Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
I believe the test is called visual acuity. It measures the clarity of a patient's vision. Your granddaughter would not be able to do this eye test. It is performed by having the patient sit a certain distance from an eye chart that is on the wall. While covering one eye at a time, the child reads from left to right all of the letters or symbols on one line. Then reads all of the letters or symbols on the line below the top line. The letters and symbols on the second line are smaller than those on the top line. Continuing down the chart until the child can no longer read the letters or symbols on a line. On the left side of each line is the child's visual acuity indicated by two numbers: 20/20 is normal, 20/30, 20/40, etc. A visual acuity of 20/50 means that the child's vision(in one eye) from 20 foot away from an object is as clear as a child with normal vision seeing the same object from 50 feet away. The results of a visual acuity test has two results, one for each eye. For example, a patient having results of a visual acuity test of 20/20(right eye) and 20/20(left eye) has normal vision in both eyes. This test requires cooperation from the patient. From your description, it seems as if she is getting excellent care. Please return if we can assist you again.
