Protocol - Use of Glasses and/or Contact Lenses as a Child

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*.

*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.

Requirements

Requirement Category	Required
Major equipment	No
Specialized training	No
Specialized requirements for biospecimen collection	No
Average time of greater than 15 minutes in an unaffected individual	No

Mode of Administration

Self-administered questionnaire

Lifestage

Toddler, Child, Adolescent

Participants

Children aged 12 years via parental proxy*

* While this protocol was used in a study of children aged 12 years, the Ocular Working Group suggests the same methodology can be used with children aged 18 years and under.

Selection Rationale

This assessment will provide information on rates and types of refractive correction used in childhood. Refractive errors, especially significant levels in childhood can be genetically influenced. The protocol selected is a standard, well-characterized instrument especially designed for assessment in the pediatric population.

Measure Name

Corrective Lens Use

Release Date

February 26, 2010

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.
