FT-28/35 is an example of which type of lens option?

• A. UV protection lens
• B. Glass sole
• C. Aspheric option
• D. Multifocal option

Answer: (D)

FT-28/35 represents a multifocal lens option because it denotes a design that delivers more than one focal power, letting a wearer see clearly at both distance and near without switching glasses. This kind of option is chosen for presbyopia or tasks that require multiple viewing distances, such as reading and looking at objects at arm’s length. The other choices describe properties or features that don’t inherently create multiple focal powers: UV protection is about blocking ultraviolet light, aspheric refers to the lens surface shape that can improve optics but isn’t itself a multifocal design, and “glass sole” isn’t a standard lens option. So FT-28/35 aligns with a multifocal configuration.
