Health Watch - Technology: Vision Quest

Health Watch is a Public Service of the Office of News and Publications and is intended to provide general information only and should not replace the advice of a medical professional. You should contact your physician if you have questions about any of these topics.


This week on Health Watch, we’ve been talking about how technology can help improve patients’ lives. Robot surgeons make surgery easier, devices help keep hearts and lungs working, and technology can even help people hear. But not all helpful technology is medical technology.

Many of the devices used for everyday life have features that are helpful to people with impaired vision. Dr. Yu-Guang He, an ophthalmologist at UT Southwestern Medical Center, says many devices like electronic readers or smart phones allow users to adjust the font size or contrast to make reading easier or even convert text to speech and read out loud. GPS devices or cell phone navigational applications often offer verbalized instructions, and there are voice-activated phones that allow users to speak a name to make a call. If you find yourself having to adjust font or contrast to read, you should make an appointment with your eye doctor.
