ClinConnect Summary

This clinical trial is studying a new way to help people with presbyopia, which is a common condition that makes it hard to see things up close as we age. The researchers want to see if training using special 3D visuals—without the need for glasses—can improve how well individuals see and process visual information. They will use advanced techniques to look at how the brain reacts to this training and determine if it helps improve visual comfort and skills.

To participate in this study, you need to be between 40 and 60 years old and have specific vision requirements, such as a certain level of eyesight correction. If you’re interested, you’ll be asked to understand the study's purpose and sign a consent form. Participants can expect to undergo training sessions and have their brain activity monitored before and after the training. This study aims to offer a promising, non-invasive way to enhance presbyopia treatment and could lead to new insights in eye care and brain health.
