Eye inflammation may not be painful. And the eyes are not usually as red as they are in conjunctivitis. So many children with juvenile arthritis who develop eye problems may not have any obvious symptoms.
It’s rare, but a child might complain of blurred vision or of light bothering their eyes. Sometimes, a child's eyes might look red or cloudy. But these types of symptoms usually develop so slowly that permanent eye damage can happen before they notice any trouble with seeing.
