Bailey Lovie Chart Set

Bailey Lovie Chart Set

Precision Vision®

  • Description: The charts come as a set of two panels (21x24inches, 53x60cm) each with a high contrast chart one side and a low contrast chart (18% Weber or 10% Michelson) on the other.  The optotype set is the family of ten British Standard (1968) 5x4 non-serifed letters.  There are 14 rows with a range of sizes  from 38 to 1.9 M-units.   Sizes are given in Snellen units (in both feet and metric units), as well as visual acuity values in LogMAR and VAR (Visual Acuity Rating) for a 6 meter viewing distance. Any other viewing distance may be used as well.  A scale printed on each chart provides the score adjustment for different test distances.  With the LogMAR and VAR scales, equal credit is given for each additional letter read (each extra letter earns -0.02 with LogMAR , or 1 point with VAR)
  • Testing Distance: 6 meters (20 ft.) / Any Distance

Logarithmic SLOAN Visual Acuity Test
  • Description: Logarithmic chart uses traditional Sloan optotypes. These calibrated optotypes blur at threshold and adhere to the Snellen 5x5 grid. Sloan chart uses two smaller groups for repetitive testing and minimizes memorization. Logarithmic Sloan acuity test is a great screener for literate adults and children.
    • Notations for testing at 3 meters (10 ft.)
    • Acuity range 24M to 1.5M (20/160, 6/48 to 20/10, 6/3 equiv.)
    • Two smaller groups 6M to 1.5M for repetitive testing (20/40, 6/12 to 20/10, 6/3 equiv.)
    • Measures 23 X 35.5 cm (9 X 14 in.)
    • Fits Small Illuminator Cabinet CAT. NO. 914
    • Can be wall-mounted
    • Includes LogMar and Letter sizes on chart
    • Equivalents for 20 feet
  • Testing Distance: 3 meters (10 ft.)

SLOAN 10 Foot Translucent Distance Eye Chart
  • Description: This translucent eye chart uses Sloan optotypes for accurate testing. Each optotype has been calibrated for size, difficulty, threshold blur, and dimension. Each line is arranged equally. This eye test also includes two smaller groups for repetitive testing without memorization.
    • Notations for vision testing at 10 feet
    • Visual acuity range 10/80 to 10/8 (20160 to 20/16 equiv.)
    • Two smaller groups 10/20 to 10/8 for repetitive eyesight testing (20/40 to 20/16 equiv.)
    • Eye chart measures 23 X 35.5 cm (9 X 14 in.)
    • Fits small Illuminator Cabinet CAT. NO. 914
    • Can be wall-mounted
  • Testing Distance: 10 feet

Sloan Distance High Contrast Acuity Folding Chart
  • Description: This folding chart is a combination of many highly calibrated and accurate vision tests. It incorporates traditional Sloan optotypes for testing. This helps to establish a constant and equal acuity object from beginning to end. Also, this test uses a ETDRS format to help maintain the idea of equality during testing. Also, this folding acuity chart features two smaller groups of optotypes for repetitive non memorized testing. This acuity test provides accurate and reliable results.
    • Notations for testing at 3 meters (10 ft.)
    • Acuity range 30 M to 1.5M (20/200, 6/60 to 20/10, 6/3 equiv.)
    • Two smaller groups 7.5M to 1.5M for repetitive testing (20/50, 6/15 to 20/10, 6/3 equiv.)
    • Measures 45.5 X 45.5 cm (18 X 18 in.)
    • Can be wall-mounted
  • Testing Distance: 3 meters (10 ft.)
