Eye floaters and flashes: harmless, or a warning?

Almost everyone sees the occasional floater, those little specks, threads or cobwebs that drift across your vision and dart away when you try to look straight at them. Most of the time they are completely harmless. But occasionally they are the eye’s way of raising an alarm, and knowing the difference matters.

The usual, harmless kind

The inside of your eye is filled with a clear jelly. As we age, this jelly naturally becomes more watery and clumps a little, casting tiny shadows you see as floaters. They are most obvious against a bright wall or a clear sky. This is normal, and although they can be annoying, the brain usually learns to ignore them over time. No treatment is needed.

The warning signs that need same-day attention

Please be seen urgently, the same day, if you notice:

• A sudden shower of new floaters, many more than usual, appearing at once.
• Flashes of light, like lightning streaks at the edge of your vision.
• A dark shadow or curtain spreading across part of your sight.

These can be signs that the jelly is tugging on the retina, or that the retina has torn or begun to detach. Caught early, a retinal tear can often be sealed quickly. Left late, a detachment is far more serious. This is not something to wait and watch at home.

What we do, honestly

If you come in with these symptoms, we widen your pupils with drops and examine your retina carefully. If all is well, you leave reassured, and that reassurance is worth a great deal. If we find a tear or a detachment, we tell you plainly and, because retinal detachment surgery sits outside what we do here, we refer you quickly to a retinal surgeon we trust, so you get the right care without losing precious time. Being honest about what needs a specialist is part of looking after you properly.
