“The entire experience was so very easy and I absolutely loved my doctor. She was helpful, informative and had such fantastic energy! I had no idea that my adult daughter was also a patient. Will most definitely be returning.”
Audra H.January 15, 2026
“I’ve seen Dr. Bui for the past 2-3 years now and I haven’t been disappointed. When I arrived to my appointment, I was greeted by the office staff, and after completing my patient intake forms I was immediately taken in the back to begin my exam. Dr. Bui will explain everything that’s going on with your eyes in a manner in which you can understand. I was literally seen at a different location than my normal location just to see Dr. Bui. I have every intention on going back next year.

About Dr. Sandra Bui
Sandra Bui, O.D., received her Doctor of Optometry from the University of Houston's College of Optometry in 2019 and earned her Bachelor of Science in Biomedical Sciences from Texas A&M University. She has held numerous leadership positions in the American Optometric Student Association, the National Optometric Student Association, and the Optometric Practice Management Association.
Dr. Bui has received various awards and recognitions and is a member of the American Optometric Association, the Texas Optometric Association, the National Optometric Association, and the Harris County Optometric Society. She is a licensed Therapeutic Optometrist and Optometric Glaucoma Specialist.
Dr. Bui's interest in optometry began as a young girl. When she was 7 years old, her parents noticed she was sitting very close to the TV, and they took her to an optometrist. After receiving her first pair of glasses, her world was no longer a big, blurry place anymore, and she began to overcome her shyness and became noticeably more comfortable talking to people.
In practice since 2019, Dr. Bui loves improving her patients' quality of life by enhancing their overall ocular health and vision. She also loves to socialize, and optometry gives her the opportunity to interact with unique individuals every day.
Outside of the office, Dr. Bui enjoys spending time with family and friends, exploring new restaurants, traveling, and singing karaoke. She is happily married to her high school sweetheart, and they share their home with a Great Dane fur baby.

Dr. Bui was awesome, she clearly knows her stuff, and I like the way she patiently took my history and took the time to get my needs met.
She is the consummate professional.
Also, the lady who helped me select frames, handled my insurance and fitted me for the glasses was kind and thorough.
I will certainly recommend friends and colleagues to Dr. Bui and staff.
