A. It is partly true.
Standard, run-of-the-mill pink eye that is caused by a bacteria, with a red eye and green or yellow discharge, doesn't usually lead to blindness. However, if your eye is infected with the herpes virus, then blindness could be a complication. Fortunately, herpes keratitis is much less common than regular pink eye. Children with this type of herpes infection, in addition to having a red eye, can have eye pain, sensitivity to light (photophobia), blurred vision, and excessive tearing.
If he continues to get pink eye so frequently, you likely should see a specialist to make sure that it isn't something more than regular pink eye. Unless everyone else in the day care is also getting pink eye at these times too, that may be a little more frequent than you would expect a child to get pink eye.
