It is very important to check and record your child’s vision prior to your Virtual Visit.  The vision must be checked in each eye, right and left. If your child wears glasses, please make sure they are used during the test.


Print a Full-Size Visual Acuity Chart

  • If your child knows their letters or is older than 6 - use the Snellen Chart found at

  • If your child is under 6 or they do not know their letters - use HOTV Matching Chart found at


Setting Up the Testing Area

  • You will need a space that is at least 12 to15 feet long.

  • Tape Snellen Chart on the wall at eye level, when seated.

  • Place a chair facing the eye chart, where the back of the chair measures 10 feet from the wall where the Snellen Chart is taped.

  • Ways to measure 10 feet:

    • Tape measure

    • “Measure” app on iOS or Android

    • Lay 11 pages of printer paper (8.5”x11”) end to end



Checking Your Child’s Vision - GENERAL GUIDELINES:

  • It is best to do the test in the days before your Virtual Visit and not on the day of the visit.

  • If your child wears glasses, make sure they are on.

  • Practice first and do not offer any hints!

  • Test your child’s RIGHT eye first by patching or covering their left eye - make sure there is no peeking or cheating!

  • Once you have checked the vision in their right eye, switch the patch or covering to their right eye and check the LEFT eye.

Checking Your Child's Vision - Snellen Chart

  • With your child seated 10 feet away from the eye chart on the wall, ask them to read the lowest line of letters they can with each eye.

  • They must be able to read at least half of the letters to count.  Record this number as 20/____. Also record how reliable you think the results are.


Checking Your Child's Vision - HOTV Matching Chart

  • For the HOTV Matching Chart, it is best to practice “the game” at a closer distance before starting the test.

  • For a video demonstrating the HOTV Matching Chart, please click here.

  • When ready, stand 10 feet from your child (use measuring methods above).

  • Start with the top letter on one side of the column, ask your child to match the letter to their matching guide.

  • If they identify the letter correctly, move on to the next smaller letter.

  • If they cannot identify the letter, spin the column to another side, go up a letter in size and continue testing as above.

  • Your child must identify 3 out of 4 letters correctly to count.  Record this number as 20/_____. Also record how reliable you think the results are.


Record your results in a manner similar to below:
