Sloan Letter charts calibrated to test visual acuity at an intermediate distance of 66 cm (26 in.).
This chart can either be wall mounted or used in an ESV 1200 , ESV 1500 , or a Model A illuminated cabinet.
This standardized vision test is designed for amblyopia screening and testing children who have difficulties when tested with the standard near vision card.
16 inches/40 centimeters testing distance.
Some children with brain damage-related vision loss may achieve near normal results in routine vision tests (large visual field and normal or near normal visual acuity), but cannot interpret facial expressions or recognize people’s faces.
