Eye Floaters and Flashes: When to See a Doctor

Eye floaters and flashes are often harmless, but sometimes they signal a serious problem. Floaters are tiny shapes or streaks that drift across your vision.

Flashes are sudden bursts of light. If you see a sudden shower of new floaters, flashes that keep coming, or a dark curtain over your sight, get care right away.

If you are 55 or older and live in The Villages, Florida, this guide explains the causes, the warning signs and what to expect at an exam.

What Are Eye Floaters and Flashes?

Eye floaters. Floaters look like small spots, squiggly lines or cobwebs.

You see them most against a bright background, like a blue sky. They form when tiny clumps or strands appear in the vitreous.

That is the clear, gel-like fluid that fills your eye. The clumps cast shadows on your retina, and you see them as floaters.

Eye flashes. Flashes look like streaks or bursts of light. They can happen when the vitreous gel pulls on the retina, which then fires its nerve cells.

Flashes can come with normal aging. However, they can also signal a retinal tear or detachment.

Common Causes of Eye Floaters and Flashes

These are the most common reasons people notice eye floaters and flashes.

Aging. With age, the vitreous gel starts to liquefy and pull away from the retina.

This often begins after age 50. It is called posterior vitreous detachment (PVD), and it is a leading cause of floaters and flashes.

Eye injuries. A blow to the head or eye can disturb the vitreous or tear the retina. If you golf, cycle or play active sports, take care to avoid eye injuries.

Other eye conditions. These include:

• Retinal tear or detachment: This is serious and needs care right away. The retina pulls away from its normal place.
• Cataracts: They are not directly related, but they can cause vision changes that some people mistake for floaters. See cataracts or our page on cataract symptoms.
• Other diseases: Conditions like glaucoma or diabetic retinopathy can also affect your vision. Find details about glaucoma or read about diabetic eye disease.

When to Worry About Eye Floaters and Flashes

Occasional floaters and flashes are common and usually harmless. Get medical care at once if you notice any of these:

• A sudden increase in floaters, like a shower of spots
• Bright flashes of light that last or keep coming back
• A dark curtain or shadow moving across your vision
• Loss of side vision
• Blurred or distorted central vision

These can be signs of a retinal tear or detachment. Both need urgent treatment to prevent permanent vision loss.

If you have these symptoms, call an eye care provider right away. Ask our clinic about a same-day retinal exam.

What to Expect at the Exam

At Hindsight Eye Care, a complete eye exam for floaters and flashes has three parts.

1. Symptom review: We ask about your floaters, flashes and any other vision changes.

2. Dilated eye exam: Drops widen your pupils. Then we can look closely at your retina and vitreous for problems. See dilated eye exams.

3. Imaging tests: If needed, we may use retinal imaging to find small changes that routine exams can miss.

Tips to Protect Your Eye Health

These steps keep your eyes healthy as you age.

• Wear sunglasses. Florida sun can harm your eyes over time. Choose sunglasses with 100% UV protection.
• Stay hydrated. Enough water helps with dry eye symptoms.
• Take screen breaks. If you use tablets and e-readers, rest your eyes often.
• Get regular eye exams. Routine checkups catch problems early. Go once a year, even if you feel fine.
• Stay active and eat well. A diet rich in omega-3 fats, antioxidants and leafy greens supports eye health. Activity also helps manage conditions like diabetes, which can harm your eyes.

Act Quickly When Something Changes

Some eye conditions grow slowly. Others, like a retinal tear, can get worse fast, and prompt treatment can save your vision.
