Myths about Contacts

The Truth About “Contact Lens Myths” Everyone Believes

Contact lenses have transformed how millions of people see the world. They offer freedom from glasses, flexibility for sports and active lifestyles, and even cosmetic options for those who want to change their eye color. Yet despite their popularity, contact lenses are surrounded by myths and misconceptions that make some people hesitant to try them—or worse, lead current wearers into unsafe habits.

As an Optometrist and an Optician, we hear these myths every day. From “contacts can get lost behind your eye” to “you can reuse daily disposables,” misinformation spreads quickly and can cause unnecessary worry or risky behavior. In this article, we’ll bust the most common contact lens myths and set the record straight with science, eye health expertise, and practical advice.

Myth #1: A Contact Lens Can Get Lost Behind Your Eye

The truth: It’s physically impossible for a contact lens to slip behind your eye.

Here’s why: your eye is protected by a thin, clear membrane called the conjunctiva, which folds back and connects to the inside of your eyelids. Think of it as a natural barrier that seals off the space behind your eyeball. A contact lens may slide out of place—like moving under your eyelid if it shifts—but it will never disappear behind your eye.

If your contact feels “lost,” it may just be stuck under the upper eyelid or folded. A few lubricating eye drops and gentle blinking usually help bring it back into position.

Myth #2: You Can Sleep in Any Contact Lenses

The truth: Only specific lenses are FDA-approved for overnight wear, and even those come with risks.

Sleeping in contacts reduces oxygen supply to your cornea, creating a perfect environment for bacteria to thrive. Studies show that sleeping in contacts increases the risk of serious eye infections, such as microbial keratitis, by 6–8 times.

Some brands manufacture “extended wear” contacts designed for occasional overnight use, but most optometrists still recommend removing your lenses before bed. It’s one of the simplest steps you can take to protect your vision for life. Dr. Jensen typically recommends Biofinity, Total 30, Acuvue Vita or Oasys lenses for extended wear.

Myth #3: Daily Disposables Can Be Worn for Several Days

The truth: “Daily” means daily.

Daily disposable lenses are engineered for one-time use. Their thin material is designed for comfort but isn’t durable enough for repeated wear. Reusing them can lead to:

• Lens breakdown and tearing

• Protein and bacteria buildup

• Increased risk of infections

While it might feel tempting to “stretch” your supply, doing so risks your eye health. If you want a longer-lasting option, ask your optometrist about biweekly or monthly lenses.

Myth #4: Contact Lenses Are Uncomfortable

The truth: Modern contact lenses are more comfortable than ever.

Many people who tried contacts years ago still believe they’re scratchy or irritating. But technology has advanced dramatically:

• Silicone hydrogel materials allow more oxygen to reach your eyes.

• Moisture-locking designs reduce dryness.

• Custom fits ensure lenses match the shape of your cornea.

• Oasis products help in Colorado's dry climate to keep contacts comfortable. Dr. Jensen is also well versed in dry eye management should comfort become an issue. He works with Oasis dry eye products to ensure a healthy cornea.

If you’ve avoided contacts because you think they’re uncomfortable, it may be time to give them another try. An optometrist can fit you with lenses that feel natural and comfortable all day long.

Myth #5: Contacts Are Too Difficult to Put In and Take Out

The truth: Insertion and removal are easy with a little practice.

At first, handling contacts can feel intimidating. But most patients master the process within a week. Dr. Jensen and Alicia can provide hands-on training, and there are plenty of tips to make it easier:

• Always start with the same eye to avoid mix-ups.

• Use your fingertip, not your fingernail.

• Keep your eyes relaxed and avoid blinking forcefully.

Once you get into a routine, it takes less than a minute to insert or remove your lenses. For most wearers, it becomes second nature.

Myth #6: Children Are Too Young for Contact Lenses

The truth: There’s no strict age limit for contact lenses—it depends more on responsibility than age.

Studies show that children as young as 8 years old can safely wear contacts if they follow hygiene instructions.

Contacts can be especially helpful for young athletes who struggle with glasses during sports. Plus, specialized contact lenses are now available for myopia control, which may help slow the progression of nearsightedness in children.

Myth #7: Contacts Can Fall Out Easily

The truth: Properly fitted contacts rarely fall out.

Unlike the hard lenses of decades past, modern soft lenses adhere gently to the tear film on your eye. They’re designed to move slightly for oxygen exchange but stay in place during normal activities—even running, dancing, or playing sports.

If your lenses are frequently slipping out, it could be a sign of poor fit or dryness. An optometrist can adjust your prescription or lens type to fix the issue.

Myth #8: Contacts Can Get Stuck in Your Eye Forever

The truth: A lens might stick temporarily, but it can always be removed.

Dry eyes, improper insertion, or sleeping in contacts can sometimes cause a lens to feel stuck. Using a few lubricating drops and gently massaging the eyelid usually loosens it. In stubborn cases, your optometrist can help—but rest assured, it won’t be “stuck forever.”

Myth #9: Wearing Contacts Will Make Your Eyes Weaker

The truth: Contact lenses don’t change your prescription.

Contacts are simply a tool to correct refractive errors—nearsightedness, farsightedness, or astigmatism. They don’t make your eyes “dependent” on them. Vision changes over time are usually due to natural aging or progression of conditions like myopia, not from wearing contacts.

Myth #10: You Don’t Need to Clean Your Contact Lens Case Often

The truth: Your case needs daily care, too.

Lens cases are a major source of contamination. Studies show that up to 70% of cases contain harmful bacteria if not cleaned regularly. To protect your eyes:

• Rinse the case daily with fresh contact lens solution (never tap water).

• Let it air dry face down.

• Replace your case every 1–3 months.

Good case hygiene is just as important as cleaning your lenses themselves.

Myth #11: Colored Contact Lenses Are Just for Fun and Don’t Need a Prescription

The truth: All contact lenses—colored or clear—require a prescription.

Even non-corrective “cosmetic” lenses sit directly on your cornea. If they don’t fit properly, they can cause scratches, infections, or even vision loss. Buying decorative lenses from costume shops or online retailers for Halloween without a prescription is risky.

If you want to safely change your eye color, your optometrist can fit you with FDA-approved colored contacts.

Myth #12: You Can Clean Contacts With Water or Saliva

The truth: Only use approved contact lens solution.

Tap water, bottled water, or saliva all contain microorganisms that can cause serious infections. A common one is Acanthamoeba keratitis, a painful, sight-threatening infection linked to improper lens hygiene. This is another reminder to not shower with your contacts.

Always clean and store your lenses in fresh solution—not water, not saliva, and not reused fluid.

The Bottom Line: Facts Over Fiction

Contact lenses are safe, effective, and life-changing when used properly. Most of the fears people have about them come from outdated information or urban legends. By debunking these myths, we hope to encourage better lens habits and help more people enjoy the freedom of clear, comfortable vision.

If you’re curious about contacts—or struggling with your current ones—the best step is to schedule an appointment with Dr. Jensen. He will evaluate your eye health, recommend the right type of lens for your lifestyle, and teach you proper care routines.

Your vision is too important to risk on myths. Stick with the facts, follow expert advice, and you’ll discover why millions of people around the world trust contact lenses every day.
