Ian McKinley has welcomed World Rugby's approval of goggles at all levels as the long trial run came to an end. 

The former Leinster back lost the vision in one eye following an incident during a club match with UCD when he was 20-years-old. 

The Dubliner retired from the game and moved to Italy to take up a coaching and technical role but was able to make a graduated return to playing by using specially adapted goggles to keep his good eye safe. 

The goggle trials began in 2014 and McKinley subsequently had spells with Viadana and Zebre and is currently playing with Benetton. 

The 29-year-old now has eight international caps for his adopted nation

"I'm delighted to hear that World Rugby have ended the trial period and made the goggles legal," he said. 

"Since I've started to use them I've managed to play Pro14, both European competitions and managed to play international level so they've been hugely important to my development. 

"It’s a massive day for kids as well if they need goggles from the protective side of things or to help with the vision."

World Rugby said in a statement: "The trial has enabled those with limited or no sight in one eye to participate in the sport more comfortably.

"This pioneering project was launched to address a specific issue, and with the help of Italy-based eyewear specialists Raleri, Ulster University and the University of Bradford, we have successfully developed a product that will enable more people to play rugby in a safe and comfortable way."

The sport's governing body also announced a trial of headgear. 

It said: "Reflecting its commitment to advances in player welfare, the World Rugby Council also approved a Law 4 trial to enable the assessment of headgear devices which, according to the manufacturers, have been designed to achieve specific, quantifiable medical advances, while aligning with Law 4 and Regulation 12 criteria. 

"Recognising the importance of assessing the evolution of technologies designed to manage and improve player welfare, trials will be permitted subject to strict criteria, including detailed evaluation by World Rugby, safety and independent test house assessment and shared trial research.

"While headgear is permitted in law on the basis that it does not cause harm to the wearer or an opponent, current research does not indicate a concussion prevention benefit and manufacturers should not make such claims."
