Ocular (eye) allergies often affect the conjunctiva, a clear layer of skin overlying the eyes. This clear layer of skin is the same type of skin that lines the inside surface of the nose. Because these two areas are so similar, the same allergens (substances that induce an allergic reaction) can trigger the same allergic response in both areas.

Common allergens include:

• Pollen
• 
  
• Grass
• 
  
• Weeds
• 
  
• Dust
• 
  
• Pet dander

The main difference between SAC and PAC is the timing of the symptoms.

• If you have SAC, you generally have problems for a short period of time.
  
  
  • You may be bothered in the spring by tree pollen, in the summer by grass pollen, or in the fall by weed pollen.
  • 
    
  • Generally, your symptoms resolve during other times of the year, especially in the winter.
• 
  
• If you have PAC, your problems probably last throughout the year.
  
  
  • Instead of outdoor allergens, you have problems with indoor allergens, such as dust mites, cockroaches, and pet dander.
  • 
    
  • Seasonal outdoor allergens may worsen your problems if you are sensitive to them as well.
