Do I need bifocals?

I went to my optometric lastweek and my prescription says add +2.50, I forgot to ask what is that all about, but my sister told me I need bifocal lens, do you think my sister is right? or should I visit my optometrist office and confirmed what she wrote?

if you have ADD meaning you have reading power, or if you want to order read-only glasse or MULTIFOCAL LENS (bifocal or progressive), bifocal has a line in the center and progressive is called no line bifocal,
