“Is it normal for kids to see floaters?”

It can be normal, but in large numbers can be a sign of retinal or vitreous disease. An eye examination is indicated.

No. Most children do not see floaters. Perhaps he is describing a photic image when he looks away from a bright light. I would suggest that you have him evaluated by an ophthalmologist to rule out other causes of floaters in young children.

No. Floaters are usually caused by the gradual deterioration of Vitreous, a gelatinous material within the eye that fills most of the globe. It undergoes a gel to liquid transformation in the fourth to fifth decade of life, but can occur earlier if the eye suffers trauma. Then the Vitreous liquifies and leaves behind Vitreous condensations known as floaters. If the trauma, an elbow or finger thrust into the eye, or even a hard fall may cause this to happen. More of concern is that these floaters might represent a tear to the retina with blood cells or clots emanating from the portion of torn retinal tissue. Any and all of these findings need to be evaluated by a skilled retina specialist or competent ophthalmologist. Early diagnosis and treatment are essential for recovery if these more serious diseases are present.
Do not waste time, call an ophthalmologist immediately.

No.  The jelly part of the eye is too solid at age nine.  Take the child yo an ophthalmologist and get the observation  evaluated.  It may be nothing or the sign of a disease coming on.

They can, but it's a good idea to have him examined to be sure that there are no serious problems.

It is not normal for kids to see floaters. A check up is best.
