Do Contact Lenses Affect Eye Health? What You Need to Know

At Merivale Vision Care, we understand that contact lenses offer a convenient and versatile alternative to traditional eyeglasses. They're an excellent choice for those seeking clear vision without the hassle of frames. 

However, we're often asked, "Do contact lenses affect eye health?" It's an important question and one we're happy to address. 

In this blog, we'll explore the impact contact lenses can have on your eyes and provide guidance on maintaining optimal eye health.

The Benefits of Contact Lenses

Before we address potential concerns, let's acknowledge the advantages of contact lenses. They offer an unobstructed field of vision, making them perfect for athletes, outdoor enthusiasts, and anyone who prefers a glasses-free look. 

Modern lenses are designed with advanced materials to promote comfort and oxygen flow to the eyes, ensuring they're often suitable for extended wear.

Thanks to technological advancements, today's contact lenses are more breathable and customizable than ever. 

Specialized options, like multifocal and toric lenses, cater to specific vision needs, while daily disposables provide an ultra-hygienic solution for busy lifestyles. Considering these benefits, it's easy to see why millions choose contact lenses.

How Contact Lenses Affect Eye Health

While contact lenses are safe for most users, they're not without risks. Here are some potential effects of contact lenses on eye health:

‍

Reduced Oxygen to the Cornea

The cornea, the clear, outermost layer of your eye, gets its oxygen directly from the air. Contact lenses cover the cornea, which can reduce the amount of oxygen reaching this essential tissue. 

Over time, insufficient oxygen can lead to complications like corneal swelling (edema) or neovascularization, where new blood vessels grow into the cornea.

Modern lenses made from silicone hydrogel allow significantly more oxygen to pass through than older materials. Choosing high-quality lenses and following your optometrist's wear schedule can minimize these risks.

Dry Eye Symptoms

Contact lenses can absorb tears, which may leave some wearers feeling like their eyes are dry or irritated. 

This is especially true for individuals who already experience dry eye syndrome or spend extended periods in environments with low humidity, such as air-conditioned offices.

Using lubricating eye drops specifically designed for contact lens users can alleviate discomfort. Additionally, taking breaks from lens wear and using glasses periodically can allow your eyes to rehydrate naturally.

‍

Risk of Infections

One of the most significant concerns with contact lenses is the risk of eye infections. Poor hygiene, such as not washing your hands before handling lenses or sleeping in them when not advised, can introduce harmful bacteria to your eyes. 

This can lead to conditions like conjunctivitis or, in rare cases, more severe infections like keratitis.

Adhering to proper lens care is key to avoiding infections. Regularly replacing your lenses, using the correct cleaning solutions, and following your optometrist's recommendations are critical to maintaining eye health.

‍

Allergic Reactions

‍

Some people may develop allergic reactions to the materials in contact lenses or the preservatives in lens cleaning solutions. Symptoms may include redness, itching, or a feeling of grittiness in the eyes.

If you experience these symptoms, consult your optometrist immediately. Switching to a different lens type, such as daily disposables or lenses made from hypoallergenic materials, may resolve the issue.

How to Keep Your Eyes Healthy While Using Contact Lenses

Contact lenses can be a safe and effective vision solution if you follow a few essential guidelines. Here's how we recommend maintaining your eye health:

‍

Follow the Wear Schedule

Each type of contact lens comes with a specific wear schedule. Some lenses are designed for daily wear and should be discarded after a single use, while others can be worn for extended periods. 

Wearing your lenses longer than recommended can increase the risk of complications. Always follow the schedule provided by your optometrist. If unsure, ask us during your next visit—we're here to help.

‍

Practice Good Hygiene

Hygiene is paramount when it comes to contact lens use. Wash and dry your hands thoroughly before handling your lenses, and use a fresh cleaning solution each time you store them. Never use tap water or saliva to clean your lenses, as these can introduce harmful bacteria.

‍

Take Lens-Free Breaks

Your eyes need time to rest and recover, especially if you wear contact lenses for extended periods. Consider alternating between contact lenses and glasses, particularly when you're at home or don't require extended wear.

‍

Use Artificial Tears if Needed

If you experience dryness, use lubricating drops specifically formulated for contact lens wearers. Avoid over-the-counter drops that aren't labelled as safe for contact lenses, as they may cause cloudiness or discomfort.

‍

Schedule Regular Eye Exams

Routine eye exams are essential for contact lens wearers. During your visit, we can assess your eye health, ensure your lenses fit correctly, and make necessary adjustments to your prescription. Regular check-ups help you catch potential issues early and keep your eyes healthy for years.

‍

When to Seek Help

While most people can wear contact lenses without issues, it's crucial to be vigilant about changes in your eye health. Seek immediate care if you notice:

• Persistent redness or irritation
• Pain or discomfort that doesn't improve after removing your lenses
• Blurry vision or unusual discharge

These symptoms could indicate an infection or other complications that require prompt attention. At Merivale Vision Care, we're committed to providing you with expert care when you need it most.
