Description
This LogMAR Distance Vision Chart is a professional-grade diagnostic tool designed for high-accuracy visual acuity testing. Unlike traditional Snellen charts, this logarithmic chart uses the ETDRS-style layout, providing equal spacing between letters and rows to ensure consistent task difficulty across all testing levels.
Designed specifically for 3-meter (10-foot) testing distances, this chart is an essential asset for ophthalmologists, optometrists, and vision screening camps where precision and portability are paramount.
Key Features
-
LogMAR Precision: Features a standardized logarithmic progression of optotypes, offering more sensitive and reliable measurements of visual acuity compared to standard charts.
-
Optotype Consistency: Uses high-contrast, bold slab-serif alphabets (Sloan letters) that are equally legible, reducing “guessing” bias.
-
Dual-Notation Scale: Includes multiple scoring notations for convenience:
-
Metric (3m) & Imperial (10ft) ratios.
-
Decimal values.
-
LogMAR scores (ranging from 1.0 to 0.0).
-
-
Portable & Foldable Design: The chart is frame-mounted and engineered with a foldable hinge, making it incredibly easy to carry for mobile eye clinics, school screenings, or home visits.
-
Durable Build: Printed on high-quality, non-reflective material to prevent glare and ensure longevity under clinical lighting.
-
Comprehensive Range: Covers a wide spectrum of vision levels, from 3/30 (10/100) down to a crisp 3/3 (10/10) LogMAR 0.0.
