Personnel and Training Required
These questions may be self-administered (as in the source protocol) or administered by an interviewer with a pencil and paper or computer-assisted interview.
The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e. tested by an expert) at the completion of personal interviews.* The interviewer should be trained to prompt respondents further if a "dont know" response is provided.
*There are multiple modes to administer this question (i.e., pencil and paper and computer-assisted interviews)
Equipment Needs
Either a pencil and paper or computer-assisted instrument may be used. If a computer-assisted instrument is used, computer software may be necessary to develop the instrument. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire.

Definition
Questions to assess current and past use of eyeglasses and/or contact lenses.
Purpose
Determine the use and need for corrective lenses. Use of glasses or contact lenses, and their timing of use in a pediatric population provide insight regarding effects on visual function, influence refractive error development and progression, and task performance. It is important to determine the history of use of contact lenses because it has been shown to be associated with corneal conditions, such as infections and dry eye syndrome.
