Yes, allergies can cause blurry vision! When pollen, dust mites or pet dander gets in your body, it can trigger an immune response that leads to inflammation and irritation in your eyes. This irritation can cause blurry vision and more.
As you can see, the main symptoms of eye allergies are obvious: redness, itchiness, watery eyes, and blurry vision
For this reason, I am here to explain how allergies affect your vision, symptoms, treatment and prevention.
Can Allergies Cause Blurry Vision?
Yes, allergies can cause blurry vision, and you might notice it more when your symptoms flare up. When your body overreacts to common irritants like pollen or dust mites it releases histamines and other chemicals that cause inflammation. So you might experience itchiness, redness and excessive tearing all of which can cloud your vision.
The discharge that accumulates from allergens is the main cause of blurry vision during an allergic reaction.
Generally speaking, this film like layer can create a haze over your line of sight. Allergies can also increase light sensitivity so it’s uncomfortable for contact lens wearers.
During peak allergy seasons when your vision is compromised, artificial tears can be a lifesaver.
They help flush out irritants from the ocular surface and soothe dryness induced irritation, provide much needed moisture. If you notice fuzzy sight during pollen surges it’s probably due to your body’s hypersensitivity response.
Common Eye Allergy Symptoms
Allergic conjunctivitis or eye allergies occurs when allergens trigger an immune response in your eyes and causes inflammation and irritation.
This can disrupt your daily activities from mild annoyances to severe vision related challenges. Here are the signs that you might be experiencing eye allergy symptoms:
- Redness
- Itchiness
- Excessive tearing or watery eyes
- Blurry vision
These symptoms are caused by histamines released during your body’s defense against allergens and causes swelling and inflammation in the eye tissues. So tasks that require clear vision like driving or reading fine print can be severely impacted.
If you’re experiencing persistent symptoms like itchiness, redness around the eyes or any changes in your vision see a doctor.
Seasonal vs Perennial Allergic Conjunctivitis
Eye allergies can be caused by many things and can occur in different patterns. Seasonal allergic conjunctivitis is caused by pollen from trees, grasses and weeds that bloom during specific times of the year.
Often accompanied by hay fever symptoms it brings discomfort like redness, itchiness and watering especially in spring and autumn the worst seasons for those with seasonal eye allergies.
On the other hand perennial allergic conjunctivitis is year round due to exposure to indoor allergens like dust mites or pet dander.
Unlike its seasonal counterpart which fluctuates with plant pollination cycles this one is constant and causes ongoing irritation from common household irritants.
Contact Lens Allergies
For contact lens wearers eye allergies especially allergic conjunctivitis adds another layer of complexity.
One type of this allergy is giant papillary conjunctivitis which occurs in contact lens users and involves the formation of small bumps on the inner eyelid surface. This condition can cause swelling, itchiness and discharge from the mucous membranes and makes wearing lenses uncomfortable and blurry vision.
Contact allergic conjunctivitis is caused by irritation from the contacts themselves or proteins in your tears. Symptoms are swelling, itchiness and mucous discharge making contact lens wear uncomfortable due to ongoing irritation and fuzzy vision.
When to See a Doctor
If you have blurry vision for more than a day or two, see an eye doctor. Symptoms like thick mucus that glues your eyelids together and blocks your vision are red flags that you need to see a doctor.
Also if you feel like there’s something in your eye or notice more mucus around your eyes, these are additional reasons to see an eye doctor. If over the counter solutions don’t work, seeing an allergist can be helpful. They can identify the allergen and create a personalized treatment plan.
