Can Dry Eyes Cause Floaters?


When eye floaters are sneaking into your sight, you might be wondering if your dry eyes are the cause. Dry eyes can cause various symptoms, and many can impact your vision. Visiting Eye Rx for an eye exam or dry eye therapy can diagnose your eye health and help you understand your symptoms.

But are floaters a symptom of dry eyes? Read on to learn more about what causes floaters.


A floater is a shape that appears in your vision, usually looking like a dark spot, squiggly line, string, or even cobwebs. It may seem like an object has suddenly appeared in front of your eye, but the problem is inside.

After eye movement, the floater moves inside your eye, drifting across your visions. You may try, but you can’t focus on it.

The floater, a small cluster of cells, seems to float because it’s suspended in the vitreous layer of your eye. You’re not seeing the floater but rather the shadow of the cell cluster as it moves across the retina.

The retina is responsible for receiving light and changing it into electrical signals. The signals are sent to the brain through the optic nerve, and we perceive the signals as vision.

The vitreous layer is a gel-like layer. The layer is transparent, allowing light to travel through and reach the retina easily. However, vitreous is a substance containing proteins, which can form protein deposits trapped inside the ordinarily transparent fluid. Those protein deposits can get trapped if formed at birth or deteriorate because of aging.


Dry eyes can lead to additional symptoms and eye conditions, but dry eyes alone do not cause floaters. You may experience dry eyes and floaters simultaneously, but treating dry eyes won’t eliminate floaters.

Although dry eye symptoms don’t include floaters but can cause:

  • Dry eyes

  • Blurry vision

  • Redness

  • Light sensitivity

  • Watery eyes

  • Stringy mucus

  • Burning or scratchy sensation

Dry eyes and floaters can occur together or alongside other eye conditions, as they share common risk factors. There are two main reasons both eye effects can occur together: eye trauma or aging.


When our eyes are injured, it can impact our vision and eye health. However, depending on the injury, you may not notice symptoms, or symptoms may heal quickly.

Notably, some eye injuries can have lasting or delayed effects. For example, the outer layer may seem healed, but the inner eye may have sustained damage you can’t detect with the naked eye. Therefore, it’s crucial to visit an optometrist after an injury.

If you experience an eye injury or sudden vision symptoms, contact us immediately for an emergency eye care appointment.

After an eye trauma, your eyes may experience dryness, and sometimes symptoms occur later. The injury may have also caused cell movement within your vitreous, mainly if the damage caused vitreous detachment or retinal detachment.


Aging increases the risks of many eye conditions, including dry eyes, occurring in 30% of adults over 50.

Dry eyes may be caused by a natural decrease in quality tear production or as a result of medications. According to the CDC, nearly 70% of American adults 40–79 use one prescription medication, while almost 23% use at least 5 prescriptions.

Floaters are also more common with aging because the vitreous fluid can weaken and deteriorate. The deterioration increases the protein deposits we perceive as spots or floating objects.


Other potential causes of floaters include:

  • Eye diseases

  • Diabetic retinopathy

  • Eye tumors

  • Retina damage

  • Bleeding in your vitreous

  • Infections causing eye inflammation

  • Autoimmune conditions

Multiple autoimmune disorders can cause vision problems. Some lead to inflammation, affecting the vitreous or retina. Some immune disorders can also cause dry eyes, coinciding with floaters.


Floaters are permanent and won’t go away on their own. However, floaters are generally harmless, so most eye care professionals don’t treat them. Notably, the floating objects can become less noticeable over time, limiting their impact on vision.

When floaters increase or are linked to another eye condition, you may require treatment. After diagnosing your eye health and visual comfort, an optometrist may recommend options for treating floaters or causes related to floaters.


An ophthalmologist performs a vitrectomy to remove the vitreous humor from the eye. Then, an artificial fluid replaces the vitreous fluid to retain eye shape and function.

Although ophthalmologists can resolve floaters through a vitrectomy, the surgery is commonly used to treat other eye conditions, including:
