Interesting BrattishTaz... I'll have to look closer. A little background ... My 20y/o son has been almost totally blind in his right eye since birth,due to a genetic issue. The important part of this is that every pediatric ophthalmologist stressed to the 'enth degree... To protect the other eye. Their point was well taken and Keith always had protective lenses on. Even if they were awkward and dorky. We are so grateful that we were encouraged to go the extra mile to keep his other eye protected. A fling of a rock, a broken twig or bad bounce baseball. You just never know. It's great that your son is not afraid' but encourage his to protect his eyes. The chicken has given you notice... sorry for the intensity, this is very close to my heart.
