Contact Lens Examinations

man removing contact2For many people, contact lenses provide greater convenience and more satisfying vision correction than eyeglasses.

Here’s what’s involved in a diagnostic contact lens exam for a patient trying contact lenses on for the first time.

A medical eye examination comes first

Before contact lenses are prescribed, a medical eye examination is performed. During this examination, your doctor determines if your eyes are healthy enough to begin wearing contact lenses. If your eyes are healthy enough, the next step is a diagnostic contact lens examination.

Diagnostic contact lens examination

Prescribing contact lenses involves a consideration of your lifestyle and your preferences regarding contact lenses. For example, you might want to change your eye color with tinted contact lenses. Other patients are more interested in convenient options such as daily disposables or overnight wear. Although most patients choose soft contact lenses, the advantages and disadvantages of rigid gas permeable contact lenses will be discussed.

If you are over age 40 and need bifocals, modern multifocal and bifocal contact lenses are available.

Corneal curvature vs. contact lens curvature

Just as one shoe size doesn’t fit all feet, one contact lens curvature doesn’t fit all corneas. If the curvature of a contact lens is too flat or too steep for your cornea’s shape, you may experience discomfort or even damage to your eye. Measurements will be taken to determine the best contact lens curvature, size and design for your eyes.

Diagnostic contact lenses

In most cases, diagnostic contact lenses will be used to help determine the prescription. Lenses will be placed on your eye and your doctor will use a biomicroscope to evaluate the position and movement of the lenses as you blink and look in different directions. You will also be asked how the lenses feel.

For patient new to contact lenses, good comfort is usually achieved in about 15 minutes. When your diagnostic lenses provide good comfort and clear vision, you will be given instructions on how to care for your lenses and how long to wear them. You will also receive training on how to handle, apply and remove contact lenses.

Follow-up examinations to maintain good eye health

Your contact lens treatment program might involve a number of follow-up examinations so your doctor can confirm the lenses are maintaining good eye health. Often, your doctor will be able to see signs of contact lens-related complications before you are aware of a problem. If abnormal signs are present during your follow-up examinations, your doctor may modify the initial contact lens prescription by trying a different lens or lens material, using a different lens care method, or adjusting your contact lens wearing time.

Your contact lens prescription

After confirming that a particular contact lens provides good comfort and vision, your doctor will then be able to write a final contact lens prescription for you. This prescription will designate the contact lens power, the curvature of the lens, the lens diameter, and the lens name and manufacturer.

Regular contact lens examinations

Regardless of how often or how long you wear your contact lenses, your eyes should be examined on a regular basis to make sure your that you are not developing any contact lens-induced complications.




Dear Patients and Families of First Eye Care Grand Prairie,

In light of the recent development and spread of COVID-19, our top priority has remained the safety of our patients, families, community, and staff.

The American Optometric Association (AOA), Texas Optometric Association (TOA), and the Centers for Disease Control and Prevention (CDC) have recommended that “health care facilities and clinicians should prioritize urgent and emergency visits and procedures now and for the coming several weeks” and to “postpone routine dental and eyecare visits.

To better follow the guidelines recommended by the CDC, we have made the decision to postpone routine eye exams and temporarily close. A doctor will be on call for urgent or emergency medical eye visits only. Should you have an ocular emergency that requires immediate or urgent care, whether it is an injury, infection, foreign body, or sudden change in vision, please call/text (469) 563-2460.

We will have limited staff in the office on an as needed basis for urgent/emergency visits, and to take care of contact lens orders, picking up glasses, etc. Patients can arrange to get their contact lenses ordered and shipped to home, or curbside pick up of glasses/contact lenses can also be arranged. We believe that this unfortunate but necessary step will allow us to better follow the CDC’s guidelines and the Dallas County Shelter in Place Order to help limit the spread of COVID-19.

We will continue to monitor and keep you informed as the situation unfolds and will update you on changing hours as we learn more.

We want to thank you for your overwhelming understanding and support as we get through these difficult times together (but socially distant). We are most concerned for your health and safety, and that of your family, and look forward to seeing you again soon!
