Flashes and Floaters

Ever see those fleeting flashes of light or shadowy specks that drift across your vision? These are called flashes and floaters, and while they can be startling, they're often harmless. However, in some cases, they can be a sign of a more serious eye condition.

​

  • Flashes: These appear as streaks of light, lightning bolts, or shimmering objects in your central vision. They usually last for a few seconds and can occur in one or both eyes.

  • Floaters: These appear as cobwebs, strands, dots, or rings that float across your field of vision. They are more noticeable when looking at a bright background, like a clear blue sky or a white wall.

Causes of Flashes and Floaters

The most common cause is a natural change called posterior vitreous detachment (PVD). The vitreous is a gel-like substance that fills the center of your eye. As we age, the vitreous can detach from the retina, the light-sensitive layer at the back of the eye. This pulling or tugging on the retina can stimulate light signals, causing flashes. Sometimes, small clumps of gel can break off and float around in the vitreous, appearing as floaters.

​

In some cases, flashes and floaters can be a symptom of a retinal tear. A retinal tear is a small break in the retina. While not always serious, a retinal tear can lead to a retinal detachment, a more serious condition requiring immediate medical attention.

Flashes and Floaters Diagnosis and Treatment Options

While floaters are often harmless, especially if they occur occasionally and don't worsen, it's crucial to seek professional help in certain situations:

​

  • Sudden Onset of Flashes and Floaters: If you experience a sudden increase in flashes and floaters, especially accompanied by a dark curtain or shadow moving across your vision, see your optometrist immediately. This could be a sign of a retinal tear or detachment.

  • Large Floaters or Many New Floaters: A sudden appearance of many new floaters, especially large or accompanied by flashes, warrants a visit to your optometrist.

  • Loss of Peripheral Vision: If you experience any loss of peripheral vision (side vision), consult your optometrist promptly.
