Why Do I Have Dry Eye in One Eye Only?

Sep 1, 2025

While dry eye usually affects both eyes, sometimes one eye may be more irritated than the other. If you’re searching for relief, dry eye treatment in Plaquemine and Baton Rouge could be the solution you need.  

In this blog, we’ll explore why dry eye might affect one eye only, possible causes, and how different treatment options can provide much-needed relief. 

Common causes of dry eye in one eye 

Blocked oil glands 

The glands along your eyelids produce oils that keep tears from evaporating too quickly. If these glands become blocked in one eye, that eye may feel drier than the other. At Southern Eye Centers, we offer treatment options like LidPro or MiBo Thermoflo to help restore healthy oil flow and improve tear quality. 

Eye injuries or surgery 

An eye injury, even a minor scratch, can affect tear production or distribution. Surgery on one eye, such as cataract or LASIK surgery, can also temporarily trigger dryness. 

Contact lens use 

If you wear contact lenses, one eye may be more affected if a lens doesn’t fit properly or if you wear it longer than recommended. 

Underlying medical conditions 

Certain conditions, like autoimmune diseases, Bell’s palsy, or eyelid inflammation, may affect one eye more than the other, leading to uneven symptoms. 

Environmental factors 

Exposure to wind, fans, air conditioning, or heating vents directed toward one eye can cause that eye to dry out faster than the other. Even sitting near a desk fan or sleeping with a window open can create uneven dryness. 

Can dry eyes cause blurry vision in one eye? 

Yes, dry eyes can sometimes cause blurry vision in just one eye. When the tear film doesn’t spread evenly across the eye’s surface, vision can fluctuate and become hazy. If one eye is producing fewer tears, or if its oil glands are more blocked, the vision for that eye may appear blurrier than the other. 

Blurry vision from dry eye often improves after blinking or using artificial tears. However, if it persists, it may indicate an underlying issue that needs professional care. A comprehensive eye exam can help determine whether the blurriness is from dry eye disease or another eye condition. 

How an eye doctor can help 

Scheduling an eye exam is essential for understanding why you’re experiencing dry eye in just one eye. During the exam, our experienced eye doctor can pinpoint whether your symptoms are due to blocked glands, contact lens issues, inflammation, or another cause. 

They may recommend advanced treatments, such as: 

  • OptiLight IPL therapy: Targets inflammation that contributes to dry eye disease. 
  • MiBo Thermoflo: Uses heat and gentle massage to unclog blocked glands. 
  • LidPro: A device designed to clean the eyelids and reduce buildup. 
  • Scleral lenses: Specialized contact lenses that vault over the cornea, creating a protective reservoir of moisture for severe dry eye. 

Finding lasting relief 

Even if your dry eye only affects one eye, it’s important to address the issue before it worsens. Effective treatment not only relieves discomfort but also helps protect your vision and eye health. With personalized care and advanced options available, you can find lasting comfort and keep your eyes feeling their best.
