Summary

This study looks at how people with presbyopia (age-related blurry near vision) feel about wearing multifocal contact lenses compared to regular contact lenses plus reading glasses. About 30 adults aged 40 and older will try both options and report which they prefer. The goal is to see if multifocal lenses offer a more convenient solution for seeing up close without needing separate glasses.
