This Snellen chart includes red and green color bars for an easy and helpful color vision test Screens for Amblyopia Snellen optotypes date back to 1862, when Herman Snellen released his first eye test in England. These Snellen optotypes have changed little throughout the years and are used regularly today. These optotypes feature strong serifs and follow idea of the 5x5 grid. Snellen chart is also coupled with red and green stripes for an easy color vision test.
HOTV charts use four distinctly different yet equally recognizable letters. These letters can be identified by preliterate children, with the use of a response key. Also, featured on this HOTV vision test are both a red and a green stripe. These stripes can help as a screener for Color Vision. Also, the chart is useful for detecting early signs of amblyopia in children. This HOTV eye chart is great for school screenings for children 3-5 years old. Visual acuity range 20/100 to 20/16.
Tumbling or Illiterate "E" charts are very reliable alternative visual acuity tests. Although Landolt "C" tests are considered the standard in alternative vision tests, many studies have proven that Tumbling "E" tests are nearly equal. In fact, because of their shape, Tumbling "E"s have grating properties and have been proven to be almost better then Landolt "C"s in visual acuity establishment. Distance eye test for visual acuity screening at 20 Feet Visual Acuity range 20/100 to 20/16.
HOTV optotype are great for testing preliterate children 3-4 years old. The child must be briefly taught each optotype before testing and shown the response key included. While testing, the child must simply point to the letter that they are seeing. This takes the guessing out of pediatric vision testing and make recording more accurate. HOTV chart also includes red and green bars for quick color vision screening while testing acuity vision. Distance eye test for visual acuity screening at 20 Feet Visual Acuity range 20/100 to 20/16.
Sloan optotypes are highly calibrated to a 5x5 grid. This grid helps to create a uniform difficulty throughout the 10 optotypes. Each optotype takes up a similar space and creates a uniform blur when they are out of a patient's visual acuity range. This is an essential factor that makes Sloan optotypes so reliable and accurate in visual acuity testing. Distance Eye Chart for vision testing at 20 Feet Visual acuity range 20/100 to 20/16.
This Chart uses true Snellen optotypes for acuity vision testing. C, D, E, F, L, O, P, T optotypes feature defined serifs on each letter, making them unique to Snellen. These optotypes also fit in a 5x5 grid, also designed by Herman Snellen. This Snellen eye chart also features Snellen equivalents on the sides for accurate vision recording. This traditional Snellen chart is great for school vision screenings, as it also incorporates a red and green bar for color vision testing.

The Snellen eye chart is the familiar, classic chart of big and little letters. The chart consists of 11 lines of block letters, beginning with a large single letter on the top row. The number of letters on each row increases moving from top to bottom. The size of the letters progressively decreases, allowing for more letters on each subsequent line. Visual Acuity Test at 10 Feet distance and Equivalent to 20 Feet. Visual acuity range 20/100 to 20/16.

Traditional Snellen optotypes have changed little throughout the years, are great for school vision screenings, and are used regularly today. These optotypes feature strong serifs in the letters C, D, E, F, L, O, P, T. Two smaller groups 20/25 to 20/12.5 for repetitive eye testing.
Sloan chart uses traditional optotypes that follow a 5×5 grid idea. Sloan eye test uses logarithmic format and has equivalents on each side. They include LogMar, Decimal, 10 feet, and Meters for easy acuity recording. Two smaller groups 5M to 2M for repetitive testing (20/25, 6/7.5 to 20/10, 6/3 equiv.).

Logarithmic chart uses traditional Sloan optotypes. These calibrated optotypes 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. Includes LOGMAR and Letter sizes on chart.
This Snellen Color Alphabetical Eye Chart allows the examiner to check the Visual Acuity with Color Vision Deficiency Color Blindness simultaneously with easily understood letters and carefully selected Colors at 20 Feet distance.
Pediatric Color Eye Chart 22 x 11 made from durable PVC Sheet. The first test designed to check for color blindness while simultaneously administering visual acuity an easy, convenient way to screen for color blindness in a busy medical practice or school. This Color Vision Eye Chart is designed as a fun and affordable method for adults to easily screen children for Color vision Deficiency.
The Snellen eye chart was originally introduced in 1862 by Herman Snellen. The Snellen eye test uses the idea of a subtended 5 minutes of arc with a 20-foot distance. This became the "standard vision" measurement. Also, Snellen developed the idea of a 5x5 grid for a standard for his optotypes. Each optotype must meet certain percentage requirements in this grid before it is used for testing. This helps to make a uniform and equal vision chart. The Snellen eye chart is the basis for many other vision tests.
The Tumbling "E" vision chart is great for use with patients that are not familiar with the Roman alphabet. These patients simply must gesture the direction they see the optotype since there is only one. This optotype is place in four different directions: up, down, left, and right. The Tumbling "E" chart is considered highly reliable and accurate. It is great for the detection of Astigmatism.

The Snellen Pocket Eye Chart is a familiar widely used chart with big letters or symbols at the top and progressively smaller letters at the bottom of the chart down to 20/20 or better. This professional handy pocket-sized chart is ideal for measuring visual acuity at a distance. Perfect for optometrists, students, offices, and schools.
The Jaeger eye chart is used for reading up close and for determining your near vision. When reviewing the chart, you will see the notation 1 next to the paragraph with the smallest text and each progressive paragraph of larger text is noted with an increase in the number. As you progress to larger lettered paragraphs, the lettering size increases for lesser visual acuity. The Jaeger type scale ranges from J1 to J11 or larger, with J1 being the smallest type. J2 is considered the equivalent of 20/20 distance visual acuity at the reading distance indicated on the card (usually 12 to 14 inches from your eyes). Laminated
