Long-term Contact Lens Wear and Eye Fatigue: Causes and Solutions

Have you noticed that your vision gets blurry and your eyes feel tired around 2 PM after wearing contacts from morning, around 6 AM? This issue is not uncommon among contact lens wearers. Here, we discuss potential reasons and provide solutions to address the problem.

Understanding the Problem

It is not uncommon for contact lens wearers to experience tired eyes and blurry vision after several hours of use. Below are some potential causes:

Dryness

Contacts, especially when worn for long periods, can cause dryness. This can lead to discomfort and blurred vision. Dryness is a common complaint among contact lens wearers, and it can be exacerbated by environmental factors such as low humidity, screen time, or wearing contacts without breaks.

Oxygen Permeability

Some types of contact lenses may not allow enough oxygen to reach the corneas. This can be particularly concerning, as corneas need a steady supply of oxygen to function properly. Insufficient oxygen can cause fatigue and discomfort, potentially leading to even more serious issues if left untreated.

Lens Build-up

Protein deposits or debris can accumulate on your lenses throughout the day. This can affect vision clarity and cause discomfort. It is important to clean your lenses regularly to prevent build-up. Daily cleaning routines and appropriate lens care are crucial for maintaining a healthy vision.

Allergies

Environmental factors, such as pollen or dust, can contribute to eye fatigue and irritation. If you have a history of allergies, it is essential to take this into account when experiencing discomfort or blurred vision.

Improper Fit

If your lenses do not fit properly, they may cause discomfort and vision issues. An improper fit can disrupt the natural curve of the cornea and lead to visible strain in your eyes.

Recommendations for Addressing the Issue

To alleviate tired eyes and blurry vision, consider the following recommendations:

Take Breaks

Take short breaks every hour to remove your contacts and allow your eyes to rest. A 15- to 30-minute break can provide much-needed respite and help maintain eye health and vision clarity.

Use Rewetting Drops

Over-the-counter rewetting drops can help alleviate dryness and discomfort associated with contact lens wear. These drops can be used throughout the day to keep your eyes lubricated and comfortable.

Consider Different Lenses

Consult your eye care professional about different types of lenses. Options such as daily disposables, silicone hydrogels, or air permeable RGP (Rigid Gas Permeable) lenses may provide greater comfort and oxygen permeability, reducing the likelihood of fatigue and blurred vision.

Limit Wear Time

If you consistently experience discomfort, consider reducing the amount of time you wear your contacts each day. This can help prevent long-term damage to your eyes and protect your vision.

Finding the Right Solution

If you notice these symptoms persisting, it is important to consult with an eye care professional. They can help rule out any underlying conditions and provide tailored solutions. For instance, if the issue is due to a specific type of contact lens material or design, they may suggest switching to lenses with superior oxygen permeability and comfort features.

Remember, your eye health and vision are paramount. Regular eye check-ups and proper lens care can significantly reduce the risk of eye-related issues. If you are experiencing ongoing discomfort or blurred vision, it is crucial to address the problem before it leads to more serious complications.
