- Bifocal Lenses Presbyobia is a focusing condition where by one cannot
focus to read comfortably. In these cases bifocal lenses are a great
option to keeping two sets of different spectacles. This type of
lens has a distinct line that is visible between the part of the lens used
for distance and reading.
- Progressive Lenses (aka No-Line Bifocals) this is a step above the
traditional bifocal lenses, taking out the line in the middle of
the lens and making a more natural progression (correction) from distance
to near.
