Many of us have experienced the occasional small speck or shadow that briefly drifts across our field of vision. These are known as eye floaters, and in most cases, they are perfectly normal. However, when accompanied by flashes of light, or if they increase in frequency and intensity, it could signal something more serious. In this article, we will explore what floaters and flashes are, why they occur, and when it’s time to consult with an eye care professional.

What Are Floaters and Flashes?

Floaters are small, dark shapes that float in your vision. They might look like dots, threads, or cobwebs. Typically, they are more noticeable when you look at a plain, bright background such as a blue sky or a white wall. Flashes, on the other hand, appear as flickers or streaks of light, often in the periphery of your vision. They can occur in one or both eyes.

Why Do They Occur?

Floaters and flashes often occur due to changes within the vitreous, the gel-like substance that fills about 80% of the eye and helps it maintain a round shape. As we age, the vitreous slowly shrinks and can become somewhat stringy. The strands can cast shadows on the retina, the light-sensitive layer of tissue at the back of the eye, which we perceive as floaters. Flashes occur when the vitreous pulls on the retina. This tugging can stimulate the retina, causing you to see what looks like flashing lights or lightning streaks.

When Should You Be Concerned?

While floaters and flashes can be normal and usually aren’t cause for alarm, there are certain situations where they warrant more immediate attention:

• Sudden Increase: A sudden increase in the number of floaters, especially if you also see flashes, could indicate a retinal detachment, which requires urgent treatment to prevent permanent vision loss.
• Vision Loss: If shadows or grayness over part of your vision accompany your floaters or flashes, this could be another sign of retinal detachment.
• Persistent Flashes: Regular or persistent flashes may be a sign of retinal tear.

If you experience any of these symptoms, it’s important to seek immediate professional advice to rule out any serious conditions.

How Are Floaters and Flashes Treated?

In cases where floaters and flashes are not linked to any underlying condition, they are often left untreated and may lessen in intensity or frequency over time. However, if they are symptoms of something more serious like a retinal detachment, treatments such as laser therapy or surgery might be necessary to repair the retina.
