Accommodation flexibility chart numbers/letters (2 charts)

The accommodation flexibility charts come with numbers and letters (2 separate charts). They are made to train the accomodation flexibility. The large chart is placed on the wall (3m distance) and the small chart is held in the hand. Ask the patient to read one letter or number from the distance chart, then one from the near chart, and so on. Measure the number of intervals per minute. Great for sportsvision!
