The North Austin Optometrist

At Texas State Optical, our eye care professionals specialize in understanding how the human eye really works, as well as studying diseases and conditions that affect your vision—many of which do not always have obvious symptoms. Eye doctors know how age and risk factors affect vision over time for young and old, and they understand the benefits and features of corrective lenses, both as eyeglass lenses and contact lenses.

Meet Your North Austin Eye Doctors:

Our TSO Capital optometrists take the time to explain the results of your eye care service, describe your options and listen to your eye care needs. Because maintaining good eye health is an ongoing partnership, we encourage you to ask questions and share your health information, which could be vital to monitoring, diagnosing and treating potential vision problems.
