Patients FAQ’s

The Doctors at TSO Brenham want to make sure that you receive all of the information that you need to make educated decisions about your eye health. We are always available to answer your questions.


Dr. Brandon Guillory answers frequently asked questions:

Q: Why do I need to scan my retinas/ back of the eye?

A: In considering the similarities of the human eye to a camera, the retina is the digital processor of the eye. Even with the best lenses brought to optimal focus, you will not get a good picture with a faulty processor. So with the eye, no matter how accurate your glasses or contact lenses are, vision is lost with a faulty retina. Through an examination, possibly supplemented by various means of electronic scans, many pathologies can be noticed and a plan instilled to PREVENT vision loss.

Q: Can I wear my contact lenses while I sleep?

A: Some contact lens designs are made, and have been tested, to allow sufficient oxygen through them to sufficiently nourish the cornea, even with round the clock wear. Other contact lenses are poor at allowing oxygen through them, and your eyes require a break every day. Even though some contact lens designs can be slept in by some people, others eyes may suffer. Your eye doctor should approve overnight wear. Anyone sleeping in contact lenses should have their eyes monitored closely by their eye doctor.

Q: Should I wear sunglasses during the winter?

A: It is never a bad time to protect your eyes from the harmful UV radiation from the sun. Winter activities can put us in some situations which increase our exposure to UV and visible light rays. Snow reflects those rays that would otherwise fall onto the ground. High altitude (mountain skiing) increases our exposure to the sun.

Q: At what age should my child have an eye exam?

A: Any age is a good age to have an eye exam, but it's particularly important for children entering school since seeing is a big part of learning. We see children anywhere from age 3 and up and we tailor their exam to their age and level of cooperation. School starts soon. Call us today to schedule your child's exam.
