Many people rely on contact lenses to correct their vision. They offer a more convenient and often more comfortable alternative to glasses, but they also come with risks.

One of the biggest dangers associated with contact lens wear is leaving them in for too long. Here are just a few of the problems that can arise when contacts are worn for extended periods of time:.

1. Corneal Abrasions

One of the most common problems associated with wearing contacts for too long is corneal abrasions. This occurs when the contact lens rubs against the surface of the eye, causing a scratch or cut.

These abrasions can be extremely painful and can even lead to a corneal ulcer, which can cause permanent scarring and vision loss.

2. Infections

Wearing contact lenses for an extended period of time can increase your risk of developing an eye infection.

Bacteria can accumulate on the surface of the lens, and if not properly cleaned or disposed of, can cause serious and potentially sight-threatening infections like conjunctivitis, keratitis, and even endophthalmitis.

3. Dry Eye

Wearing contacts for too long can also cause dry eye. Because the lenses sit directly on the eye, they can block the flow of oxygen and other nutrients to the cornea, leading to decreased tear production.

This can cause the eyes to feel dry, itchy, and uncomfortable.

4. Red Eye

If your eyes appear red or bloodshot after wearing contact lenses for an extended period of time, it could be a sign that your eyes are overworked and are not receiving enough oxygen.

This can lead to a condition called corneal neovascularization, which is the growth of new blood vessels in the cornea. This can increase the risk of infection and further damage to the cornea.

5. Reduced Vision

Wearing contact lenses for too long can also lead to a reduction in vision. This can be due to corneal scarring, infections, or even changes in eye shape.

In some cases, the damage can be permanent and may require surgery or other corrective measures to restore vision.

6. Contact Lens Intolerance

If you wear contact lenses for too long, your eyes may start to become irritated, inflamed, and uncomfortable. This can lead to an intolerance to contact lenses, meaning that you may no longer be able to wear them at all.

This can be a frustrating and inconvenient problem, especially if you have come to rely on contacts for your vision correction.

7. Itchy, Watery Eyes

Wearing contact lenses for too long can also cause your eyes to become itchy and watery. This can be due to a buildup of bacteria, dirt, and other debris on the surface of the lens.

If left untreated, this can lead to more serious eye infections and other complications.

8. Contact Lens Deposits

If you wear your contact lenses for an extended period of time, they can accumulate deposits on the surface of the lens. This can make them more difficult to clean and can lead to reduced visual acuity and discomfort.

In some cases, the buildup can even cause the lens to become cloudy and opaque, making it impossible to see through.

9. Discomfort and Fatigue

Wearing contact lenses for too long can also cause discomfort and fatigue. This can make it difficult to focus on tasks like reading or using the computer, and can even lead to headaches and other problems.

If your contacts feel dry, uncomfortable, or itchy, it may be time to give your eyes a break.

10. Eye Strain and Headaches

Prolonged contact lens use can also cause eye strain and headaches. This can be due to a variety of factors, including reduced oxygen flow to the cornea, changes in eye shape, and increased pressure on the eye.

If you experience frequent headaches or strained eyes, it may be time to talk to your eye doctor about alternatives to contact lenses.

While contact lenses offer many benefits, they can also pose serious risks if worn for too long.

To avoid these problems, it is important to follow proper care and cleaning instructions, and to never wear your contacts for longer than recommended by your eye doctor.
