Whether you’re thinking about switching from glasses to contact lenses, already wear contact lenses and require a check-up or are completely new to vision correction and considering wearing contact lenses, this guide will help answer all your questions. Let’s learn what happens during an eye test for contact lenses, why it’s important and how often you need it.
What is a vision test for contact lenses?
A vision test for contact lenses is an eye exam designed for people who wear or plan to wear contact lenses. It ensures that the contact lenses are safe, comfortable and suited to the shape and needs of your eyes. While the basic eye exam is the same for both glasses and lenses, the contact lens test includes some additional steps on top of the standard eye test.
Why is a contact lens eye test important?
Poorly fitted lenses can lead to blurry vision, discomfort and even permanent vision issues. A contact lens appointment is essential, not just for first-time wearers, but also for those who already use contact lenses. The assessment ensures:
- You’re using the correct prescription
- Any underlying eye conditions such as dry eyes or astigmatism are detected
- Your contact lenses fit your eyes properly
Additionally, during the fitting session, you will learn how to insert and remove your lenses comfortably and safely.
What happens during an eye test for contact lenses?
During your contact lens eye exam, your optician will check your vision and eye health to determine the most suitable type of contact lenses for you, based on your eye health and lifestyle. Once the fitting is complete, your optician will provide you with an up-to-date contact lens prescription.
The process for an eye test for contact lenses includes:
1. Discussion with your optician
Your optician will ask you about your daily routine, such as your screen time, physical activities and more to determine if daily disposables, monthly lenses or extended-wear contacts are suitable for you.
2. Measurements
Several measurements are taken to ensure that the contact lenses fit properly and feel comfortable. The measurements include:
- Measuring corneal curvature using a keratometer or corneal topographer to assess the shape of your cornea to help choose the right lens size and fit.
- Checking the pupil and iris size to ensure optimum lens alignment.
- Assessing tear film stability with tests like the Schirmer’s test or tear break-up time to check for dry eyes.
3. Lens fitting
During this stage, you will try some trial lenses to see how they sit and move on your eyes which your optician will examine using a slit lamp. Consequently, your optician will also guide you on how to insert, remove and clean your lenses safely.
4. Follow-up appointment
Follow-up appointments are essential for maintaining your eye health. They generally involve examining your cornea and overall eye health to detect any changes or complications caused by the contact lenses.
Skipping a contact lens fitting just isn’t worth the risk. A proper assessment ensures your lenses are safe, comfortable and effective for long-term wear. Whether you’re new to lenses or changing types, it’s the key to maintaining healthy vision, says Tina Patel, Contact Lens Optician at Feel Good Contacts.
How often should you get a vision test for contact lenses?
Your optician will recommend how often you need a contact lens aftercare, based on your eye health, the lenses you wear and your wearing pattern. Some people need check-ups more often than others. Regular visits help keep your eyes healthy and your lenses working well.
Can you buy contact lenses without a vision test?
No. You cannot buy contact lenses without a vision test and a valid copy of your contact lens prescription from your optician. This is because using contact lenses without following the correct process could cause your eyes more harm than good. Although some online retailers do not require proof, you should still not skip the essential steps.
Where can you get a contact lens eye test in the UK?
Contact lens eye tests and fitting appointments are widely available at high street opticians and independent eye clinics.
Did you know that the NHS offers free eye tests to eligible individuals, including children and those with certain medical conditions?
Frequently Asked Questions
Do I need a different eye test for contact lenses than for glasses?
Yes, contact lens examinations include additional tests such as corneal measurements and tear film checks to ensure your lenses fit safely and comfortably. Also, the power of your contact lenses is often different to the power of your glasses. This is because contact lenses sit directly on your eye and glasses sit slightly further away.
How long does a contact lens eye test take?
Usually, a vision test for contact lenses takes around 60 to 90 minutes, including the lens fitting session and instructions regarding wear and care for your lenses.
Can I get a contact lens prescription online?
No, you cannot get a contact lens prescription online. You must visit an optician to get an eye examination and contact lens fitting to receive a copy of your prescription.
What should I bring to my contact lens eye test?
While getting the vision test for contact lenses, you should carry:
1. Your current glasses (if any).
2. Your old prescription (if available).
3. List of any eye-related symptoms or issues (if you have any).
Is a vision test for contact lenses painful or uncomfortable?
No, a vision test for contact lenses should usually be pain free, especially if you are being fitted by a qualified optician. You might feel mild discomfort during some of the tests or when the lenses are inserted for the first time, but this is only temporary and should feel manageable.
