Flashers and floaters are common visual symptoms that many experience. Understanding these phenomena is crucial for maintaining your eye health and recognizing when to seek medical advice.
Flashers and floaters are common visual phenomena that many people experience at some point in life. They may appear as small specks, squiggly lines, sudden flashes of light, or even brief bursts that catch your eye. Although these occurrences are usually a normal part of aging, they can sometimes signal more serious conditions that warrant an evaluation by our eye doctors.
Both flashers and floaters develop within the eye’s vitreous chamber, a gel-like substance that fills the space between the lens and the retina. They are the result of natural changes that occur over time, but can also be associated with other eye conditions. Here’s a closer look at what these distractions in your vision mean and why staying informed is important.
Eye floaters, sometimes known as vitreous floaters, are tiny spots or shapes that drift through your field of vision. They can resemble dark dots, squiggly lines, spiderwebs, or even strands that shift as your eyes move. Floaters are created when the collagen fibers within the vitreous humor begin to clump together. As the vitreous slowly liquefies and shrinks—a natural part of aging—these clumps become more noticeable. They might look like particles suspended in your vision, much like dust on a windowpane, and while they are typically harmless, their sudden increase may require further evaluation.
Eye flashes, often referred to in medical terms as photopsias, are brief bursts or streaks of light that appear in your field of view. Unlike floaters, flashes occur as a result of the vitreous gel tugging or rubbing against the retina. As the vitreous shrinks with age or due to other factors, it can pull on the sensitive tissue at the back of your eye, resulting in a flash of light. These flashes might appear as sparkles, a brief flicker akin to lightning, or even a flash reminiscent of a camera burst. Although they are usually benign, a sudden escalation in frequency or intensity should not be ignored.
The majority of flashers and floaters occur naturally with aging, but there are several conditions and factors that can increase their likelihood. Understanding these causes is key to knowing when to monitor your symptoms at home and when to consider an evaluation by our eye doctors.
As we age, the vitreous humor naturally begins to shrink and become more liquid. This process, known as posterior vitreous detachment (PVD), is the leading cause of both flashers and floaters in older eyes. With PVD, the gel inside the eye gradually pulls away from the retina, resulting in the brief flashes of light as the retina is stimulated. Although PVD is generally a harmless and normal part of aging, it can sometimes lead to more serious conditions, such as retinal tears or detachments, if the pulling becomes too forceful.
While aging and PVD are the most common culprits, several other factors may contribute to the formation of flashers and floaters:
These contributing factors highlight the importance of regular eye exams, especially when you notice a sudden increase or change in these visual disturbances.

Identifying the nature of your flashers and floaters is an important step in determining whether they are part of a normal aging process or a sign of something that might require further attention. Knowing what to look for can help you have a more fruitful discussion with our eye doctors.
Flashers often appear as brief, sudden bursts of colored light or white flashes. They usually occur in the peripheral field of vision and can resemble small stars or lightning streaks. These flashes are ephemeral and typically flare up when there is a pull on the retina. It’s important to note that while isolated episodes can be harmless, frequent or persistent flashes should be taken seriously. They might be a signal, albeit often a benign one, that changes are occurring in the vitreous gel. However, if flashes are accompanied by other symptoms such as blurred or distorted vision, this could indicate a problem such as retinal tear or detachment that needs prompt consideration.
Floaters present themselves as small specks or strand-like shapes, which can range from dots or squiggles to cobweb-like structures drifting across your view. They are most noticeable when looking at a uniform, bright background such as a clear sky, a light-colored wall, or a white paper. As your eyes move, so do these floaters, often shifting out of your primary field of vision. They may settle near the bottom of your field when you are not looking around actively. While many people learn to live with floaters, a sudden increase in their number or density can obscure your vision just enough to be worrisome.
Most flashers and floaters are benign, but sometimes a sudden increase or change in these symptoms can indicate something more serious. Our eye doctors always recommend staying alert to any related changes in your vision.
If you experience any of the following symptoms in combination with flashers or floaters, it is important to contact our office immediately:
The combination of these signs, especially when they occur suddenly, can be an indication of retinal tears or detachment. Retinal detachment is a serious condition that can lead to permanent vision loss if not treated promptly.
