VISION SCREENER VISION SCREENING COMPETENCIES: MYOPIA (DISTANT VISION) AND HYPEROPIA (NEAR VISION) USING PHOTO VISION SCREENER
Essential Steps for Accurate Measurement
COMPETENCY | KEY POINTS AND PRECAUTIONS |
1. Charge up device fully before use. | Refer to user manual or instructions on device website |
2. Turn device power to on. | |
3. Use in an environment with subdued lighting. | Close blinds or drapes and turn off lighting in the room where screening will take place. The room does not need to be completely dark. |
4. Set up screening approximately 3 feet from the student. | Student should be seated comfortably. Students may sit on a parent or caregiver's lap. Students do not need to remove eyeglasses for the screening. Students in wheelchairs can remain in their wheelchair. |
5. Select specific student if students' names have been pre-entered into the devise. Otherwise, have a roster with student's names to record the results. | See user manual for all options available on the photo vision screening devise. Date of birth may be a required entry or student's age range may be selected. |
6. To start the screening, select go on the device. | |
7. Stand with one foot ahead of the other. Slowly rotate the devise upward. Locate both of student's eyes on the screen and keep the devise on a level plane with the student's eyes. | Ask student to look at the device. The device may have flashing lights or make a sound to attract student's attention. |
8. Slightly lean forward or backward to get the appropriate distance for the device. When no distance warnings are on the screen, you are in the proper distance range to do the screening. | The screen should indicate if you are too close or too far from the subject. |
9. When the screen indicates the screening is being captured, hold the device steady until the results appear. | The capture is less than 1 second. If you are unable to capture the student's pupils, the measurement will be stopped. At this point you can retry the screening. A common reason that the screening was not successful, is that the student's pupils are too small. When this happens, the device will notify you and suggest you adjust the room lighting. |
10. The results screen will appear at the end of the successful screening process. | Passing results will indicate screening complete. Screening results that are not passing are indicated with red highlights and "Complete eye exam recommended" will appear on the screen. |
11. Record the student's results. | |
12. Notify parents of non-passing results. |
