Flashes and floaters are symptoms of the eye that commonly occur as a result of age-related changes to the vitreous gel. When we are born, the vitreous is firmly attached to the retina and is a thick, firm substance without much movement. But as we age, the vitreous becomes thinner and more watery, and tissue debris that was once secure in the firm gel can now move around inside the eye, casting shadows on the retina.
Although flashes and floaters are common, especially as we age, it is important to see your doctor if you experience them, as they may indicate a retinal tear or hole. Your doctor can distinguish between harmless flashes and floaters, and those that may require treatment for an underlying condition.
Most flashes and floaters will become less noticeable with time as patients adjust their vision. Treatment of an underlying condition, such as a retinal tear, can help clear symptoms. Regular eye exams can help reduce the risk of complications.
