What is true about multifocal contact lenses?

Multifocal contact lenses are designed to address the vision needs of individuals who have presbyopia, a condition typically associated with aging where the eye's ability to focus on close objects diminishes. These lenses feature multiple prescription zones that allow the wearer to see clearly at various distances—near, intermediate, and far.

The unique design of multifocal lenses accommodates different viewing requirements without the need for switching glasses, providing a seamless visual experience in daily activities, whether the wearer is reading, using a computer, or driving. This versatility is what makes them crucial for people experiencing changes in their vision due to aging or other factors.

Other options focus on limitations: designing multifocal contact lenses solely for distance correction would not address the common needs of individuals with presbyopia. Similarly, stating they can only correct near vision does not accurately represent their multifocal capabilities. While some multifocal lenses may be designed for varying replacement schedules, such as monthly or daily disposables, it's not accurate to suggest that all multifocal lenses must be replaced monthly, as manufacturers may offer different replacement schedules based on the lens type.
