Flashes and Floaters

Many people that develop flashes and floaters can get very concerned, and this is normal. Typically, floaters may appear as small specks or dark shadows. These specks can actually move or float around in the visual field. This condition develops from changes in the back of the eye also known as the vitreous cavity.


  • Sensitivity to bright lights
  • Specks floating in the central vision

In most cases, flashes and floaters are caused by age-related changes in the back of the eyes and further changes in the vitreous fluid (gel material). The vitreous fluid gradually becomes more viscous or watery over time. What happens after the age of 30 or so is that the vitreous might be watery enough to swallow clumps of material. This is how the floaters may develop. These clumps of material floating inside the eye can cast shadows on the retina and is why people see floating spots.

Diagnosing Flashes and Floaters

At Lexington Eye Associates, a comprehensive eye examination is conducted to determine if this is a serious issue or a relatively harmless condition. We will use very specialized diagnostic equipment to exam a person’s eyes and look for potential issues related to the retina.

Floaters can be a serious problem. However, in most cases, the problems are not serious. Please consult a retinal specialist at Lexington Eye Associates before trying to diagnose the severity of this condition.
