Why Are My Contact Lenses Blurry? Common Causes & Quick Fixes

Updated March 5th, 2025 – Are you experiencing blurry vision with your contact lenses? Blurry contacts are a common issue for lens wearers, with multiple factors causing vision to go hazy or unclear. 

Understanding why this happens and how to prevent it can help you enjoy clear, comfortable vision every day. Read on to find out.

Is It Normal for Contacts to Be Blurry at First?

Yes, some blurriness is common for new contact lens wearers. Upon insertion, you might notice some blurry vision as the lens settles in your eye. This should only last for a second or two.

If you only recently switched to contact lenses, it may take as long as two weeks for your eyes to fully adjust to your new lenses.

What Causes Blurry Vision From Contact Lenses?

Here are five of the most common reasons you might experience blurry, hazy, or cloudy vision while wearing contact lenses:

1. Outdated prescription

Contact lens prescriptions are good for only one to two years because our vision changes as we age, especially when we reach 40. If you don’t have allergies or sensitive eyes but experience blurry vision while wearing contacts, it could be that your prescription is no longer suitable for your needs.

The only real solution is to visit an eye care professional (ECP), so they can give you an eye exam, fit you with new lenses, and update your prescription.

2. New prescription

If you had just updated your prescription and experience blurry vision, it could be that your eyes need some time to adjust to your new lenses.

It may take as long as two weeks for your eyes to get used to contact lenses, especially if you’re a new contact lens wearer.

3. Incorrect fit

Ill-fitting lenses can also cause blurry vision.

Contacts vary in diameter and thickness depending on the brand, so your eye doctor may need to fit you with different lens brands to see which works best for your eyes.

Aside from blurry vision, ill-fitting lenses can also cause eye strain and other issues, so getting the right fit is key.

4. Overwearing contact lenses

Deposits like proteins and dirt can accumulate on the surface of your contact lenses over time, even with regular cleaning. They can cause discomfort, eye irritation, and blurry vision. To avoid this, some wearers choose to stick to a monthly replacement schedule with cheaper options like Air Optix Aqua. These lenses are known for staying breathable while resisting pollen and allergen buildup.

It’s important to replace your contact lenses as scheduled. If you wear bi-weekly contacts, for example, toss them out after 14 days. If your lenses are FDA-approved for overnight wear and you wore them for several days straight, you may need to toss them out earlier than that. This applies to both bi-weekly and monthly lenses.

5. Allergies

If your eyes swell, itch, or get watery due to an allergic reaction, your contact lenses could end up not sitting properly on your eyes. This could lead to blurry vision.

Allergens like dust and pollen can stick to the surface of your lenses and trigger allergic reactions. Naturally, lenses worn daily for a month will collect allergens the whole month. This isn’t a problem with daily disposable lenses because you simply throw them away at the end of the day, allowing allergens less time to accumulate.

But if your eyes are really itchy from an allergic reaction, it may be best to refrain entirely from wearing contact lenses. Use a backup pair of glasses until your symptoms improve.

Quick Fixes For Blurry Contact Lenses 

How do you fix blurry contact lenses? If your contact lenses are suddenly blurry, it could be due to minor, temporary issues that you can resolve quickly. Here are some immediate fixes to help clear up your vision:

• Use rewetting drops if lenses feel dry.
• Clean and rinse lenses thoroughly.
• Try blinking a few times to reposition the lens.
• Gently rub your eyelids to temporarily improve your vision

If blurry vision from contacts persists, see your eye doctor immediately. They can rule out serious issues like eye infections and other problems. Many users who want consistent clarity and minimal upkeep buy Dailies Total 1 for the convenience of a fresh lens every morning.
