What Happens If You Wear Contact Lenses for Too Long?

“I wear my contacts all day, every day. They’re so comfortable that sometimes I forget to take them out!”
 

“I just got a new pair, so I’ll be fine wearing them a little longer.”
 

“I don’t feel any discomfort, so my eyes must be doing okay.”
 

These are all things we hear from patients regularly. Contact lenses are an incredible solution for many, offering freedom from glasses and clear vision on the go. But as comfortable as they are, wearing contacts for too long or without proper care can lead to a range of eye health issues. Overwearing contacts doesn’t just cause discomfort; it can impact your long-term eye health in ways you may not realize.
 

The Risks of Overwearing Contacts

Just like any other part of our body, the eyes need rest and care. Contact lenses restrict the flow of oxygen to the cornea, and extended wear can lead to serious complications. Overwearing contacts can cause:
 

• Dryness and Irritation: Contacts absorb moisture from the eyes, which can lead to dry, itchy, and uncomfortable eyes, especially if worn for extended periods.
   

• Corneal Ulcers: One of the most serious risks, corneal ulcers are painful open sores on the eye that can occur when bacteria, fungus, or other harmful microorganisms infiltrate the cornea.
   

• Infections: Wearing contacts for too long, especially overnight, can introduce bacteria to the eyes. Bacterial, fungal, and even amoebic infections can develop, and without prompt treatment, they can cause scarring and, in some cases, permanent vision loss.
   

• Reduced Corneal Sensitivity: Over time, wearing contacts can reduce corneal sensitivity, making it harder to notice small irritations or issues—sometimes until they become major problems.
   

• Hypoxia (Oxygen Deprivation): Contact lenses act as a barrier to oxygen, and extended wear can deprive the cornea of oxygen, leading to complications such as swelling, redness, and even long-term damage.
   

Preventing Issues with Proper Lens Care

So, what can you do to protect your eyes while enjoying the convenience of contact lenses? A few simple habits can help:
 

1. Follow Your Wear Schedule: Contact lenses are designed with specific wear schedules. Some are meant for daily wear, while others may be designed for two weeks or even a month. It’s essential to adhere to the schedule recommended by your eye care professional.
 

2. Practice Good Hygiene: Always wash your hands thoroughly before handling your contacts. Replace your lens case every few months and clean it regularly to prevent bacterial buildup.
 

3. Avoid Sleeping in Contacts: Unless your contacts are specifically designed for extended wear, remove them before bed. Overnight wear increases the risk of infection as the closed eyelids reduce oxygen flow to the eyes.
 

4. Take Breaks When Possible: Give your eyes a rest by wearing glasses for part of the day. This can relieve eye dryness and help ensure your eyes receive enough oxygen.
 

5. Use Proper Solution: Avoid using tap water or saliva to clean your contacts. Always use a recommended lens solution, and don’t “top off” your case; replace the solution entirely each time.
 

Why Regular Eye Exams Matter

You may feel fine, but regular eye exams are essential to ensure your eyes stay healthy, especially if you’re a contact lens wearer. Even without noticeable discomfort, your eyes could be developing issues that only a professional can detect. Eye exams provide more than just a prescription; they allow your eye doctor to check for early signs of infection, dryness, or other complications from contact lens use. A comprehensive eye exam will include:
 

• Corneal Health Check: Ensuring your cornea isn’t showing signs of distress, such as scratches, dryness, or early indicators of ulcers.
   

• Fit and Comfort Assessment: Your eye doctor can assess whether your current lenses are still the best fit for your eyes or if a different type might be healthier for long-term use.
   

• Evaluation of Oxygen Flow: Using imaging and light tests, an eye doctor can evaluate how well oxygen is reaching your cornea, helping to prevent hypoxia and other oxygen-related complications.
   

Keep Your Eyes Healthy and Comfortable

Just because you can see well doesn’t mean your eyes are healthy. Contact lens wear requires vigilance and consistent care to prevent complications. Regular eye exams are a vital part of keeping your vision—and your eyes—in great shape.
