Do Contact Lenses Damage the Cornea Over Time?

/0 Comments/in ,

Many people prefer contact lenses in Peoria, IL for their convenience and natural look, but there’s an ongoing concern about whether years of wear might harm the cornea—the clear, curved layer that helps focus light. While contacts are safe for most patients, the way they’re worn and cared for makes a big difference. The cornea is delicate, and small lapses in hygiene or overuse can lead to irritation or long-term changes if ignored.

How Contact Lenses Interact With the Cornea

The cornea doesn’t have blood vessels—it relies on oxygen from the air. A contact lens, though thin and flexible, still limits how much oxygen reaches the surface. Over time, this reduced airflow can cause dryness or swelling, especially if lenses are worn too long each day.

Modern lenses made from silicone hydrogel materials allow much higher oxygen permeability, which greatly lowers these risks. Still, wearing them overnight, even occasionally, can stress the cornea. In extreme or prolonged cases, low oxygen levels can trigger tiny blood vessels to grow toward the cornea, a process called neovascularization. It’s reversible if caught early but serious if neglected.

The Real Risks: Hygiene and Habits

Most damage doesn’t come from the lenses themselves but from how they’re handled. Using the same pair beyond its intended life, rinsing them in tap water, or reusing cleaning solution all raise the risk of infection. Bacterial or fungal infections can scar the cornea and permanently affect vision.

Even casual habits—like showering or swimming with contacts—introduce microorganisms that don’t belong in the eye. These organisms cling to lenses and can cause painful inflammation if they reach the cornea.

How to Keep Your Corneas Healthy

Good lens hygiene is the best protection. Replace lenses on schedule, clean them properly, and let your eyes rest when they feel dry or irritated. Regular optometry visits also allow early detection of oxygen-related changes or early infection.

Worn responsibly, contact lenses are perfectly safe. The cornea’s health depends not on how long you’ve worn lenses, but on how well you care for them day to day—small habits that make a big difference in lifelong comfort and vision.

Basic Tips for Managing an Eye Disease

/0 Comments/in , ,

Eye diseases and conditions can run from mundane to serious. For example, maybe you get dry eyes from time to time, but that’s easily managed with a few over-the-counter eye drops. For other cases, managing an eye disease is more complicated. Here, we look at a few tips that can not only help you manage your visual health but potentially even mitigate risk or improve it.

The Nature of Eye Diseases

While some common eye diseases can be cured outright, like pink eye or styes, others will need to be managed by both you and an eye doctor in Kewanee, IL. This will mean a daily effort on your part to ensure that you can keep your vision in check as it progresses, though thankfully, any changes you’ll need to make will be fairly standard (meaning you may not need to make a huge shift in your life).

What You Can Do

Most of managing an eye disease is straightforward:

  • Follow your doctor’s treatment plan
  • Eat a balanced, nutrient-rich diet
  • Wear protective eyewear in the sun
  • Avoid long periods of screen time or intense focus (e.g., take a break every 20 minutes)
  • Keep an eye on any changes in your vision

Of course, just because the tips are easy to understand doesn’t always mean that they’re easy to do. For example, you may need to start eating more leafy greens or quit smoking, which are healthy changes that even those without an eye disease should do.

These habits are often difficult to instill when you’re young, let alone when you’re old enough to get a condition like glaucoma. This is why it can be so important to make small changes in your life, such as wearing prescription sunglasses from time to time or setting alarms when you’re on your phone.

What Is FDA-Approved Myopia Management?

/0 Comments/in , ,

The FDA reviews a number of different treatments and solutions every year for disorders across the spectrum. If you’re interested in the administration’s official stamps of approval for myopia management, it’s worth knowing which products they endorse. Here, we’ll look at not just why they signed off, but also where you can find FDA-approved myopia management solutions in Kewanee, IL.

Can an Optometrist Stop or Correct Nearsightedness?

Myopia, also known as nearsightedness, is a common condition affecting many people. It can be caused by anything from genetic factors to prolonged exposure to insufficient lighting to diabetes. For the most part, it was treated as a naturally occurring condition that could be controlled with either eyeglasses or contact lenses.

However, there have been numerous researchers and companies attempting to change this narrative. Optometrists in Kewanee, IL looked for ways to not just manage it, but stop it from getting worse. The rate of myopia progression varies based on a person’s eye health, which can be influenced by factors such as their diet and environment.

Which Products Have the FDA Approved?

There are three major products for myopia management:

  • MiSight: This relatively new product was approved for kids between 8 and 12 in 2019. They are soft, single-use lenses that are designed to not just correct vision but actively slow the progress of myopia. The lenses work by signaling the child’s developing eye to stop elongating, thus preventing further myopia.
  • Ortho-K Lenses: Ortho-K was approved in 2002, and they work by reshaping the cornea. They’re thought to control myopia progression by altering the retina’s processing of peripheral light.
  • SightGlass: Approved in 2024, SightGlass scatters light rays across the retina. Much like Ortho-K, this is meant to prevent myopia from getting worse.

Every FDA approved solution taps into the same general benefit: signaling the eye to stop elongating. However, when each patient reacts to these solutions differently, it’s not always easy to estimate the impact of the investment.

How Do I Know If I Have Low Vision?

/0 Comments/in ,

Low vision is not necessarily a well-known term for many people, which is why it’s easy to confuse the term if you’re unaware of the disorder. Here, we’ll look at what low vision is, who it’s likely to affect, and what you can do if you think you have it.

The Fast Facts of Low Vision

Low vision in Kewanee, IL is a type of visual impairment that can’t be corrected with traditional means, such as glasses or surgery. Low vision is typically a symptom of a larger eye disorder, such as glaucoma or age-related macular degeneration.

Do I Have Low Vision?

Typically, low vision is a gradual process, meaning you wouldn’t experience low vision if there wasn’t a corresponding cause. If you have temporary blindness, this can be caused by a temporary disorder, such as a concussion or a migraine.

Is Low Vision the Same Thing as Legally Blind?

No. Low vision refers to a general visual impairment while legal blindness contains a specific definition (20/200 visual acuity). So, while you might have low vision in addition to legal blindness, you can have low vision without being legally blind.

What Are the Symptoms of Low Vision?

You might think of low vision as the inability to see, but it can manifest in a few different ways:

  • Blurriness: Even with high-grade prescription glasses, objects may appear blurry or otherwise unclear.
  • Sensitivity: People with low vision will have problems adapting to and processing light, which can make them extremely sensitive to brightness of any kind (e.g., natural, artificial, etc.).
  • Eye strain and headaches: The more effort your eyes have to make, the more likely you’ll feel the stress in different ways.

What Can Be Done for Low Vision?

If glasses, contact lenses, and surgery won’t do the trick, you’ll need to visit an eye doctor in Kewanee, IL who specializes in this disorder. At Illinois Vision Clinic, we can help you learn more about low-vision rehab and low-vision devices, all of which can potentially help you enhance your vision and independence. Plus, we can provide emotional support and counseling to help you cope with the changes.
