Myths and Facts about Contact Lenses

Contact lenses have revolutionized the world of vision correction. Offering a convenient and often more aesthetically pleasing alternative to glasses, they have become a staple for millions worldwide. Their popularity stems from the freedom they offer: the ability to play sports without hindrance, wear non-prescription sunglasses, and enjoy a wider field of unobstructed vision.

However, with this widespread use comes a myriad of myths. Misinformation and misconceptions about contact lenses abound, leading to confusion and sometimes even misuse. This article aims to debunk some of the most common myths and set the record straight.

Myth 1: Contact Lenses Can Get Permanently Stuck to Your Eyes

The Facts: With proper care and usage, lenses cannot get "stuck" permanently.

Explanation: The human eye is designed with its own protective mechanisms. One such mechanism is the production of tears, which lubricate the eye. This natural lubrication ensures that, under normal circumstances, a contact lens cannot adhere permanently to the eye's surface. Modern lenses are also designed with materials that are compatible with the eye's natural environment, further reducing any risk. While a lens might feel "stuck" occasionally, especially if the eye is particularly dry, with proper hydration and gentle manipulation, it can be easily moved or removed.

Myth 2: Contact Lenses Are Uncomfortable

The Facts: Modern lenses are designed for comfort, and discomfort usually indicates a problem.

Explanation: The contact lens industry has seen significant advancements over the years. Today's lenses are crafted using sophisticated materials that promote breathability, moisture retention, and flexibility. Silicone hydrogel lenses allow more oxygen to reach the cornea leading to enhanced comfort. If a wearer experiences discomfort, it's often a sign of an ill-fitting lens, an allergic reaction, or an underlying eye condition, all of which warrant a consultation with an optometrist.

Myth 3: Wearing Contact Lenses Causes Eye Problems

The Facts: When used correctly, contact lenses are safe.

Explanation: Like any medical device, contact lenses come with guidelines for safe use. Problems typically arise from non-compliance with these guidelines. Over-wearing lenses, not cleaning them properly, or using expired solutions are all factors which can lead to complications. However, when used as directed, and with regular eye check-ups, contact lenses are a safe and effective vision correction tool.

Myth 4: Contact Lenses Can Pop Out of Your Eye Easily

The Facts: Properly fitted lenses remain securely in place under most conditions.

Explanation: The fear of contact lenses popping out is rooted in misconceptions and perhaps outdated experiences. Modern contact lenses are designed based on extensive research and technological advancements. During an eye exam, the eyes are meticulously measured and examined. Therefore, when prescribed by an optometrist, the lenses are tailored to fit the unique curvature and diameter of an individual's eye. This customization ensures that the lens sits comfortably and securely.

The lens and the eye's natural tear film create a kind of suction, keeping the lens in place. While high-impact activities or rubbing the eyes might momentarily dislodge a lens, it's rare for a lens to simply just "pop out" during regular activities. For those with this particular concern, daily practices like proper insertion, removal, and ensuring the lens isn't inside-out can further mitigate such risks.

Myth 5: Best Brands for Dry Eye Contacts

Myth 6: Only Adults Can Wear Contact Lenses

The Facts: People of all ages, including children and teenagers, can wear contact lenses.

Explanation: The notion that only adults can wear contact lenses is outdated. With advancements in lens technology and materials, even children and teenagers can benefit from them. Pediatric optometrists often prescribe contact lenses for kids for various reasons, including specific eye conditions, sports activities, or even self-esteem issues related to wearing glasses. For young athletes, contact lenses offer an unobstructed field of vision and eliminate the risk of glasses-related injuries. However, the primary consideration for their eligibility is dependent on the child's discipline and ability to care for the lenses responsibly, while adhering to a proper wear schedule in accordance with the lens type. With proper guidance and regular check-ups, contact lenses can be a safe and effective vision solution for younger individuals.

Myth 6: Contact Lenses Are Too Expensive

The Facts: There are a variety of lenses available at different price points.

Explanation: The cost of contact lenses can vary widely based on type, brand, and prescription needs. While it's true that certain specialty lenses, like those for presbyopia or severe astigmatism, might come with a heftier price tag, many standard lenses are quite affordable. Daily disposables, which are gaining popularity due to their convenience and reduced risk of infection, might seem expensive at first glance. However, when you factor in the savings from not needing cleaning solutions or storage cases, they can be cost-effective in the long run. Additionally, many manufacturers offer rebates or bulk purchase discounts. It's always a good idea to discuss budget and lifestyle needs with an optometrist, as they are able to recommend the best lens type for both vision and financial considerations.

