Single Vision:
Single vision lenses provide
vision correction over the
entire lens. They correct a
single, particular vision.
Suitable for either distance,
computer or reading.
|
BiFocal:
Are corrective lenses with
two different optical powers.
The top part of the lens is for
viewing far-away objects and
the bottom part is for reading.
|
VariFocal:
Combine distance, reading + intermediate prescriptions. Varifocals gradually change from top to bottom.
They look just like single vision lenses.
They don’t have a
visible line
like bifocals.
