The eye is filled with a jelly-like substance known as the vitreous. Normally this is clear, but as we get older, debris can accumulate in the jelly. This appears as dots or threads floating across your vision in bright conditions. Floaters are usually of no concern, but if you notice a sudden increase in the number or if you see flashing lights, you should consult your optometrist immediately. In most cases no treatment is required, but if vision is significantly impaired the jelly can be replaced with an artificial gel. In some cases floaters can be “removed” using a laser.
