If you wear contact lenses every day, it’s easy to lose track of how long you’ve been using your current pair. However, wearing lenses beyond their recommended lifespan can put your eye health at risk. Contact lenses are designed to be replaced on a specific schedule and using them too long can lead to discomfort, infection, and changes in vision quality. Here are some key signs it’s time to replace your contact lenses.
 

Your Eyes Feel Dry or Irritated

If your lenses begin to feel dry, scratchy, or uncomfortable (even with proper cleaning) it may be a sign that the lenses are breaking down. Over time, proteins and debris build up on the lens surface, reducing oxygen flow to your eyes. Replacing your lenses as directed helps maintain comfort and protect against irritation.
 

Your Vision Seems Blurry

Blurry vision can indicate that your lenses have warped or accumulated deposits that interfere with clarity. If cleaning doesn’t improve your vision, it’s best to switch to a fresh pair and schedule a contact lens exam to ensure your prescription is still accurate.
 

You Notice Redness or Sensitivity

Persistent redness, burning, or light sensitivity are signs that your eyes are under stress - often due to overwearing your lenses. Old or damaged contacts can trap bacteria or reduce oxygen, increasing your risk of infection. Don’t ignore these symptoms—remove your lenses immediately and consult your optometrist.
 

Your Replacement Schedule Has Slipped

Many wearers unintentionally stretch out their replacement schedule, especially with bi-weekly or monthly lenses. Even if your lenses feel fine, using them past their expiration period increases the chance of buildup and irritation. Mark your replacement dates in your calendar or set reminders to stay consistent.
 

You Haven’t Had a Contact Lens Exam in a Year

Even if your lenses feel comfortable, your eyes and prescription can change over time. An annual contact lens exam and fitting allows your optometrist to evaluate your eye health, ensure your lenses still fit properly, and recommend new materials or brands for better comfort and vision.
 

Time for a New Pair of Contacts?

Wearing contact lenses should always be comfortable and clear - never irritating or blurry. Paying attention to how your eyes feel and sticking to your replacement schedule are essential for maintaining healthy vision. If you’re unsure whether your lenses are still the right fit, it’s time for an update.
