"We believe we have done that now and this trial is good news for anyone with eyesight issues who wishes to play the game."
Only those goggles bearing the IRB trial-approved logo can be worn, with referees required to make the necessary checks.
"Features of the approved Rugby Goggles include high-speed impact resistance, anti-abrasion surfaces, anti-fogging, UV protection and a specially designed strap with no clips, buckles or sharp edges," Griffiths said.
"If the trial is to be instructive, we will require feedback from all participants who will be requested to provide feedback during and at the end of the trial."
Anyone wishing to wear the goggles will need confirmation that they are required to do so from an ophthalmologist (or similar medical professional) and unions are required to participate in the trial before a player under its jurisdiction can participate in the trial.
The approved Rugby Goggles, which cost €70 ($NZD 114) are not yet available from retail outlets and can only be purchased direct from the manufacturer's website.
