 ====Convergence Insufficiency Symptom Survey====
-Forced response to each question is "Never", "Infrequently", "Sometimes", "Fairly Often", "Always"
   - Do your eyes feel tired when reading or doing close work?

   - Do you have to re-read the same line of words when reading?
+===Scoring===
+  - Collect response to each question from one of the 5 possible responses:
+    - "Never" = 0 points
+    - "Infrequently" = 1 point
+    - "Sometimes" = 2 points
+    - "Fairly Often" = 3 points
+    - "Always" = 4 points
+  - Tally points from each question- the total will be from 0-60 points
+===Analysis of Score===
+If score is **≥ 16** CI is likely
+  * Convergence Insufficiency mean= 30.8 ± 8.4
+  * Normal mean = 8.4 ± 6.4
+  * Cut of value of **16** gives sensitivity of 95.7% and specificity of 87.5%
