Basic objectives2 - Others

Intervention: Interventions/Control_1 - Within a single session, monocular visual acuity is measured for the study eye under five visual conditions (including a baseline condition), using both the conventional method (with the other eye occluded) and a new method (presenting the target to only one eye while both eyes remain open). Each measurement takes approximately several tens of seconds, with an interval of several tens of seconds between measurements. The intervention consists of a single session on a single day.

Eligibility: Age-lower limit - 18 years-old <= Age-upper limit - Not applicable Gender - Male and Female Key inclusion criteria - Individuals aged 18 years or older at the time of consent, with corrected visual acuity of 1.0 (logMAR 0.0) or better in both eyes on prior standard testing, who are able to understand the study and provide free and voluntary written informed consent. Key exclusion criteria - Individuals who do not meet the inclusion criteria above, or whom the attending physician or principal investigator judges unsuitable for participation on medical grounds.
