Scoring: Each item receives points as follows:

No difficulty: 4 points

A little difficulty: 3 points

A moderate amount: 2 points

A great deal: 1 point

Unable to do: 0 points.

Do not score items if patients don't participate in the activity for a non-vision-related reason. (For example, they had never taken part in sports.)

Total the scores and divide by the number of applicable questions for a resulting average between 0 and 4. Multiply the average by 25. The range now is from 0 (vision prevents patient from doing all activities) and 100 (patient can do all activities without difficulty).
