The Importance of Eye Exams for Contact Lenses

Are you planning on wearing contact lenses for the first time? Do you need a new contact lens prescription? Are your current contacts not as comfortable as you wish they were? Your eye doctor will perform a contact lens eye exam to ensure that your vision with contacts is clear, comfortable, and safe, providing you with the right lenses for you.

What is a contact lens exam?

If you wear or want to wear contact lenses, you’ll need an eye exam for contact lenses, in addition to your regular comprehensive eye exam. Special tests are performed during a contact lens exam to evaluate your eyes and vision with contacts.

Are eyeglass prescriptions the same as contact lens prescriptions?

No, a prescription for glasses cannot be used for contact lenses. An eyeglass prescription is for lenses that are positioned approximately 12 millimeters from your eyes, whereas a contact lens prescription is measured for lenses that sit directly on the surface of your eye.

The prescription for contact lenses also includes the brand, lens diameter and curvature, which are not part of an eyeglass prescription.

Contact lenses fitting: One size does not fit all

One contact lens size doesn’t fit all eyes. If a contact lens is too flat or too steep for your corneal shape, you may experience discomfort or even eye damage. Your eye doctor will take certain measurements to determine the best contact lens design and fit for your eyes.

Corneal curvature

This measures the curvature of your eye’s clear front surface (cornea) so the eye doctor can select the optimal curve and diameter for your contact lenses. If your eye’s surface is somewhat irregular because of astigmatism or other conditions, you may require a special lens.

Pupil and iris size

The size of your pupil and iris (the colored part of your eye) is also important in determining the best contact lens design.

Tear film evaluation

This test evaluates the quality of your tears, to determine whether they will be able to keep contact lenses and your cornea sufficiently hydrated throughout the day. If you have dry eye disease, standard contact lenses may not be right for you.

Trial lenses

Following the eye exam, you will be provided with trial lenses to verify that the chosen contact lenses offer clear and comfortable vision. This will allow the eye doctor to make any fine adjustments to the prescription.

Wearing the correct contact lenses for your eyes allows you to enjoy all of the benefits of wearing contacts, while keeping your eyes healthy and comfortable.

If you’re already a contact lens wearer, visit your eye doctor at least once a year to make sure the lenses are still providing you with optimum vision and comfort.

Why You Should Avoid Online Eye Tests

An online eye exam is an automated and interactive vision test that claims to measure mainly visual acuity. It may seem like a convenient way to evaluate your vision or get an eyeglass or contact lens prescription, as these tests can be administered using your computer, tablet, or smartphone from the comfort of your home.

But these tests — which should not be confused with telehealth visits — are performed by a computer program, not a professional eye care practitioner, and they cannot and should not replace a comprehensive, in-person eye exam.

Online eye tests, which are impersonal and superficial by nature, can cause you to miss out on some important, even life-saving, information about your eye health and vision.

What Do Online Eye Tests Evaluate?

First off, it’s important to recognize that an online eye test does not evaluate the health of your eyes. It’s more of a vision test than an eye test, as it’s designed as an attempt to measure your visual acuity and refractive error, and, in some cases, contrast sensitivity and color blindness. Furthermore, the accuracy of the prescriptions provided by online vision tests is questionable. Providing the correct optical prescription requires the eye doctor’s direct and open communication with the patient. The right prescription needs subjective input and experienced analysis from an eye doctor — professional skills that can never be replicated accurately through an online program.

While the technology promises convenience, the Alberta Association of optometrists (AOA) advises caution, as these exams can offer misleading information and may contribute to a patient believing—incorrectly—that his or her eye health needs have been met. The online eye test measurements provide little-to-no information on the health of your eyes, and cannot determine whether you may have a sight-threatening condition such as cataracts, glaucoma, macular degeneration, or other eye diseases. Nor do online exams address problems like dry eye, retinal detachment, diabetic retinopathy, or functional vision problems — such as difficulty with eye teaming or convergence insufficiency.

The Importance of a Comprehensive Eye Exam

Optometrists undergo years of study and specialized training. They develop a comprehensive understanding of how to evaluate your eyes not only for sight, but for any underlying conditions. In fact, vision and health are closely linked. Comprehensive eye exams enable Dr. Aleem Bandali to detect signs of diseases that may affect your entire body, but which show early signs in your eyes.

These include:

Hypertension
High cholesterol
Diabetes
Strokes
Sjogren’s syndrome
Neurological diseases, such as multiple sclerosis (MS) or a brain tumor

Is a Virtual Eye Exam Cost-Saving?

Some people erroneously believe that an online eye test can save them not only time but also money, compared with a comprehensive eye exam performed by an optometrist or ophthalmologist. It’s important to note that these virtual tests offer only a sliver of the services you’d normally receive from your eye doctor during a thorough ocular exam.

Carrying out a professional eye exam requires training, precision, and the proper equipment. Anything less can put your eyes and vision at serious risk.

Safeguard Your Eyes and Sight

A comprehensive in-person eye exam is the only way to determine whether your eyes are healthy and free from sight-threatening conditions. Early detection and treatment of these problems can potentially prevent vision loss. Eye care practitioners frequently discover an infection, chronic illness or eye disease during what patients would have expected to be a simple, routine ocular exam. These scenarios are far more common than we’d like to imagine.

To safeguard the health of your eyes and sight, have a comprehensive, in-person eye exam with Dr. Aleem Bandali on a regular basis. Your health may depend on it.
