Spots and floaters
People of every age may at times see spots and floaters, which appear to look like specks of material, cobwebs, thread-like strands or showers of brilliant crystals. During the middle years of life, they may become more frequent. These are optical defects that occur, as the vitreous, the jelly-like body in the main globe of the eye, becomes less jelly-like and more liquid as time goes by. This change is not always uniform, and so the mixture of jelly-like and liquid materials can affect the passage of light to the retina.
The result is seen as ‘floaters.’ Although spots and floaters are typically not of concern, they should be evaluated promptly. If you suddenly experience a large number of floaters, don’t delay in making an appointment. A sudden change may signify that something is wrong.
