What Are Eye Floaters? Symptoms, Causes, and More
Floaters often drift in your field of vision. They may appear to follow your vision as your eyes move. They float away when you try to look directly at them.
Read on to find out more about the symptoms and causes of eye floaters. This article also discusses treatments, when to contact a doctor, and more.
Eye floaters are small shapes that drift into your field of vision. You may notice that they are more visible when you look at the sky or some other bright light.
The floaters can look like:
- tiny dots
- little bubbles
- threads or strings
You will find that the floaters move as you move your eye. Because of this, they are difficult to look at directly.
What are floaters and flashes?
Alongside eye floaters, you may experience flashes of light. Neither symptom is usually a cause for concern. However, because they may occur due to retinal detachment, it’s important to contact your eye doctor for advice.
The clumps of degenerated collagen that form floaters drift can in and out of your field of vision. As they move within your eye, they cast a shadow on your retina. The retina is a layer of tissue at the back of your eye that processes light. When you see a floater, you are actually seeing its shadow, not the floater itself.
In addition to age, eye floaters can also result from other eye conditions. Possible causes include:
- bleeding in the eye
- retinal tear
- retinal detachment
- vitreous detachment
- uveitis, or inflammation of the uvea, which is the middle tissue layer of the eyeball wall
However, if eye floaters result from an eye condition or injury, treatment may be necessary. The type of treatment will depend on the underlying cause. Your doctor can provide more information about what treatments they recommend for your individual condition.
Your doctor may also recommend vitrectomy surgery. This involves removing some or all of the vitreous. If your doctor recommends a vitrectomy, they can explain more about the procedure.
Contact your doctor if you have concerns about eye floaters. While they can occur naturally with age, an accurate diagnosis can rule out other, more serious causes.
Additionally, contact your doctor if you experience:
- persistent flashes of light in your peripheral vision
- sudden deterioration of vision
- darkness covering part of your vision or at the sides of your vision
- sudden appearance of floaters
- sudden increase in the number of floaters
They may then carry out a dilated eye exam. This involves using eye drops to dilate your pupils. After this, they use an indirect ophthalmoscope device to examine the back of your eyes.
Usually, you won’t feel any pain during the dilated eye exam. However, you may feel some discomfort as your doctor examines your eyes up close.
You are more likely to develop eye floaters if you:
- have nearsighted vision
- have diabetes
- have had cataract surgery
- are over the age of 50 years, as there is an increased risk of vitreous detachment
Contact your doctor if you have concerns about the risks of eye floaters or vitreous detachment.
As eye floaters can occur as a natural part of aging, it may not be possible to prevent them.
However, you may be able to take steps to reduce their visibility. As floaters are more visible when looking at something bright, it may help to wear sunglasses when outdoors. Additionally, you can use a display to filter the brightness of a phones or computer screens .
