Shes prob asking about it coz some say its normal and others say its not.
Ive been told and read that floaters are normal in most cases but they can be signs that a retinal detachment is on the way, and something you have t be careful of if you have high prescription lenses.
Normally floaters as far as i know are just like burst blood vessels...all blood vessels will burst at some time in everyone and they will show up in your eyes.
This is some info from the eye doctors that I go and see: Heres the website for more info:

Q
What is a floater?
TOP OF PAGE A
Floaters are relatively transparent, vague, usually curved objects that are seen best when looking at a white piece of paper, blue sky, light colored ceiling, or wall. They sometimes look like cobwebs, worms, rings, dots, or specks. Eye movement makes floaters more visible as they swirl about like seaweed in the ocean surf.
Q
What is the most common cause of floaters?
TOP OF PAGE A
They are usually caused by a clumping of pre-existing vitreous fibers in the eye. Therefore, doctors usually refer to them as vitreous condensations.
Q
What are some of the other causes?
TOP OF PAGE A
Some floaters are red blood cells or blood clots on the surface of the retina or floating in the vitreous. Such blood cells may occur with some retinal tears but do not necessarily indicate a tear. Occasionally, the vitreous can pull on a blood vessel on the surface of the retina and cause bleeding without causing a tear of the retina. Vascular disorders such as diabetic retinopathy and vein occlusion frequently result in bleeding inside the eye.
Rarely, floaters may be inflammatory in origin. Diseases such as pars planitis and uveitis can cause the formation of clumps of white blood cells (cells that the body produces when there is inflammation).
Floaters can also appear after a YAG laser capsule opening procedure (capsulotomy). After almost 50% of cataract surgery procedures that involve the implantation of intra-ocular lenses, the layer of tissue behind this lens becomes cloudy, causing a decrease in vision. The YAG laser capsule opening procedure is performed in these cases to place an opening in this "lens capsule", which usually results in better vision, but can also cause floaters.

Very common - Over 70% of the population experience these problems.
