Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Visual acuity is a key indicator of visual function, often measured using the ETDRS chart, the gold standard in clinical settings. However, the increasing need for accessible and cost-effective screening tools, especially in underserved areas, has led to the development of mobile health applications like the Peek Acuity application.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study aims to compare the diagnostic accuracy and efficiency of the Peek acuity application (Portable Eye Examination Kit) with the ETDRS (Early Treatment of Diabetic Retinopathy Study) chart in assessing visual acuity and refractive errors. The study will involve 58 participants, selected using a non-probability convenience sampling technique. A comparative cross-sectional design will be used.
