Add to My Toolkit
Description:

The respondent is asked a series of 5 questions to assess their child's current and past use of glasses and contact lenses, duration of use, and reason for use.

Protocol:

[ ] No (go to Q4)

[ ] Glasses

[ ] Contact lenses

2. How often are the glasses or contact lenses worn?

[ ] All the time

[ ] Most of the time

[ ] Sometimes

[ ] Hardly ever

[ ] Only when eyes feel tired

3. Why were the glasses/contact lenses prescribed? (you may tick more than one box)

[ ] Astigmatism

[ ] Short-sightedness/myopia

[ ] Long-sightedness/hyperopia

[ ] DK

[ ] Other (specify)______________

4. Has your child worn glasses or contact lenses in the past, but no longer needs to wear them?

[ ] no (go to end)

[ ] yes

[ ] Unsure (go to end)

If yes, please state the dated and age when first prescribed:______

Date stopped: (MMDDYYY)___________

Reason stopped:________

5. How often did you child wear their glasses/contact lenses?

[ ] All the time

[ ] Most of the time

Availability:

Publicly available

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 CategoryRequired
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

Life Stage:

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.

Specific Instructions:

None

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.

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.
