Wearing contact lenses is meant to provide clear and comfortable vision, but what happens when your sight turns blurry? Let’s discuss the potential issues behind blurry contact lenses and how they can be resolved for you to enjoy sharp vision.

What is blurry vision?

Blurry vision is when the environment around you appears hazy or unclear. It can impact daily life activities and obstruct the ability to see fine details. The situation may worsen when your contact lenses also do not help and calls for immediate attention.

Causes of blurry vision with contact lenses and solutions

Do you often find yourself squinting, rubbing or blinking your eyes to focus better, even when you have contact lenses on? If your contact lenses have suddenly made your surroundings look hazy, it could be due to several factors. You shouldn’t take blurry vision for granted because it may be a mild inconvenience today, but tomorrow, it could turn into a bigger problem. Here are some of the most common reasons why you may experience blurry vision with contact lenses:

Prescription changes

Your vision may naturally change over time. Whether it’s due to ageing, you have astigmatism, or have a progressive condition like presbyopia, your current prescription may change. If your lenses don’t match your updated prescription in terms of power and/or fitting, light rays won’t focus correctly on your retina, leading to blurry vision.

To ensure that you are always wearing an up-to-date prescription, you need to schedule regular contact lens check-ups, typically once every year or as recommended by your optician. Please note that if you’re new to contact lenses or have just got a new prescription, it might take a week or two to adjust to it. During this time, you may experience slight blurriness, but this should gradually go away.

Dry eyes

Dry eyes occur when your eyes don’t produce enough tears, or the tears evaporate too quickly. This condition can be common among contact lens wearers and can cause irritation, redness and blurred vision.

To prevent dry eyes, regular contact lens wearers swear by lubricating eye drops, or rewetting drops as they help relieve the above-mentioned mild symptoms on the go. For persistent dryness, your optician may recommend special lenses designed for dry eyes or prescribe medicated eye drops.

Allergies and irritants

Allergic reactions such as hay fever can make you tear up frequently. This makes it difficult for contact lenses to sit properly on your eyes. The preservatives in some allergy medications can also affect lens clarity, making your eyes dry and irritated.

If allergies are affecting your vision, consider talking to your optician about switching to daily disposable lenses or using anti-allergy eye drops. During peak allergy seasons, you may also need to limit lens wear and use lubricating drops to ease discomfort.

Eye infections

Blurry vision, pain, redness and discomfort in eyes are common symptoms of health hazards like conjunctivitis or pink eye.

As soon as you suspect an infection, it’s better to stop wearing your contacts immediately and consult your optician for advice, and out of hours you can visit your local A&E. You most likely will be advised a short break from contact lenses until the infection clears up and wear your prescription glasses instead.

Lens deposits and poor hygiene

Over time, protein deposits, dust and debris can accumulate on your lenses, making your vision appear cloudy. This is especially common with reusable lenses if they aren’t properly cleaned and stored.

To ensure optimum hygiene of your contacts, follow a strict lens care routine that involves the following steps:

• Always thoroughly wash and dry your hands before handling lenses.
• Use fresh contact lens solution for cleaning and storage, never water.
• Avoid wearing lenses while swimming or showering.
• Stick to your recommended wearing schedule and replace lenses, as instructed.
• If you wear monthly or two-weekly lenses, be extra diligent about cleaning them.

What to do if your contact lenses are making your vision blurry?

If you’re experiencing persistent blurriness with your contact lenses, you must visit your optician immediately. This will help you assess if there’s an underlying condition you need to treat, or simply, a prescription update. However, you can also try:

• Removing your lenses and checking if your vision improves with glasses. This can help identify if the issue is lens related.
• Cleaning or replacing your lenses if they have visible debris or if they’re past their recommended usage period.
• Using rewetting drops to relieve dryness and irritation.

By taking care of your contact lenses and staying on top of your eye health, you can enjoy clear, comfortable vision every day.
