Types of Floaters

Eye floaters are of different sizes, forms, uniformity and refractive index, which describes how light or any other emission reproduces organism and movement within the vitreous humor in the eyes. When a person is young the vitreous is perfectly clear, but with the passing years, faults slowly build up. The type of floater that affects most people is because of gradually worsening changes in the vitreous humor. Floaters can be seen because of the shades they throw on the retina.

Eye floaters are also visible by the distortion of light that moves past them, and they can emerge separately or in groups in a person’s line of vision. They might emerge as spots, or in very thin strips or remains of cobwebs which bit by bit drift before the eyes of the person. Since these substances are within the eye itself, they are basically not visual perceptions but are entoptic manifestations.  Floaters do not change, and the most pronounced can be seen for an entire lifetime.


Eye floaters are balanced inside the vitreous humor, which is the dense liquid that the eye is full of. Therefore, they usually track the quick movements of the eye while floating within the liquid. When a person initially becomes aware of them, he/she looks directly at them. But trying to move one’s line of vision may not be easy because floaters move with the movement of the eye, and stay to one side to the line of vision.  Floaters can be observed simply because they are not fixed inside the eye. Blood vessels also impede light, but they cannot be seen because they are inflexible in relation to the retina.

The brain does not absorb un-fluctuating images because of neural adjustments. This stability is usually broken up by eye floaters, especially when they can be seen. Floaters are prominent when a person’s gaze is fixed on a blank surface or an exposed single color object such as the sky, which is totally blue. Although they are called “floaters” most of these particles frequently submerge to the base of the eyeball in the direction the eyeball is slanting. The brilliance of daylight also reduces the size of the pupils, thereby dropping the opening which makes floater less fuzzy and easier to see.

What Causes Floaters

Usually floater occurs because of any injury to the eyes by which any foreign substance or material enters the eyes. Floaters could indicate a tear in the retina or the probability that the retina has been separated from its original position. However in 98% of the cases it is simply growing old which effects change in the vitreous humor. Although floaters have been linked to old age, they have been observed in children as young as 3 years of age.

It is more difficult to treat floaters in children and young people, because the floaters in this age group represent a crystal like form. They cannot be termed as genuine floaters technically because they are not present in the vitreous humor. However, they are present right above the retina in the premacular bursa.
