Study Summary

This trial aims to determine how soft multifocal contact lenses affect presbyopic vision and accommodative & binocular vision disorders. They are designed to provide a range of clear vision at both distance and near by introducing a power gradient over the eye. Results will help us understand if center near designs provide a greater therapeutic effect for these disorders.

Who is the study for?

This trial is for individuals aged 18 to 30 with good vision (20/25 or better) in both eyes using their current contact lenses. They should have no eye diseases, surgeries, rigid lens wear, significant astigmatism (>1.00 D), or binocular vision disorders. Participants must not be on treatments affecting myopia control or accommodation.Check my eligibility

What is being tested?

The study tests how center near and center distance multifocal contact lenses affect accommodative function in young adults. It aims to determine if these lenses can help manage issues like difficulty focusing on close objects by comparing the effectiveness of different lens designs.See study design

What are the potential side effects?

While the trial doesn't explicitly mention side effects, typical ones from wearing contact lenses may include eye discomfort, dryness, redness, blurred vision, and a feeling of something in the eye.
