Have you ever noticed tiny spots, squiggly lines, or cobweb-like shapes drifting across your field of vision? These are commonly known as eye floaters, and they are a frequent reason people schedule an appointment with an eye care professional.
In many cases, eye floaters are a normal part of aging and are harmless. However, a sudden increase in floaters or the appearance of other vision changes can sometimes signal a more serious eye condition that requires immediate medical attention.
Here’s what you should know about eye floaters, what causes them, and when it’s time to seek professional care.
What Are Eye Floaters?
Eye floaters are small clumps or strands within the gel-like substance called the vitreous, which fills the inside of your eye. As light enters the eye, these tiny particles cast shadows on the retina, causing you to see floating shapes that seem to drift as your eyes move.
Floaters may appear as:
Small black or gray dots
Thread-like strands
Cobweb patterns
Transparent rings
Tiny specks that move across your vision
They are often easier to notice when looking at a bright background, such as a clear blue sky or a white wall.
What Causes Eye Floaters?
The most common cause of eye floaters is the natural aging process.
As we age, the vitreous gradually becomes more liquid and may shrink slightly. This causes tiny fibers inside the gel to clump together, creating the shadows we recognize as floaters.
Other possible causes include:
Nearsightedness (myopia)
Previous eye surgery
Eye inflammation
Eye injuries
Diabetic eye disease
Bleeding inside the eye
Most floaters related to aging are not dangerous.
Are Eye Floaters Normal?
For many adults, especially after age 50, occasional floaters are considered a normal part of aging.
Many people notice that:
Floaters become less noticeable over time.
The brain gradually learns to ignore them.
They rarely interfere with daily activities.
However, any sudden or dramatic change should always be evaluated promptly.
