Summary

This study looked at how different types of multifocal contact lenses change the way young adults focus their eyes. Twenty people aged 18 to 30 with no other eye problems took part. Researchers measured eye focusing and teaming while participants wore two kinds of lenses. The goal was to see if these lenses work the same way as bifocal glasses for treating focusing issues.
