be wearing a scrum cap, so I'll sort of look like Batman, or maybe a pilot from the 1940s, but I don't care because I'll be playing. I'm treating it as a trial but it could be a good story for others with eye problems."
The cost of the goggles is €74 ($117). They will be available in retail outlets once the trial period is over and the IRB issue their full approval.
