Frequently Asked Questions

• What can a Snellen eye chart do for You?

  Home use of this Snellen eye chart will help you determine the clarity of your distance vision. This can be useful to screen children for nearsightedness, which causes blurry distance vision. The chart also can help you determine if you meet the legal visual acuity requirement for a valid driver’s license (20/40 in most states).

• What should my vision be on an eye chart?

  Eye charts can be configured in various ways. Generally, if you can read the big "E" at the top of the chart, but none of the letters lower than that, your vision is considered 20/200. 20/200 vision means that you can read a letter at 20 feet that people with "normal" vision could read at 200 feet. This means that your visual acuity is very poor.

• How is an e chart used to test visual acuity?

  The optician asks the person being tested to use either hand (with their fingers extended) to show which direction the "fingers" of the E are pointing: right, left, up or down. Studies have shown that visual acuity measurements using a tumbling E chart are virtually the same as those obtained from testing with a standard Snellen eye chart.

• How many eye groups are there for Snellen vision testing?

  Two smaller groups 20/25 to 20/12.5 for repetitive eye testing. Can be wall-mounted. Sloan optotypes used. Two smaller groups 20/25 to 20/12.5 for repetitive eye testing. Can be wall-mounted.
