There are over 35 different progressive
invisible bifocal designs. Some manufacturers even offer more that one
design. An older design along with a newer updated one, or two
different designs are offered to satisfy different applications or
different retail price points. We have found the Varilux Comfort and
Sola Percepta to be very nice lenses with a high degree of user
adaptability.
Progressive invisible bifocals are not for
everyone. It is the job of the optician to help you decide which lens,
visible or invisible, would be best for your application. It's the job
of the optician to make sure the lenses will work in the selected
frame and are measured properly for you. Opticians are like everyone
else, not all are the same.

No unsightly line
*
Gradual change in power from top to bottom
results in no image jump as is found in line style
bifocals.
*
As your needs for close up power increases, these
lenses will give vision at all
distances.
