Sep 1, 2025 | Dry Eye, Eye Health Info

Itchy, watery eyes can be frustrating, especially when you’re not sure what’s causing the discomfort. Is it allergies? Is it dry eye syndrome?  

Although the symptoms often overlap, finding the right treatment starts with knowing what’s causing the issue. If your symptoms don’t improve, our experienced team offers effective eye allergy and dry eye treatment in Decatur to help you feel better. Keep reading to learn how you can tell whether it’s dry eye or allergies. 

Common symptoms of dry eye 

Dry eye happens when your eyes don’t produce enough tears or when your tears evaporate too quickly. This condition often causes: 

  • A gritty or sandy feeling in the eyes 
  • Stinging or burning sensations 
  • Blurred vision that may improve with blinking 
  • Eye fatigue 
  • Discomfort after screen time 
  • Light sensitivity 

Dry eye is typically chronic and may worsen throughout the day, especially in dry or windy environments. 

Common symptoms of eye allergies 

Eye allergies, or allergic conjunctivitis, are caused by exposure to allergens like pollen, dust, or pet dander. Symptoms often include: 

  • Itchy eyes 
  • Redness 
  • Watery discharge 
  • Puffy or swollen eyelids 
  • Sneezing or nasal congestion (often paired with eye symptoms) 

Allergy-related symptoms tend to come on quickly, often after exposure to a specific trigger, and may improve with antihistamines. 

Dry eyes vs. allergies: Key differences to look for 

While dry eye and allergies can both cause redness and watering, there are a few clues to help you tell them apart: 

  • Itchiness is more intense and frequent with allergies 
  • Grittiness or burning usually indicates dry eye 
  • Allergy symptoms often include nasal issues 
  • Dry eye symptoms worsen in dry indoor environments 
  • Seasonal changes often trigger allergies, while dry eye can persist year-round 

Can seasonal allergies cause dry eyes? 

Yes, seasonal allergies can contribute to dry eye symptoms. Allergic reactions can disrupt the tear film, causing inflammation and making it harder for your eyes to stay properly lubricated.  

If you have both allergies and dry eye, your eyes may feel even more irritated during allergy season. Treating one without addressing the other may not fully relieve your discomfort. 

Finding relief for your symptoms 

The right treatment depends on the root cause of your symptoms. Artificial tears can offer temporary relief, but chronic dry eye may require a customized approach.  

If you suspect dry eye is behind your irritation, a comprehensive eye exam can help confirm the diagnosis and determine the best dry eye treatment for your needs. To schedule an appointment at Decatur Family Eye Care, please give us a call today or use our online appointment request form.
