Symptoms
The primary types of eye allergy are seasonal or perennial allergic conjunctivitis, vernal keratoconjunctivitis, atopic keratoconjunctivitis, contact allergic conjunctivitis and giant papillary conjunctivitis.

Seasonal and perennial allergic conjunctivitis
Seasonal allergic conjunctivitis (SAC) is by far the most common type of eye allergy. Patients experience symptoms in spring, summer or fall, depending on the type of plant pollens in the air. Typical symptoms include:

Itching
Redness
Burning
Clear, watery discharge
People with SAC may have chronic dark circles (known as allergic shiners) under their eyes. The eyelids may be puffy, and bright lights may be bothersome. SAC symptoms often accompany the runny nose, sneezing and nasal congestion associated with hay fever and other seasonal allergies. The itching may be so bothersome that patients rub their eyes frequently, making symptoms worse and potentially causing infection.

Perennial wellbutrin 300mg usa allergic conjunctivitis (PAC), as its name implies, occurs year-round. Symptoms are the same as with SAC, but tend to be milder. They are caused by reactions to dust mites, mold, pet dander or other household allergens, rather than pollen.

Vernal keratoconjunctivitis is a more serious eye allergy than SAC or PAC. While it can occur year-round, symptoms may worsen seasonally. It primarily occurs in boys and young men; about 75 percent of patients also have eczema or asthma. Symptoms include:

Itching
Significant tearing and production of thick mucus
The feeling of having something in the eye (foreign body sensation)
Aversion to light (photophobia)
If left untreated, vernal keratoconjunctivitis can impair vision.

Atopic keratoconjunctivitis
This type of allergy primarily affects older patients – mostly men with a history of allergic dermatitis. Symptoms of atopic keratoconjunctivitis can occur year-round and are similar to those of vernal keratoconjunctivitis:

Severe itching
Burning
Redness
Significant production of thick mucus that, after sleep, may cause the eyelids to stick together
