“Oregon Lions Foundation will be coming to our school on Thursday, January 17, 2019, to complete vision screenings on all K-5th grade students.  If you would like your child(ren) to opt out, please notify the school office in writing prior to that date.”

There is no formal letter or form for a parent to complete.  They just need to put something in writing (handwritten note, signed email,..) stating that they do not want their child screened.
