All the new members of Irelands High quality optical group, EyeZone, have banded together and decided to mark the launch of Irelands new optical group with a promotion of children’s eye health. And so at today’s launch of EyeZone all 131 participating opticians are offering free children’s vision screening all day Thursday (October 14), which is World Sight Day. This screening includes a high-quality vision test, developed by the Association of Optometrists, Ireland.
