Contact Lens Exams: What to Expect and Why They're Important

Contact lenses are a popular alternative to glasses, offering a clear field of vision and more freedom for active lifestyles. As part of optometry, contact lens exams are designed to ensure that your lenses are the right fit for you, both in terms of your eye health and your lifestyle. That's why it's crucial to understand the process and importance of these exams.

What is a Contact Lens Exam?

A contact lens exam is designed to measure your eye's surface to ensure the right fit for your contact lenses. It also involves assessing the health of your eyes to ensure that wearing contact lenses won't adversely affect your vision or eye health.

During the exam, the optometrist will measure your eye's curvature, diameter, and other essential aspects to determine the right size and type of contact lens for you. These detailed measurements help ensure that your lenses will fit comfortably and provide clear vision. The optometrist will also assess the moisture level of your eyes, as dry eyes can often make wearing contacts uncomfortable.

A significant part of the contact lens exam involves checking the overall health of your eyes. The optometrist will look for any indications of eye conditions or diseases that might make you unsuitable for contact lens wear, or that may require special types of lenses.

Preparing for Your First Contact Lens Exam

Before your appointment, make sure to note any vision problems you've been experiencing, even if they seem minor. This could include issues like blurriness, difficulty seeing at night, or discomfort when reading or using a computer.

It's also essential to gather information about your medical history. The optometrist will want to know about any eye diseases in your family, as well as any general health conditions you have, including allergies. These can affect both your suitability for contact lenses and the type of lenses recommended for you.

If you're switching from glasses to contacts, bring your current prescription with you. This can serve as a starting point for determining your contact lens prescription. Remember, a glasses prescription is not the same as a contact lens prescription, as the lenses sit directly on your eye, requiring different measurements.

What to Expect During

Preliminary Vision Check: The optometrist will start with a vision test to check your visual acuity. This is typically done using a standard eye chart.

1. Corneal Measurements: Using a device called a keratometer, the optometrist will measure the curvature of your cornea. This helps in determining the right fit for your contact lenses.

2. Pupil and Iris Measurements: The size of your pupil and iris (the colored part of your eye) will also be measured. These measurements help ensure that the lenses will cover your cornea properly.

3. Evaluation of Tear Film: Your optometrist will assess the moisture level of your eyes, as contact lenses can dry out your eyes.

4. Contact Lens Fitting: Based on all these measurements and evaluations, the optometrist will recommend a type and brand of contact lens that is most suitable for you. You'll typically be given a pair of trial lenses to ensure they fit well and feel comfortable.

What Are the Next Steps?

After your contact lens exam, it's essential to follow your optometrist's advice and instructions. This includes how to care for your lenses and your eyes, how often to replace your lenses, and when to come in for your next exam.

If you've been given trial lenses, wear them for the recommended period, noting any discomfort or vision issues. If everything feels and looks good, then you're all set. If not, contact your optometrist to discuss the problems you're experiencing.

Taking care of your contact lenses is crucial for maintaining your eye health. Always wash your hands before handling your lenses, and clean and store them as instructed by your optometrist.

When Should You Schedule Your Next Appointment?

The frequency of your contact lens exams will depend on several factors, including your eye health, how well you tolerate your contact lenses, and your optometrist's recommendations. However, as a general rule, you should have a contact lens exam at least once a year.

If you experience changes in your vision or discomfort with your lenses, don't wait for your annual exam. Contact your optometrist to discuss your symptoms and decide if you need to be seen sooner.
