This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This research study is testing a new device called the TonoVera, which measures the pressure inside your eye. Researchers want to see how accurate and reliable this new device is compared to two other devices that doctors currently use in their offices. Eye pressure measurement is important for people with glaucoma or those at risk for it.
Measuring eye pressure accurately is critical for diagnosing and monitoring glaucoma, a serious eye condition that can lead to vision loss. This study exists to see whether the new TonoVera device works just as well as—or better than—the devices doctors use today.

You will visit the study site for one appointment where researchers will measure the pressure in your eyes using three different devices. During this visit, you'll also have a few quick vision and eye measurements taken. The study team will take multiple pressure readings from different areas of your eye with each device. The entire visit should take a couple of hours.
