Eye Allergies
What are eye allergies?
An eye allergy is an allergic reaction to some substance on the
surface of the eye. With an eye allergy, your child will have:
- itchy eyes (your child may frequently rub them)
- increased tearing
- red or pink eyes (without pus)
- mild swelling of the eyelids.
What is the cause?
Eye allergies that occur during the same season each year are
caused by pollens. Pollens from trees, grasses, and weeds are
invisible and travel in the air. Allergies that are not seasonal
may be caused by pets (for example, cats), feathers, perfumes, eye
makeup, or another substance. The things that cause allergies are
called allergens.
How long does it last?
Most eye allergies caused by a pollen last 4 to 6 weeks, which is
the length of most pollen seasons. If the allergic substance can
be identified (for example, a cat) AND avoided, the symptoms will
not return .
How can I take care of my child?
- Remove pollen
First wash the pollen off the face. Then use a clean washcloth
and cool water to clean off the eyelids. (Tears will wash the
pollen out of the eyes.) This rinse of the eyelids may need to
be repeated every time your child comes in on a windy day.
Pollen also collects in the hair and on exposed body surfaces.
This pollen can easily be reintroduced into the eyes.
Therefore, give your child a shower and shampoo every night
before bedtime. Encourage your child not to touch his eyes
unless his hands have been washed recently.
- Antihistamine/Vasoconstrictor Eyedrops
Usually, the eyes will feel much better after the pollen is
washed out and a cold compress (for example, a cold washcloth)
is applied. If they are still itchy or bloodshot, your child
may need special eyedrops prescribed by your healthcare
provider. Antihistamine eyedrops that you can buy without a
prescription are sometimes helpful.
- Oral antihistamines
If these measures aren't effective, your child probably also
has hay fever (that is, allergic symptoms of the nose) and
your child needs an oral antihistamine. The following
antihistamines are OTC: Benadryl and chlorpheniramine products
work for 8 hours. Zyrtec and Claritin products work for 24
hours. Give the correct dosage as listed on the product. They
need to be taken on a daily basis until pollen season is over.
This will control both the nose and eye symptoms.
How can eye allergies be prevented?
Some suggestions to reduce exposure to allergens are:
- Keep your child's bedroom windows shut and use central air
conditioning during spring, summer, and fall pollen seasons.
If a room air conditioner is used, recirculate the indoor air
rather than pulling outside air indoors. Air purifiers can be
helpful if filters are kept clean. HEPA (high efficiency
particulate air) filters are best. Wash or change air filters
once a month.
- Your child should shower, shampoo, and change clothes right
after working or playing outside during allergy season.
- Your child should not be outdoors when the lawn is being
mowed.
- Your child should wash his hands immediately after any contact
with a pet.
When should I call my child's healthcare provider?
Call during office hours if:
- This treatment and an antihistamine do not relieve most of the
symptoms in 2 or 3 days.
- You have other concerns or questions.
