Building a Database of Results From People Without Eye Problems

Completed

Conditions studied: Glaucoma

In brief

The purpose of this study is to build a database of results from a new test that measures contrast sensitivity (the Spaeth-Richman Contrast Sensitivity Test (SPARCS)). Contrast sensitivity is an important part of your ability to see. When contrast sensitivity decreases, you are less able to see objects and detect motion. For instance, if you have decreased contrast sensitivity, you might be less able to read, see in the dark, drive, hit a ball, or walk safely. Decrease in contrast sensitivity leads to a decrease in quality of life.
