Eye floaters are a common visual occurrence that nearly everyone experiences at some point. They often look like small dots, cobwebs, or thread-like shapes drifting across your vision, especially when you look at a bright surface like a blue sky or a white wall. For most people, floaters are harmless, but sometimes they can signal a more serious eye condition that requires prompt care. In most cases, floaters are a normal part of aging, but regular eye exams help ensure your retina remains healthy.
At Everett & Hurite Eyecare Specialists, we provide expert diagnosis and treatment for floaters and flashes across Pittsburgh, Butler, Greensburg, Cranberry, Monroeville, and surrounding areas. Our board-certified ophthalmologists and retina specialists use advanced technology to detect the cause of visual disturbances and help patients protect their sight.
In this article, we’ll cover five key things every Pittsburgh resident should know about eye floaters, from their causes to when it’s time to see an eye doctor.
1. Understanding What Eye Floaters Are and How They Form
Eye floaters are tiny, shadow-like shapes that appear to move within your field of vision. Despite seeming to float in front of your eyes, they actually form inside the vitreous humor, the clear, gel-like substance that fills the space between your lens and retina.
As we age, this vitreous gel begins to shrink and liquefy, creating microscopic fibers that clump together. These clumps cast shadows on the retina, the light-sensitive tissue at the back of the eye, producing the illusion of floating particles.
The eye floaters' meaning is simple: they’re a visual result of natural changes inside the eye. Most are normal and a part of aging, but not all should be ignored.
2. The Common Causes of Floaters
While aging is the leading cause of floaters, several other conditions can trigger or worsen them. Understanding these causes helps patients recognize when to seek medical care.
While aging is the leading cause of floaters, several other conditions can trigger or worsen them. Understanding these causes helps patients recognize when to seek medical care.
Natural Aging and Posterior Vitreous Detachment (PVD)
The most common cause of floaters is posterior vitreous detachment (PVD), a normal, age-related process where the vitreous gel pulls away from the retina. This typically occurs in people over age 50 and is a major reason for new floaters.
Nearsightedness (Myopia)
Individuals who are nearsighted tend to develop floaters earlier in life due to changes in the structure of the eye.
Eye Surgery or Trauma
Cataract surgery, eye injuries, or previous inflammation can increase the likelihood of developing floaters.
Underlying Eye Diseases
Conditions such as diabetic retinopathy, uveitis (eye inflammation), or retinal tears and detachments can cause sudden or excessive floaters.
Floaters related to disease or injury often appear suddenly or are accompanied by other symptoms like flashes of light, vision loss, or dark shadows, all warning signs that need immediate medical attention.
3. When Floaters Are Normal, And When They May Signal a Problem
It’s important to understand that floaters are not always dangerous. Most are benign and fade with time as the brain adapts. However, knowing when they might signal a problem can protect you from serious eye damage.
Normal Floaters
- Appear gradually over time
- Move when you move your eyes
- Don’t obstruct central vision
- Remain stable in number and shape
Warning Signs of a Serious Issue
- A sudden shower of new floaters
- Flashes of light in peripheral vision
- Blurred or distorted vision
- Loss of side vision or a curtain-like shadow
These symptoms can indicate a retinal tear or detachment, both of which are medical emergencies that require immediate attention from an eye specialist.
At Everett & Hurite, our ophthalmologists are experienced in diagnosing retinal problems early using comprehensive eye exams and imaging tests such as optical coherence tomography (OCT) and ultrasound imaging.
4. How Eye Floaters Affect Vision and Daily Life
Even when benign, floaters can still affect your visual clarity and quality of life. Many patients report feeling distracted while reading, driving, or working on computers, especially when floaters drift across their central vision.
Over time, the brain usually learns to ignore them. But for some, especially those with large or numerous floaters, they can interfere with everyday activities and cause frustration.
If floaters significantly disrupt your vision, Everett & Hurite offers advanced eye floaters treatment options to help.
Observation and Monitoring
For most people, floaters don’t require treatment. Regular monitoring ensures no retinal damage develops.
Therapies and Procedures
Therapies such as laser can lead to retinal detachment and are not recommended. In rare cases where floaters severely impact vision, a vitrectomy may be recommended. This procedure involves removing the vitreous gel and replacing it with a clear solution. It can significantly improve visual clarity but is generally reserved for severe cases due to surgical risks.
Your ophthalmologist will discuss which treatment, if any, best suits your vision needs.
5. Why Regular Eye Exams Are Essential for Monitoring Floaters
Even when your floaters seem minor, scheduling routine eye exams is crucial for protecting your vision. Many serious eye conditions, including retinal tears, diabetic retinopathy, and macular degeneration, may develop without noticeable early symptoms.
At Everett & Hurite, our comprehensive eye exams help:
- Detect retinal changes before they cause vision loss
- Monitor the progression of age-related vitreous changes
- Identify new floaters or flashes early
- Provide peace of mind for patients concerned about their vision
Our specialists recommend annual eye exams for most adults, and more frequent visits for individuals with diabetes, high myopia, or a history of eye surgery.

Frequently Asked Questions
What are eye floaters?
Eye floaters are small specks or cobweb-like shapes that appear to drift across your vision, caused by clumps in the vitreous gel inside the eye.
What causes floaters to suddenly appear?
They often occur due to vitreous changes from aging, but sudden-onset floaters can signal retinal tears, inflammation, or bleeding.
Are floaters and flashes related?
Yes. Flashes happen when the vitreous tugs on the retina, often during the same process that causes floaters.
Do floaters go away on their own?
Many fade or become less noticeable over time. Persistent or large floaters can be treated with laser therapy or vitrectomy.
When should I see an eye doctor about floaters?
Seek immediate care if you notice a sudden increase in floaters, flashes of light, or a dark curtain over your vision.
