Key Takeaways
- Contact lenses can disrupt your tear film and reduce the flow of oxygen to your cornea, leading to dryness.
- Symptoms like stinging, blurred vision, and redness often get worse throughout the day.
- Lens type, fit, and hygiene habits all play a role in how comfortable your eyes feel.
- Silicone hydrogel and daily disposable lenses can help reduce dryness for many wearers.
- Persistent symptoms are worth discussing with an eye doctor for a personalized plan.
Why Your Eyes Feel Dry in Contacts
You put your contacts in, and everything feels fine. But by midday, your eyes are burning, tired, and uncomfortable. Sound familiar? Dry eye discomfort is one of the most common reasons why people struggle with contact lens wear.
Contact lenses can dry out your eyes because they sit directly on your tear film, reducing the amount of oxygen that reaches your cornea and reducing moisture levels in your eyes. The good news is that our team at Waterloo Vision Care Clinic understands what’s happening and can point you towards potential solutions. If you’re experiencing dryness, a dry eye consultation is a practical place to start.
Why Contacts and Dry Eyes Often Go Together
When your tear film, the thin layer of moisture covering your cornea, is healthy, your eyes remain comfortable and moist. Contacts can change that balance in a few important ways.
Because contacts rest directly on your eye, they absorb moisture from your tear film. They also limit how much oxygen reaches the surface of your cornea, while the friction from blinking against your lenses adds more irritation over time. These three factors set the stage for dryness.
Signs Your Contacts May Be Drying Out Your Eyes
Common Symptoms to Watch For
Dry eye caused by contacts doesn’t always feel the same for everyone. Some people notice a gritty or sandy feeling, like something is stuck in their eye. Others experience stinging or burning that makes it hard to focus.
You might also notice:
- Redness that doesn’t go away after a few blinks
- Blurred vision that clears up when you blink but comes back quickly
- Tired eyes earlier than usual in the day
- Watery eyes, which can actually be a sign that your eyes are overcompensating for dryness
- Sensitivity to light, especially indoors under fluorescent lighting
When Symptoms Get Worse
Pay attention to when your discomfort peaks. If your eyes feel fine in the morning but get progressively worse by evening, your tear film is likely wearing down as the day goes on.
Dry, air-conditioned offices, smoky spaces, and windy outdoor conditions can all make symptoms worse. These environments speed up tear evaporation, and with contacts already on your eyes, there’s less moisture available to compensate.
Factors That Make Dry Eyes Worse with Contacts
Wearing your lenses longer than recommended is one of the most common contributors to discomfort. Lenses accumulate protein deposits and debris over time, and the longer they sit in your eyes, the more irritating they become.
Fit matters more than most people realize. A lens that doesn’t match the shape of your eye can move around too much (or not at all), reduce tear circulation, and create friction every time you blink. A lens made of a material that doesn’t suit your eye can cause similar problems.
Beyond the lens itself, certain medications like antihistamines and some antidepressants can reduce your natural tear production. Seasonal allergies and hormonal changes, particularly during pregnancy or menopause, can also affect how much moisture your eyes produce.
Lens Types and Hygiene Habits That Can Help
Contact Lens Options Worth Exploring
Not all lenses affect your eyes the same way. Silicone hydrogel lenses allow significantly more oxygen through to your cornea compared to older soft lens materials, which can make a noticeable difference in comfort. We’ve written a blog on how contact lenses work to help you understand the different types.
Daily disposable lenses are worth considering if protein buildup is part of your issue. Because you open a fresh pair each morning, there’s no accumulation from previous wear. For more significant dryness, scleral lenses vault over the cornea entirely and hold a reservoir of moisture against the surface of your eyes.
Hygiene Habits That Make a Difference
Small habits add up. Replace your lens case every 1–3 months, as older cases can harbour bacteria that lead to irritation. The American Academy of Ophthalmology’s contact lens care guide offers step-by-step guidance on cleaning, disinfection, and storage worth bookmarking.
- Use a contact solution without harsh preservatives if your eyes tend to react to standard multipurpose formulas. Your Optometrist can recommend a solution that works best for your eyes based on the lens material you wear.
- Never sleep in your contacts, even if your lenses are marketed as extended wear, unless an eye doctor has specifically recommended that you do so.
- Follow your replacement schedule, even when a lens still feels comfortable.
When to See Eye Doctors in Kitchener-Waterloo
Making adjustments at home can help, but it doesn’t always get to the root of the problem. If your symptoms persist after switching contact solutions or shortening your wear time, it’s worth getting a proper contact lens exam to assess the health of your tear film. Based on your individual needs, we can recommend products to help prevent your symptoms, as well as in-office treatment solutions like IPL and radiofrequency, and other dry eye therapies to help address the underlying factors that are contributing to your discomfort.