Myth 7: You Can't Wear Contact Lenses If You Have Astigmatism

The Facts: Toric lenses are designed specifically for those with astigmatism.

Explanation: Astigmatism arises from an irregularly shaped cornea or lens inside the eye, causing blurred or distorted vision. There's a misconception that this irregularity makes it impossible for contact lenses to fit properly. However, with the advent of toric contact lenses, this is no longer the case. Toric lenses have a unique design that allows them to align perfectly with the irregular shape of an astigmatic eye. They have different optical powers within different lens meridians, compensating for the uneven curvature causing astigmatism. These lenses also have stabilization mechanisms to prevent them from rotating, ensuring clear and stable vision. With toric lenses, individuals with astigmatism can enjoy the benefits of contact lenses just as those with standard prescriptions do.

Myth 8: It's Okay to Clean Contact Lenses with Water

The Facs: Only sterile solutions should be used to clean and store lenses.

Explanation: While tap water undergoes treatment to make it safe for consumption, it is not sterile. It can contain a variety of microorganisms, including bacteria, viruses, and amoebas. One particularly dangerous microorganism found in water is Acanthamoeba, which can lead to a severe, painful, and sight-threatening infection called Acanthamoeba keratitis. When contact lenses are rinsed or stored in tap water, these microorganisms can adhere to the lens. When the lens is then placed on the eye, the suction of the contact lens meant to fit the contact to the eye can act as a vehicle, introducing these pathogens directly to the eye's surface. This can lead to infections, some of which can be severe and potentially sight-threatening. To ensure the safety and longevity of both the contact lenses and the health of the eyes, it's imperative to use only commercially prepared and sterile solutions specifically designed for contact lens care.

Myth 9: Sleeping in Contact Lenses Is Harmless

The Facs: Not all lenses are designed for overnight wear.

Explanation: The eye is a living organ that requires oxygen to function correctly. While some advanced contact lenses are designed to let more oxygen pass through them, many traditional lenses can limit this essential oxygen flow, especially when the eyelid is closed during sleep. Extended wear lenses are specifically designed to be breathable enough for overnight wear. However, even with these lenses, there's an increased risk of eye infections. When lenses are worn during sleep, the reduced oxygen can cause the cornea to swell, making it more vulnerable to bacteria. Over time, consistently sleeping in lenses not designed for overnight wear can lead to complications like corneal infections, corneal ulcers, and even vision loss. It's always best to consult with an optometrist about the safety and suitability of sleeping in specific contact lenses.

Myth 10: Contact Lenses Can Be Shared Among Friends

The Facs: Lenses are personal items and should never be shared.

Explanation: Sharing contact lenses might seem like a harmless act, especially if it's just for a short period or for cosmetic reasons. However, this practice comes with an array of risks. Every individual's eyes have their unique set of bacteria, most of which are harmless in their own eyes. But when transferred to another person's eye, this bacteria can cause infections. Additionally, each contact lens is fitted to the specific measurements of an individual's eye. Wearing a lens that isn't fitted correctly can cause discomfort, abrasions, and a variety of other eye injuries. Moreover, there's a risk of transferring any pathogens or debris present on the lens from one eye to another. Sharing contact lenses is akin to sharing personal items like toothbrushes, but can be much worse in some cases; it's unsanitary and can lead to health complications.

The Bottom Line

In the realm of vision correction, contact lenses have emerged as a preferred choice for many, offering both convenience and a break from the confines of eyeglasses. However, with their popularity comes a wide variety of myths and misconceptions. Many of these myths can lead to improper use, potential health risks, and even deter some from benefiting from contact lenses altogether. It's crucial to separate fact from fiction to ensure the safety and effectiveness of lens use.

While the internet and word-of-mouth can offer a plethora of information, not all of it is accurate or applicable to every individual. Hence, the role of eye care professionals is always paramount. Consulting with optometrists or ophthalmologists provides tailored advice, accurate information and guidance specific to one's eye health and needs. In the end, when it comes to the health of our eyes, relying on expert guidance and evidence-based practices is the only clear way forward.
