The Leading Optometrist in Downtown

The eye care professionals of Downtown TSO, specialize in understanding how the human eye really works, as well as diseases and conditions that affect your vision—many of which do not always have obvious symptoms. The eye doctor of Downtown TSO, located in downtown Houston, knows how age and risk factors affect vision over time for young and old, and understands the benefits and features of corrective lenses, both as eyeglass lenses and contact lenses.

Meet Your Local Downtown Houston Eye Doctor:

At Downtown TSO, our optometrist will take the time to explain the results of your eye exam, describe your options and listen to your eye care needs. Because maintaining good eye health is an ongoing partnership, our eye doctors encourage you to ask questions and share your health information, which could be vital to monitoring, diagnosing and treating potential vision problems.
