Almost everyone gets occasional specks in
front of their eyes. These specks are known as eye floaters and are especially
common when looking directly at a light background, or when feeling
light-headed. The perception of floaters is medically known as myodesopsia.
Floaters are tiny dark specks that can be
seen in your field of vision, especially when you look at a blue sky, a white
wall or any other uninterrupted, light coloured expanse. They are created when
tiny clumps form in the clear, jelly-like substance (the 'vitreous humour')
inside the eyeball.
As these tiny floaters are suspended in this
'jelly', they move when your eyeball moves. As a result, if you try to look
directly at them, they may appear to disappear from sight.
Floaters can come in different sizes and shapes.
Some look like little dots, while others appear like threads or little hairy
clumps. In most cases, floaters are normal and harmless. However, a sudden
increase in their number may indicate damage to particular internal structures
of the eye
