Unusual. Floaters that are benign mostly appear in older age groups related to changes in the character of the vitreous fluids in the back of the eye. In teenagers, floaters are quite uncommon and should be a cause, if new, for an evaluation by your ophthalmologist as soon as possible.
I have eye floaters in both eyes, have noticed them from being a teenager now in my early 30's, they seem more pronounced should I get them checked?
Yes. If there has been a change in your floaters, then an eye exam by an ophthalmologist is advised.
