Abstract
The present invention is a tear production measuring sheet that has a pair of measuring strips adapted to be used for the right and left eyes and is disposed side by side in such a manner that the strips have a common scale. Each of the measuring strips is separated from the measuring sheet by a cut formed in the measuring sheet so as to extend around the measuring strip, except for a connection between the measuring strip and the sheet.
