Can dry eye syndrome cause floaters​?
Dry eye syndrome does not cause floaters. Floaters originate from changes in the eye’s internal vitreous gel, not from the surface where dry eye occurs. However, dry eye can make existing floaters more noticeable due to blurred or fluctuating vision.
What Are Floaters, and What Causes Them?
Floaters are small specks, threads, or cobweb-like shapes that “float” or drift across your field of vision. They are caused by small clumps or strands of collagen forming in the vitreous humor—the gel-like substance filling the inside of the eye. These clumps cast shadows on the retina, which appear as floaters.
The main causes of floaters include:
- Age-related changes as the vitreous shrinks and liquefies
- Posterior vitreous detachment (when the vitreous pulls away from the retina)
- Eye trauma or injury
- Eye diseases such as uveitis (inflammation)
- Bleeding inside the eye
- Retinal tears or detachment
How Is Dry Eye Different from Floaters?
Dry eye syndrome is a condition where the eyes do not produce enough tears or the tears evaporate too quickly, leading to symptoms like discomfort, burning, grittiness, redness, and sometimes blurred vision. These symptoms are related to the eye's surface and tear film.
Floaters, in contrast, are an internal issue caused by changes in the vitreous gel, not by tear production or the eye’s surface. The two conditions are unrelated in their origin and mechanism.
Can Dry Eye Make Floaters More Noticeable?
While dry eye does not create floaters, it can make you more aware of them. Blurred or fluctuating vision from dry eye may draw your attention to preexisting floaters, making them seem more prominent. Eye strain and irritation from dryness can also increase sensitivity to visual disturbances.
When Should I See a Doctor for Floaters?
Most floaters are harmless and related to normal aging. However, seek urgent medical attention if you experience:
- A sudden increase in floaters
- Flashes of light
- A dark curtain or shadow over your vision
- Sudden loss of vision or eye pain
These symptoms could indicate a retinal tear or detachment, which requires immediate treatment to prevent permanent vision loss.

How Are Dry Eye and Floaters Treated?
For individuals experiencing the discomfort of dry eyes or the distraction of eye floaters, a range of treatments are available, from simple home remedies to advanced medical procedures.
Dry eye treatments:
- Over-the-counter lubricating eye drops (artificial tears)
- Prescription drops like cyclosporine (Restasis), lifitegrast (Xiidra), or anti-inflammatory medications
- Lifestyle adjustments: taking screen breaks, using humidifiers, warm compresses, and eyelid hygiene
- Procedures for severe cases: punctal plugs, thermal cautery, scleral lenses, or light therapy
Floaters:
- Usually, no treatment is needed; observation is recommended
- In rare, severe cases, a vitrectomy (surgical removal of the vitreous gel) or laser therapy may be considered, but these carry risks and are reserved for significant visual impairment
- No medications are available to dissolve or prevent floaters
Key Takeaway
Dry eye syndrome does not cause floaters, but both conditions can occur together, especially with age. While dry eye may make existing floaters more noticeable, it does not create them. Treat dry eye symptoms to improve comfort, and monitor any sudden changes in floaters—seek prompt medical care if you notice warning signs of a retinal problem.

Can dry eyes cause blurry vision? Which medications help?
Yes, dry eyes can cause blurry or fluctuating vision. This occurs because dry eye syndrome disrupts the tear film that coats the eye’s surface, leading to uneven light refraction and irregularities on the corneal surface. Meibomian gland dysfunction, which affects the oily layer of the tear film, is a major contributor to this problem.
