Linear Spaced Translucent Sloan Vision Chart
Two smaller groups 10/25 to 20/8 for repetitive eyesight testing (20/50 to 20/16 equiv.).
Can be wall-mounted.
Sloan
optotype
s were developed by Louise Sloan in 1959. She developed a set of 10
optotype
s that had the same basis as the Snellen
optotype
s, the 5×5 grid. However, Sloan
optotype
s do not use serifs and use a geometric progression. This Sloan chart still uses Snellen equivalents and is calibrated for testing at 10 feet.

Logarithmic SLOAN Visual Acuity Test
Two smaller groups 6M to 1.5M for repetitive testing (20/40, 6/12 to 20/10, 6/3 equiv.).
Can be wall-mounted.
Includes LogMar and Letter sizes on chart.
Logarithmic chart uses traditional Sloan
optotype
- These calibrated
optotype
s blur at threshold and adhere to the Snellen 5×5 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.

Tumbling E Visual Acuity Color Vision Screening
Red and Green color bars for an easy and helpful place to start administering the test.
Tumbling or Illiterate E charts have one of the best visual acuity thresholds among alternate symbol acuity tests. Tumbling E tests are considered comparable to Landolt C tests which are considered the basis of alternate symbol tests. Great for the detection of Astigmatism.

Traditional Tumbling E Visual Acuity Chart
Can be wall-mounted.
Traditional design.
Great for vision screening in multiple languages.
Helpful 20 foot equivalents.
The Tumbling E test uses a single
optotype
, the E in four different positions; up, down, left and right. By using a single symbol
optotype
, this eye test can be administered to several different groups of people, including children, illiterate adults, non-speaking adults, and patients not familiar with the Roman alphabet. The patient will only have to signal which direction the E is facing.
