Description

Brand ASF

The ASF Logmar Led English Chart is a specialized vision chart engineered for precise visual acuity assessment in ophthalmology. It is primarily utilized in hospital and clinic settings to accurately measure a patient’s visual acuity. This chart employs the LogMAR (Logarithm of the Minimum Angle of Resolution) system, which is widely recognized for providing more accurate and standardized acuity measurements compared to conventional charts.

Constructed from durable metal, the ASF Logmar Led English Chart features LED illumination, ensuring consistent and clear presentation of English alphabet optotypes. The chart is designed in a square shape and operates manually.

The chart’s design facilitates LogMAR scoring, where letter sizes change in precise 0.1 LogMAR units from one row to the next. It displays letters ranging from 0.80 LogMAR (largest) to -0.30 LogMAR (smallest), allowing clinicians to record the LogMAR size of the smallest letters a patient can read.
