ASH: Myopia study for children & youth

In this study we are assessing how the eyes focus through a novel spectacle lens designed that slow down the progression of myopia (near-sightedness). We want to evaluate how eyes focus with these new lenses, and with two other lenses for comparison. Each pair of spectacles will be worn for approximately 20 minutes each, one after the other at a single study visit.

About the study

This study is completed in a single visit. If you/your child is found eligible to continue to the measurement session, you/they will be asked to wear each of the 3 pairs of spectacles for 15-20 minutes each, one after the other. Following 5 minutes adaptation to each pair, some focus measurements will be made.

•             Screening to determine eligibility                 0.50 hours

•             Study spectacle wear & measurements       1.25 hours

                         *Total time commitment –   1.75 hours

The study visit includes standard procedures that would often be encountered during a regular eye exam. No eye drops are used, the equipment does not touch the eyes or use bright lights.

What are the requirements?

To be eligible for this study, you must meet the following criteria:

•             Aged 6-18, inclusive

•             Currently either wear or require spectacle of low prescription (no more than -0.75 each eye) or are a current contact lens wearer (any nearsighted prescription)


In appreciation of the time involved, you/your child will receive $40 upon study completion. Parking passes will be provided as required.

How to participate

If you/your child are interested in participating, please email with the subject line “ASH.” You will be provided with all relevant study information prior to study enrollment, and you/your child are under no obligation to participate.

Safety during COVID-19  

We want to let you know that we have revised several of our protocols to keep participants and researchers safe during the pandemic, including enhanced cleaning and mandatory wearing of masks by everyone. Measures we have taken to reduce the risk of exposure to COVID-19 are explained in the “Information Letter: COVID-19 Risks for In-Person Research Study Visits” which we will ask you to sign in the event you participate.

Please note that you/your child will be within 2m (6 feet) of the researcher during some or most of the study visit time.  At all times, the furthest possible distance will be maintained.
