Protocol - Contact Lens Use- Adult
These self-administered questions are used to assess an individuals current and past contact lens use. The respondent answers an initial question regarding current contact lens use. The respondent then proceeds to a set of two follow-up questions based upon the response to the initial question.
If the respondent answers "no" to the first question, then the respondent should proceed to the first two follow-up questions. If the respondent answers "yes" to the first question, then the respondent should proceed to the second two follow-up questions.
1. Do you currently wear contact lenses?
If no to #1:
a. Have you ever worn contact lenses?
b. Are you considering wearing contact lenses in the next year?
If yes to #1:

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)
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.

Corrective Lens Use
February 26, 2010
Questions to assess current and past use of eyeglasses and/or contact lenses.
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.
