Bifocal glasses lenses explained

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
