Eye floaters are a common but often misunderstood visual phenomenon. It’s essential to understand what causes them and when to get medical help. Here’s what the experts say you should do.

Floaters are typically caused by age-related changes in the vitreous, a gel-like substance that fills the eye. As we get older, the vitreous becomes more liquid, and the tiny fibers within it can clump together, causing shadows on the retina. These shadows are what we call floaters.

But sometimes, they can be a sign of more serious health problems, like:

Problems in your eyes

Uveitis occurs when the inner layer of your eye becomes inflamed.

Tears or detachment of the retina.

Some people are more likely to experience floaters. You might be more at risk if you:

Are they short-sighted?

I’ve had an operation to remove my cataracts.

If you have diabetes, you are at risk of developing diabetic retinopathy.

Getting older

They are usually harmless, but if you experience a sudden increase in floaters, flashes of light, or a shadow appearing in your peripheral vision, it could signal a retinal tear or detachment. These are medical emergencies and require immediate attention.

Eye doctors use a special test called a dilated eye exam to diagnose floaters. The exam can spot problems like retinal tears.

Most floaters are harmless, but you should see a doctor if you have any of the following symptoms:

There’s been a sudden rise in the number of occurrences.

There are moments of brightness.

You might see a dark cloud or shadow moving across your vision.

These signs could be a sign of a tear in the retina, which is a problem that needs to be treated quickly to prevent permanent vision loss.

In most cases, no treatment is needed as floaters tend to become less noticeable over time. However, if you’re experiencing significant vision issues, there are steps you can take.

Vitrectomy: This is a type of operation in which the clear gel that fills the eye is removed and replaced with a saltwater solution.

Laser therapy: This treatment uses lasers to break up the floaters, making them less noticeable. Both treatments carry risks, including infection and retinal damage, so they are typically reserved for severe cases.

If your floaters are mild, some lifestyle changes can help you manage them:

Eye exercises: If you move your eyes up and down, floaters might move out of your line of sight.

Diet and supplements: Consuming foods rich in omega-3 fatty acids, vitamin A, and zinc can help maintain eye health.

Try not to smoke: Smoking can make eye problems worse and reduce eye health.

Most people find floaters to be somewhat annoying, but they’re not considered harmful. However, if you stay informed and proactive, you can ensure your eyes remain healthy for years to come.

The best way to stop more serious eye problems is to have regular check-ups and know the signs of eye disease.
