What Causes Dry Eyes with Contacts?

While contacts offer incredible convenience, they sit right on the surface of your eye and change how your natural tears function. This disruption can quickly lead to irritation, redness, and discomfort.

Contact lenses can cause dry eyes by limiting the oxygen that reaches your cornea and pulling moisture directly from your tear film. Fortunately, understanding why this happens is the first step toward finding comfortable, long-lasting relief.

Common Dry Eye Symptoms in Contact Lens Wearers

Dry eyes don’t always feel “dry.” The sensations can be surprising and easy to dismiss at first. Look out for these common signs:

• Burning, stinging, or a gritty feeling, like something is caught in your eye
• Redness
• Blurry vision that comes and goes during wear
• Eye fatigue
• Watery eyes
• Sensitivity to light, especially indoors

You might notice symptoms creep up as the day goes on. That’s not a coincidence. Tears thin out with time, and certain habits speed up the process.

Screen time is a major factor. When you focus on a monitor, your blink rate drops significantly, reducing how often your tears spread across the eye. Dry or air-conditioned spaces make this worse by pulling moisture out of the air, and off the surface of your eye, faster than it can replenish.

Why Your Lenses Are Drying Your Eyes

Some of the most common contact habits quietly make dry eye symptoms worse over time:

• Wearing lenses longer than your optometrist recommends
• Skipping proper lens cleaning, which allows deposits to build up on the lens surface
• Using contact solutions that contain preservatives, which can irritate sensitive eyes
• Sleeping with your contact lenses in your eyes
• A poor fit or outdated prescription can increase friction and worsen dryness.

It’s not always about the lens itself. Your body plays a role, too.

Certain medications can reduce the number of tears your eyes naturally produce. Hormonal changes, especially around pregnancy or menopause, also affect tear film quality.

Additionally, if you’re 40 or older, your risk for dry eye naturally increases regardless of whether you wear contacts.

Contact Lens Options That Help Reduce Dryness

Even if you have dry eye, you don’t have to give up on contacts entirely. Not all lenses put equal strain on your tear film, and some are designed with dryness in mind, including:

• Silicone hydrogel lenses: These allow significantly more oxygen to reach the cornea compared to traditional soft lenses.
• Daily disposables: Since you wear a completely new pair of lenses every day, these reduce the buildup of proteins and deposits that irritate dry eyes. You also don’t need to use a solution. Many modern daily disposable lenses also offer excellent oxygen transmission for improved eye health and comfort.
• Scleral lenses: These larger than normal lenses rest on the white of the eye and hold a layer of fluid over the cornea all day, which can offer comfort for people with more persistent dryness.

The products you use with your lenses matter just as much as the lenses themselves. Choose preservative-free artificial tears to safely hydrate your eyes without damaging the lens. Switch to hydrogen peroxide-based cleaning systems for a gentler option if your eyes react to the preservatives in multipurpose solutions.

When shopping for contact lenses, be cautious of low-cost lenses sold primarily online. Some use older lens materials that may not deliver as much oxygen to the cornea as newer silicone hydrogel designs. A lower price can sometimes come at the expense of comfort, breathability, and long-term eye health.

Practical Tips for Everyday Relief

A few small adjustments to your routine can go a long way.

• Drink enough water throughout the day. Dehydration affects tear production.
• Add omega-3 fatty acids to your diet through foods like salmon, walnuts, or flaxseed. A lack of Omega-3s can damage the oily layer of your tear film.
• Run a humidifier in rooms with dry air, especially in air-conditioned offices or during colder months.
• Give your eyes a break by wearing glasses some days. Reducing total contact lens wear time helps your tear film recover.

Also, for anyone working long hours at a desk, take extra care to give your eyes regular breaks. Use the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.

Reclaim Your Comfort and Clear Vision

Dry eyes with contacts don’t have to be a daily struggle. The right combination of lens type, care routine, and small lifestyle habits can make a real difference in how your eyes feel.

If your symptoms are getting harder to manage, a professional evaluation can help you find a customized approach that fits your needs. Schedule a dry eye evaluation with Pro-Optix Optometry & Dry Eye Center and get back to wearing your contacts in comfort.
