They can occur more frequently and become more noticeable as you grow older. If you notice a sudden change in the number or size of the spots, you should contact your Doctor of Optometry right away to be sure they are not the result of a more serious problem. The inner part of your eye is filled with a clear, jelly-like fluid known as vitreous. Occasionally, small flecks of protein and other matter become trapped during the formation of the eye before birth and remain in the vitreous body. Spots and floaters may also be caused by the age-related deterioration of the eye fluid or its surrounding parts, or by certain injuries or eye diseases.
Spots are generally translucent specks of various shapes and sizes.
They may also appear as threadlike strands or cobwebs within the eye. Since they are within the eye, they move as the eye moves, and often seem to dart away when you try to look at them directly. Most spots are normal and are not a cause of blindness. But, sometimes, spots can be indications of more serious problems, and if you see them, you should have an optometric examination to determine the cause. Your optometrist uses these instruments to examine the health of the inside of your eyes and may also observe the spots within your eyes.
