Investigation of Wearing Compliance of Spectacles for Myopia Control

November 13, 2025 updated by: CooperVision, Inc.

A Multisite Investigation of the Wearing Compliance of Spectacles for Myopia Control

The goal of this observational study was to compare the wearing patterns of spectacles prescribed for myopia control in juvenile wearers.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This unmasked, multi-center, observational study evaluated the wearing patterns of established (use of ≥3 months) juvenile spectacles wearers. It aimed to compare the wearing patterns of spectacles for myopia control between males and females. Wearing pattern were measured via the use of temperature sensors fitted to the sides of the participant's spectacles. Data from the final week of the 1-month study was used for analysis to minimize 'unusual' wear patterns which may have occurred early in the study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Juvenile participants recruited directly from the patient bases of several UK optometry practices who currently wear spectacles prescribed for myopia

Description

Inclusion Criteria:

  1. They are aged between six and 15 years old.
  2. Their parent or guardian understands the rights of the subject and are willing to sign a statement of informed consent.
  3. They understand the study at a level appropriate for their age and are willing to sign a statement of assent.
  4. They and their parents or guardians are willing and able to follow the protocol.
  5. They currently use spectacle lenses for myopia control and have done so for at least three months.
  6. They agree not to participate in other clinical research for the duration of this study.

Exclusion Criteria:

  1. They have an unusual ophthalmic history, which in the opinion of the site investigator or Principal Investigator might impact on the successful conduct of the study.
  2. They are amblyopic.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Overall Wearing Pattern of Myopia Control Spectacles
Time Frame: Measured continuously over 1 week of wear
Overall wearing patterns were evaluated via the use of temperature sensors fitted to the frame of the spectacles. The temperature readings from the final week of the one month study were used to determine when spectacles were worn or removed. Scores were calculated as the average times over a 24 hour period (W24) where a higher score indicated that the spectacles were worn for a longer period of time per day.
Measured continuously over 1 week of wear
Effect of Sex on Overall Wearing Pattern
Time Frame: Measured continuously over 1 week of wear
The effect of sex on the overall wearing pattern was evaluated via the use of temperature sensors fitted to the frame of the spectacles. The temperature readings from the final week of the one month study were used to determine when spectacles were worn or removed. Scores were calculated as the average times over a 24 hour period (W24) and a 'waking day' period of 07:00 to 21:00 (W14), where a higher score indicated that the spectacles were worn for a longer period of time per day.
Measured continuously over 1 week of wear

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 30, 2024

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
