Can dry eyes cause blurry vision? Which medications help?

Medically reviewed by Kristianne Hannemann, PharmD. Last updated on May 30, 2025.

Official Answer by Drugs.com

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.

Why Do Dry Eyes Cause Blurry Vision?

Dry eyes can cause blurry vision primarily because a healthy and stable tear film is essential for clear eyesight. The tear film is a complex, multi-layered coating on the surface of your eye that plays an important role in how light is focused.

Common Symptoms of Dry Eye

Common symptoms of dry eye include:

Which Medications Help Blurry Vision from Dry Eyes?

Several types of medications can help improve blurry vision by addressing the underlying causes of dryness and an unstable tear film. The primary goal of these medications is to restore a healthy tear film.

Over-the-Counter (OTC) Options

Prescription Eye Drops

Prescription Nasal Spray

How Long Does It Take for Medications to Work?

The time it takes for dry eye medications to work can vary significantly depending on the type of medication, the severity of your dry eye condition, and individual factors.

Are There Non-Drug Treatments for Dry Eye and Blurry Vision?

Yes, there are many effective non-drug treatments for dry eye and the associated blurry vision. These approaches focus on alleviating symptoms, improving tear quality and quantity.

When Should I See an Eye Doctor?

Prompt evaluation by an eye care professional is important to prevent long-term damage and to tailor a treatment plan that addresses the underlying cause of your dry eye and blurry vision. Consult an eye professional if:

It's important to consult with an eye doctor (ophthalmologist or optometrist) to determine the underlying cause of your dry eye and blurry vision. They can recommend the most appropriate non-drug treatments based on your specific condition. Often, a combination of these approaches is most effective.

What is the difference between Cequa and Restasis?

Both Cequa and Restasis are eye drops that contain cyclosporine. They are used to increase tear production in patients with dry eye disease (medically called keratoconjunctivitis sicca). However, Cequa incorporates a novel nanomicellar technology of cyclosporine A to allow delivery of high concentrations of the medication into the eye. Restasis is not manufactured using nanomicellar technology. Nanomicellar technology can help deliver poorly water-soluble drugs into the eye and protect the drug molecule. Continue reading
