ClinConnect Summary

This clinical trial is studying a special type of glasses called Diffusion Optics Technology (DOT) spectacles to see if they can help slow down the worsening of myopia, commonly known as nearsightedness, in Chinese children. The trial will last for 12 months and is currently looking for participants. Children between the ages of 8 and 14 who have previously taken part in a related study may be eligible to join. To participate, they will need to wear the DOT spectacles for at least 10 hours each day and agree not to use contact lenses or other treatments for myopia during the trial.

Parents or guardians of potential participants will need to read and sign a consent form indicating they understand the study. It’s important to note that children with certain allergies to specific eye drops cannot take part in this trial. Overall, participants can expect regular check-ups to monitor their vision and how well the glasses are working throughout the year. This study aims to gather more information about the safety and effectiveness of these glasses in helping children with myopia.
