About this trial

The goal of this observational study is to assess the reliability and validity of the 9-object MLSDT for evaluation of participants with moderate to severe vision impairment when tested without a wearable low-vision magnifying aid (eGlasses) and then with eGlasses. These results will be compared to ETDRS testing results for the same participants without eGlasses and then with eGlasses. Two cohorts will consist of participants who have vision loss due to STGD or geographic atrophy (GA) due to age-related macular degenerations (AMD). Normally sighted participants will provide a control group.
