Bifocals/Progressives is a type of prescription that can be used to correct both near and farsight requirements. This means you can see your whole field of vision without switching between multiple pairs of glasses.
Bifocals (sometimes called “lined bifocals”) contain two prescriptions within the same lens and can correct both nearsight and farsight vision requirements. The top portion of the lens is used for distance, while the bottom portion of the lens is used for closer vision. The contrasting lense sare separated by a noticeable line.
Progressives glasses are multifocal lenses that contain at least three prescriptions. They have 3 main fields of vision, including near, intermediate, and distance. However, progressives do not have a visible line between prescriptions. This gives the wearer a seamless and uninterrupted transition when looking from up-close objects to far-away distance.
Firmoo provides bifocal lenses and progressive lenses. Start by selecting a frame with a height over 30mm to enable the function of bifocal or progressive lenses and then input your prescription as requested. Please note bifocal/progressive lenses are needed when there is ADD in your prescription.
