Multifocal contact lenses work by incorporating different lens powers into one lens, allowing for clear vision at multiple distances. These lenses have different zones that correct near, intermediate, and distance vision, similar to progressive eyeglasses. By providing multiple focal points, multifocal contact lenses help individuals with presbyopia see clearly at all distances without the need for reading glasses. **

In multifocal lenses, addition refers to the additional power that is added to the main prescription to allow for clear vision at different distances. This additional power is usually found in the lower portion of the lens and is used for close-up tasks such as reading or using a computer.

Bifocals have two distinct areas for near and distance vision, while trifocals have three areas for near, intermediate, and distance vision.

Each type of multifocal glasses has its own advantages and disadvantages, so it's important to consider your specific vision needs and lifestyle when choosing the right option for you. **
