Glasses & Contact Lens Exams

Comprehensive Eyeglass and Contact lens Exams 

At Eye Hub Optometry, we strive to meet all of your eye and vision care needs. Corrective eyeglass and lens evaluations and prescription management are provided by our optometrist in Houston. After a comprehensive eye and vision evaluation, Dr. Erin Koetter will discuss the variety of options with you to select the type or style that best fits your vision needs and lifestyle. If you suffer from dry eye, allergies, or recurring eye infections, speak with our staff to determine whether contact lenses are right for you.


Prior to prescribing contact lenses, Dr. Erin Koetter determines what level of vision correction you require. The tests your optometrist conduct depends upon your specific medical history, age, and current eye health problems. Refractive error (commonly known as nearsightedness, farsightedness, or astigmatism depending on the error) is evaluated by measuring how the eyes focus when a series of different lenses are placed in front of them. An optometrist may use either a phoropter or an automated instrument to take these measurements.

At Eye Hub, we have advanced technology to take your eye pressures without the machine that blows air into your eyes. It measures your eye's pressure, and high pressure can signify an issue like glaucoma. Other testing is possible as well.

Corrective Lenses

After determining the level of refractive error, Dr. Erin Koetter works with you to determine whether contact lenses or glasses are best for your lifestyle. If you suffer from certain conditions, such as dry eye or allergies, glasses may be the most comfortable corrective solution. Contact lenses are available in either soft or rigid gas permeable form. Contact lenses need to be changed daily, bi-weekly, or monthly, depending on what type of lens you select. Specialized contact lenses, such as bifocal contact lenses, are also available for patients with special eye conditions. 

Cosmetic Lenses

Advances in contact lens technology have created great options for cosmetic and prosthetic lenses. Custom contact lenses can be created to camouflage any color variation or irregularity and produce a natural eye color. Cosmetic lenses are also available to transform your eye color. 


After checking your eye health and visual acuity, our optician, Dr. Erin Koetter, can measure you for glasses. This process is relatively quick and consists of gathering information to fit you with the correct size.

The following are areas that must fit properly for your glasses to be comfortable:

  • Frame width - This is the horizontal portion on the front of your glasses. It's a measurement from the outer side of one corner of your frame to the other.
  • Bridge - The bridge is the small area in between each frame. It's the part of your glasses that rests on the bridge of your nose.
  • Lens height - The height of your lens is a measurement of how large your lens is vertically.
  • Temple arm - The temple arm is the part of your glasses that extends from your lenses to behind your ear.

The eyeglass fitting also consists of you choosing the desired frames and style of arms you want for your glasses. If you need help to decide, Dr. Koetter understands which frames fit what shaped-face and can assist with you with deciding. We have a wide variety to choose from, so you can find an option that you feel confident in. Once you have your new glasses, you try them on in our office. If they need any adjustments, we can perform them on the spot.
