New tests of visual function are emerging as a result of recent technology advancements. Today, evaluation of patient populations with limited access to healthcare is made possible by diagnostic testing with portable, affordable technologies, which also allows testing outside of a clinical environment or at home. These modifications make it possible to monitor patients more actively, produce more results, and deliver fast information on the effectiveness of ongoing treatment and prospective changes in visual status. Particularly, functional vision traits such as visual acuity, contrast sensitivity, color vision, binocularity, and others can be easily assessed outside of typical clinic consultations.
