Hi It needs to be assessed on the job as adaptive technique may/will have been developed which maybe sufficient. Screening is there to highlight a weakness but should be very rarely used to exclude from the job without further demonstration of how the weakness plays out in the work environment.

I refer below to the following recommendation by the Keystone manufacturer in their machine manual: "However, adults whose occupations involve moving machinery or materials should (for safety reasons) score in at least the lightly shaded “Acceptable” area. This level indicates 75% stereopsis in the Shepherd-Fry Scales". Can anyone offer any further advice on the above? Thank you all so very much. ******************************** Please remove this footer before replying.
