In this video I explain the different types of bi focal lenses. There are different shapes and sizes of bifocal lenses and it's good to familiarize yourself with the options available. • The bifocal lenses shown here are: • D28 • D35 • R24 • R38 • C28 • The letter represents the shape of the seg (segment = the small section where the resting area is) • I.e D seg is D shaped • The number represents the width/size of the segment. • Feel free to ask any questions in the comments, theres lots more information about bi focals, this is just an overview. • Thank you for taking the time to watch and read my content. • Many thanks • Colin • #bifocals #bifocallenses #bifocalglasses
