At last you can replace your old Kindergarten acrylic chart with an accurate LogMAR Kay Picture vision Test, with Snellen sizing. We have teamed up with Evans Instruments to provide our Kay Picture Screening Chart to fit a standard illuminated cabinet or drum.
The Kay Picture Test Vision Screening Acrylic Chart measures LogMAR visual acuity at three metres distance. It measures visual acuity sizes from LogMAR 0.80 to -0.10 (Snellen 3/19 – 3/2.4) with sizes 0.3 to -0.1 having a central linear format. It fits a standard large Evans illuminated LED light box and four-sided rotating test type.
