Contact Lens Safety Tips for Allergy Sufferers: Minimizing Discomfort and Irritation
As an optometrist with years of experience, I've seen firsthand how seasonal allergies can absolutely disrupt contact lens wear. It’s a common issue, especially here in Okotoks and throughout Alberta with our distinct seasons and prairie pollen counts. This isn’t just about a little discomfort; it’s about maintaining eye health and avoiding complications. Many patients don’t realize allergies impact contact lens wear so significantly – it’s not just itchy eyes, but changes in tear film, lens deposit buildup, and increased risk of infection. This post will go beyond basic advice and give you the detailed information you need to manage contact lenses during allergy season.
Why are Allergies Worse for Contact Lens Wearers?
Allergies cause your eyes to react to airborne allergens like pollen, dust, and pet dander. This reaction leads to inflammation and increased histamine production, resulting in itching, redness, and watering. Sounds simple enough, right? But for contact lens wearers, it's more complex. Here’s what most people don't realize:
- Tear Film Disruption: A healthy tear film is crucial for comfortable lens wear. Allergies disrupt this film, making lenses feel dry and irritating. The lens then absorbs more allergens, creating a vicious cycle.
- Increased Deposit Buildup: Inflamed eyes produce more mucus. This mucus, combined with allergens, adheres to the lens surface, creating deposits. These deposits can cause discomfort, blurred vision, and even corneal abrasion.
- Altered Lens Protein Binding: Allergens can actually change the way proteins bind to your lenses – even daily disposables aren’t immune. This makes lenses less comfortable and harder to clean effectively.
- Corneal Sensitivity: Prolonged allergy symptoms can temporarily increase corneal sensitivity, making lens wear even more uncomfortable.
What Type of Contact Lenses are Best During Allergy Season?
The "best" lens depends on the severity of your allergies and your lifestyle. Here's a breakdown:
- Daily Disposables: These are almost always my first recommendation for allergy sufferers. They minimize deposit buildup because you wear a fresh, clean lens every day. While they are typically the most expensive option per year (roughly $600 - $1200 CAD depending on brand and prescription), the reduced risk of complications and increased comfort often outweigh the cost.
- Silicone Hydrogel Lenses: Whether daily or monthly, silicone hydrogel materials allow more oxygen to reach the cornea, which can help soothe irritated eyes. They are generally more comfortable for extended wear, but still require diligent cleaning if they aren't daily disposables. Expect to pay around $30 - $60 CAD for a monthly supply of silicone hydrogel lenses.
- Traditional Hydrogel Lenses: These are the least expensive option (around $20 - $40 CAD per month), but also the most prone to deposit buildup and dryness. I generally advise against these for allergy sufferers unless budget is a significant constraint.
- Gas Permeable (GP) Lenses: While less common now, GP lenses are naturally resistant to deposit buildup and can be a good option for severe allergy sufferers. However, they require a longer adaptation period and can be more challenging to handle.
Important Note: Don’t switch lens types without consulting your optometrist. A proper fit is crucial, and different materials require different care routines.
Cleaning and Disinfecting: A Step-Up in Rigor
During allergy season, you need to be extremely diligent with lens cleaning. Here's what I tell my patients:
- Rub and Rinse, Even with "No-Rub" Solutions: Many modern solutions claim to be “no-rub,” but studies consistently show that manual rubbing, followed by rinsing, removes significantly more deposits. Spend at least 20-30 seconds gently rubbing each lens.
- Use a Multi-Purpose Solution Designed for Allergy Relief: Some solutions contain ingredients like hyaluronic acid or poloxamine, which can help soothe irritated eyes and bind moisture to the lens.
- Replace Your Lens Case Monthly: Lens cases harbor bacteria and allergens. Replace them every month, or even more frequently if you experience persistent problems.
- Never Use Tap Water: Tap water contains microorganisms that can cause serious eye infections, like Acanthamoeba keratitis. Always use fresh, sterile contact lens solution.
- Consider a Second Cleaning Step: For severe allergies, I sometimes recommend a enzymatic cleaner to remove stubborn protein deposits, used in addition to your daily routine.
What About Eye Drops? A Guide to Relief
Eye drops can provide temporary relief, but choosing the right ones is key:
- Artificial Tears: These are a safe, first-line treatment for dry, irritated eyes. Choose preservative-free options if you use them frequently (more than 4 times a day).
- Antihistamine Eye Drops: These can directly combat allergy symptoms, but can also cause dryness. Use them cautiously and follow your optometrist’s instructions.
- Mast Cell Stabilizer Eye Drops: These work by preventing the release of histamine. They take several days to start working, but provide longer-lasting relief.
- Avoid Redness Relieving Drops (with vasoconstrictors): These drops may temporarily reduce redness, but they can also constrict blood vessels and worsen dryness in the long run.
Crucially: Remove your contact lenses before applying any eye drops, unless the drops are specifically designed for use with lenses.
When Should I Switch to Glasses?
There’s no shame in taking a break from contact lenses! Here are some situations where switching to glasses is the best course of action:
- Severe Symptoms: If your allergy symptoms are severe and not responding to treatment, it’s time to give your eyes a rest.
- Persistent Redness or Pain: Any persistent redness, pain, or blurred vision should be evaluated by an optometrist immediately.
- Lens Intolerance: If you find that you can't comfortably wear your lenses for even a short period, switch to glasses.
- High Pollen Counts: On days with extremely high pollen counts (check local weather reports!), consider wearing glasses to minimize exposure.
Often, patients in the Calgary region find that a pair of prescription sunglasses is a lifesaver during peak pollen times – protecting their eyes and providing clear vision.
Red Flags: When to See an Optometrist Immediately
Don’t ignore these symptoms:
- Severe eye pain
- Significant vision loss
- Excessive discharge
- Extreme redness
- Sensitivity to light
These could indicate a corneal infection or other serious problem that requires immediate attention.
Remember, managing contact lens wear with allergies requires a proactive approach. It's about understanding why these issues happen and taking the necessary steps to protect your eye health. Don't hesitate to discuss your concerns with your optometrist – we’re here to help you see clearly and comfortably, even during allergy season.
