Many of us have experienced the occasional small spots or flashes that drift through our field of vision, often visible when looking at a plain background like a blue sky or a white wall. These phenomena, commonly known as floaters and flashes, are usually harmless but can sometimes be a sign of a more serious eye condition.

What Are Floaters?

Floaters are small, shadowy shapes that appear in your field of vision. They can appear as black or gray dots, lines, cobwebs, or blobs. Typically, they are caused by tiny pieces of the eye’s gel-like vitreous breaking loose within the inner back portion of the eye.

• Age-related changes: As we age, the vitreous partially liquefies and can clump together, casting shadows on the retina.
• Posterior vitreous detachment (PVD): This common condition occurs when the vitreous gel pulls away from the retina, leading to noticeable floaters.

Understanding Flashes

Flashes appear as flickers or streaks of light in one or both eyes. They occur when the vitreous tugs on the retina. This tugging action stimulates the retina, causing you to see flashing lights or lightning streaks, even though there’s no actual light present.

When to Be Concerned

Occasional floaters and flashes are part of the eye’s natural aging process. However, there are times when they can be a sign of a more serious issue that requires immediate attention:

• Sudden increase in floaters: A dramatic increase in the number of floaters, especially if accompanied by flashes, could indicate a retinal tear or detachment.
• Loss of peripheral vision: Also described as seeing a curtain coming down over one eye. This could also signal a retinal detachment.
• Changes following eye surgery or eye trauma: If you’ve recently had eye surgery or an eye injury and you start seeing new floaters and flashes, it’s essential to consult your eye care specialist.

While not all situations with floaters and flashes require medical intervention, it’s crucial to have your eyes examined if you experience any of the above symptoms. Early detection and treatment are key in preventing potential vision loss.
