Why Do We See “Floating Flies”? The Medical Explanation That We All Should Know

The ocular phenomenon that worries many and how a specialist clarifies its causes and consequences

We have all experienced that sensation: we fix our gaze and small spots appear that seem to float in our field of vision. They have no concrete shape and seem impossible to catch. This phenomenon, popularly known as “floaters,” is one of the most common reasons for consultation in ophthalmology.

The ophthalmologist and surgeon José Miguel Caro, who shares health content on social networks, dedicated one of his latest publications to reassure those who feel alarmed by these spots. Although remember that a medical check-up is always recommended.

“Sooner or later, we are all going to notice 'flies' in our vision. They are those small lights or dark spots that are perceived mainly on light backgrounds, like when we read or look at the sky. I see them myself and they are part of the natural process of the eye,” Caro commented to normalize the experience.

The specialist explains that the eye works like a hollow sphere filled with a gelatinous substance called vitreous. With age, this gelatin loses water, similar to how our skin loses elasticity. “Small wrinkles are generated in the vitreous that, at first, are only observed in bright light conditions. These move and are comparable to the hairs that form wrinkles on the skin,” he explained.

At first, these structures are only perceived as fine “threads” floating in vision. However, Caro warns that it is time to consult a specialist if flashes of light or light spots appear. “As we age, the vitreous separates from the retina due to dehydration, and that is when we can notice flashes. Reviewing it with a professional is essential to rule out weakened areas in the retina,” he said.

If the ophthalmological examination does not detect any abnormalities, Caro assures that it is simply a natural process. “It is an adaptation mechanism: the brain needs time to ignore these spots. It can last several months, but eventually we will perceive them less or they will stop bothering us,” he concluded.

What are “floaters” and why do they appear?

• Dehydrated vitreous: The internal gelatin of the eye loses water over the years.
• Internal wrinkles: The loss of elasticity causes small fibers that float in the visual field.
• Light flashes: They arise when the vitreous partially separates from the retina.
• Natural process: Most of the time it does not indicate illness.

Warning signs to consult a specialist

In short, this phenomenon is common and usually benign, but constant observation and review with an ophthalmologist are essential to rule out more serious problems. Information and prevention are the best tools to maintain long-term eye health.

The contrast highlights the vitreous fibers and small internal deposits.

4. Can floaters be eliminated?
They are not eliminated naturally, but the brain learns to ignore them over time.

5. What is the main cause?
Vitreous dehydration and the formation of internal wrinkles with age.

6. Is treatment needed?
Only if symptoms change suddenly or affect vision, after medical evaluation.

7. How long does it take for the brain to adapt?
It may take months for the perception of spots to diminish.
