"Allergy eyedrops are liquid medicines used to treat symptoms of eye allergies. Eye allergy symptoms include:

A burning feeling in your eye
Feeling like something is in the eye
Itchy eyes
Red (bloodshot) eyes
Swollen eyelid
Tearing
An eye allergy can be triggered by the same things that cause hay fever, such as:
Pollen
Dust
Pet dander
Certain medications or contact lenses can also be triggers.
Types of Allergy Eyedrops
Your doctor may first suggest you take these steps:
Use artificial tears.
Place a cold cloth on the eyes.
Avoid your allergy triggers.
Which type of allergy eyedrop you use depends on:
The cause of your allergy
Your symptoms
How much the symptoms affect your daily activities

There are many types of allergy eyedrops. Not all treat all allergy symptoms. For example, one that relieves red eyes may not stop the itching.
Some are sold over the counter. For others you need a prescription from a doctor. Some relieve symptoms quickly. Others provide long-term relief.
