What is the purpose of this trial?

This trial tests special glasses designed to slow the progression of nearsightedness in children. It compares two types of glasses: one featuring the new SightGlass Vision Diffusion Optics Technology (DOT) Spectacles and a standard type. The goal is to determine if these new glasses can safely and effectively aid children with nearsightedness over three years. Children who completed a previous study with these glasses and can wear them daily for up to 10 hours may be suitable candidates. As an unphased trial, this study provides a unique opportunity for participants to contribute to innovative research that could benefit children with nearsightedness.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that SightGlass Vision Diffusion Optics Technology (DOT) Spectacles are safe for reducing juvenile myopia?

Research has shown that SightGlass Vision Diffusion Optics Technology (DOT) Spectacles are generally safe for children. In an 18-month study, more than half of the children wearing these glasses did not experience significant worsening of their nearsightedness, suggesting the glasses are effective without causing harm.

Additionally, data from a 12-month study confirmed that these glasses are safe and help slow the progression of nearsightedness. They also offer a visual experience similar to regular glasses, allowing children to wear them comfortably without major issues. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike the standard glasses for nearsightedness, which typically just correct vision, SightGlass Vision Diffusion Optics Technology (DOT) Spectacles are unique because they use a special lens technology that aims to slow the progression of nearsightedness. Most treatments focus on helping people see clearly in the present, but these spectacles utilize a diffusion optics method that changes how light is focused on the retina, potentially limiting the worsening of vision over time. Researchers are excited about this innovation because it not only helps with current vision needs but also addresses the underlying progression of nearsightedness, offering a proactive approach to managing this common eye condition.

What evidence suggests that SightGlass Vision DOT Spectacles are effective for reducing juvenile myopia?

Research has shown that SightGlass Vision Diffusion Optics Technology (DOT) Glasses can slow the progression of nearsightedness in children. One study found that kids wearing DOT lenses experienced significantly less worsening of their nearsightedness compared to those with regular glasses. Over half of the children using DOT lenses showed no significant decline in their vision. Another study discovered that these glasses also slowed eye growth, which is crucial for controlling nearsightedness. In the CYPRESS Extension Test Arm, participants will receive DOT Glasses, while those in the CYPRESS Extension Control Arm will wear regular spectacle lenses. These findings suggest that DOT Glasses could be an effective option for managing nearsightedness in children. ^{2 3 5 6 7}

Are You a Good Fit for This Trial?

This trial is for kids who were in the CYPRESS study and can commit to wearing special glasses for up to 3 years, at least 10 hours a day. They shouldn't have been out of the previous study for over 30 days and must not wear contact lenses during this time. Parents or guardians need to consent.

Inclusion Criteria

Agree to wear the assigned spectacles constantly except for sleeping, swimming, or other activities in which spectacle wear would be dangerous or otherwise not possible (minimum of 10 hours per day)

Willingness to participate in the trial for up to 3 years without contact lens wear

Previously a successfully completed participant in the CYPRESS study (NCT03623074) and having not exited this study for more than 30 days

Exclusion Criteria

Known allergy to proparacaine, tetracaine, or tropicamide.

What Are the Treatments Tested in This Trial?

Interventions

• SightGlass Vision Diffusion Optics Technology (DOT) Spectacles
• Spectacle lenses

Trial Overview

The trial tests SightGlass Vision Diffusion Optics Technology (DOT) Spectacles' long-term ability to slow down worsening near-sightedness in children compared with regular glasses, monitored over a period of three years.

How Is the Trial Designed?

Group I: CYPRESS Extension Test Arm Experimental Treatment 1 Intervention

Single vision, impact resistant spectacle lenses; CYPRESS Test Arm 1 and CYPRESS Test Arm 2 will move into CYPRESS Extension Test Arm

Group II: CYPRESS Extension Control Arm Placebo Group 1 Intervention

Single vision, impact resistant spectacle lenses; CYPRESS Control Arm remains in control lenses as the CYPRESS Extension Control Arm

Published Research Related to This Trial

In a study of 11-year-old children with myopia, using monovision spectacles resulted in significantly slower myopia progression in the near corrected eye compared to the distance corrected eye, with a difference of 0.36 D/year.

While monovision did not effectively reduce accommodation, it suggests that maintaining myopic defocus can help slow down the axial elongation of the eye, which is a key factor in myopia progression.
