What Do They Do in a Contact Lens Check-Up?

If you already wear contact lenses, you might wonder why your optometrist asks you to come back every year when your vision seems perfectly fine. After all, if your lenses still feel comfortable and you can see clearly, what exactly is there to check?

It is a question we hear often at Eyesight.sg. Many people assume a contact lens check-up is simply another vision test. In reality, these appointments are designed to ensure your eyes remain healthy while wearing contact lenses. Your eyes can change over time, and even a lens that once fitted perfectly may no longer be the best option.

Whether you wear daily disposable lenses for work, toric lenses for astigmatism, or Ortho-K lenses for myopia management, regular contact lens reviews help prevent small problems from becoming serious ones.

Why Are Contact Lens Check-Ups So Important?

Unlike spectacles, contact lenses sit directly on the surface of your eye for many hours every day. This means they can affect the cornea, tear film, and the amount of oxygen reaching your eyes.

Even if you have no symptoms, subtle changes can develop over time without you noticing. A routine contact lens review helps detect these changes early before they begin affecting your comfort or vision.

Regular reviews can help prevent:

• Dry eye complications
• Poor lens fitting
• Corneal irritation
• Eye infections
• Reduced oxygen supply to the cornea
• Changes in your prescription

Think of it as servicing your car. Everything may appear to be working well, but regular maintenance keeps bigger problems from developing later.

What Happens During a Contact Lens Check-Up?

A contact lens review is more detailed than many people expect. Your optometrist looks beyond your prescription to evaluate how your eyes are responding to your lenses.

1. Reviewing Your Vision

The appointment usually begins with checking your current vision while wearing your contact lenses.

Your optometrist may ask questions such as:

• Are your lenses still comfortable all day?
• Does your vision become blurry in the evening?
• Do your eyes feel dry at work?
• Have you noticed headaches or eye strain?

These answers often provide valuable clues about whether your lenses are still suitable for your lifestyle.

2. Checking Your Prescription

Although your prescription may remain stable for years, eyesight can gradually change due to age, work demands, or progression of myopia.

Your optometrist will perform a comprehensive refraction test to confirm whether your current contact lens power still provides the clearest vision possible. If required, they may recommend a slight adjustment to improve both distance and near vision.

3. Examining the Health of Your Eyes

This is one of the most important parts of the appointment. Using a slit lamp microscope, your optometrist carefully examines:

• Your cornea
• Eyelids
• Conjunctiva
• Tear film
• Blood vessels
• Surface of the eye

They look for signs of dryness, allergies, scratches, inflammation, protein deposits, or reduced oxygen supply. Many of these issues develop gradually and may not cause symptoms in the early stages.

4. Assessing the Contact Lens Fit

A contact lens should move slightly every time you blink. If it fits too tightly, oxygen cannot reach the cornea effectively. If it is too loose, it may move excessively, causing blurred vision and discomfort.

During your review, your optometrist checks:

• Lens position
• Lens movement
• Lens stability
• Centration
• Overall comfort

Even tiny adjustments in lens design can significantly improve comfort.

5. Evaluating Your Tear Film

Singapore's warm weather is often balanced by long hours in air-conditioned offices, shopping centres, schools, and public transport. This environment commonly contributes to dry eye symptoms.

Your optometrist will assess tear quantity, quality, stability, and signs of evaporation. If dryness is becoming an issue, they may recommend:

• Daily disposable contact lenses
• More breathable lens materials
• Lubricating eye drops
• Changes to wearing time

Small changes often make wearing contact lenses much more comfortable.

6. Checking for Lens Deposits

Over time, contact lenses naturally collect protein deposits, oils, cosmetics, dust, and environmental particles. Even if lenses appear clean, microscopic deposits can affect comfort and increase the risk of infection.

If your current cleaning routine is not removing these deposits effectively, your optometrist may suggest a different cleaning solution or a new replacement schedule.

7. Reviewing Your Lens Care Routine

One of the biggest causes of eye infections is poor hygiene rather than the lenses themselves. During your appointment, your optometrist may ask about:

• How often you replace your lenses
• Whether you sleep in them
• How you clean them
• How frequently you replace your storage case
• Whether you wash and dry your hands before handling lenses

Many people unknowingly develop habits that increase their risk of infection. A quick review of your contact lens hygiene routine can help keep your eyes safe.

Monitoring Children Wearing Contact Lenses

Children wearing contact lenses for myopia management require more detailed reviews. For treatments such as MiSight lenses or Ortho-K, appointments often include monitoring:

• Eye growth
• Changes in prescription
• Lens fit
• Corneal health
• Treatment effectiveness

These reviews allow adjustments to be made as children continue growing, helping to manage the progression of short-sightedness more effectively.

Should You Bring Your Contact Lenses to the Appointment?

Yes.

If you normally wear soft contact lenses, your optometrist will often ask you to attend while wearing them. This allows them to evaluate how the lenses fit during normal daily use.

If you wear Ortho-K lenses overnight, you may also be asked to bring the lenses themselves so they can be inspected for scratches, deposits, or damage.

How Often Should You Have a Contact Lens Check-Up?

For most people, an annual contact lens review is recommended. However, more frequent appointments may be advised if you:

• Wear Ortho-K lenses
• Are using myopia management lenses
• Have dry eye disease
• Recently changed lens type
• Experience discomfort or blurred vision
• Have a history of eye infections

Regular reviews help ensure your lenses continue to meet your changing visual needs.

When Should You Book an Appointment Sooner?

Do not wait until your annual review if you notice:

• Persistent redness
• Pain
• Sudden blurred vision
• Light sensitivity
• Excessive tearing or discharge
• A lens that no longer feels comfortable

These symptoms should always be assessed promptly through a comprehensive eye examination to prevent more serious complications.

Frequently Asked Questions

Q: Do I need a contact lens check-up if my eyesight has not changed?

A: Yes. The appointment is mainly about checking the health of your eyes and ensuring your lenses continue to fit safely, not just updating your prescription.

Q: Can I order contact lenses online without having a review?

A: It is not recommended. Even if your prescription appears unchanged, your eye health and lens fit may have altered since your last examination.

Q: How long does a contact lens check-up take?

A: Most appointments take between 20 and 40 minutes, depending on whether additional assessments or prescription changes are needed.

Q: Will my optometrist change my lens brand?

A: Only if there is a clinical reason to do so, such as improving comfort, vision, oxygen transmission, or managing dry eyes.

Q: Are contact lens reviews necessary for daily disposable lenses?

A: Yes. Although daily disposable lenses reduce the risk of deposits and infections, your eye health and lens fit should still be reviewed regularly.
