CUSTOM FLEX 38 STANDARD
Concentric bifocals with distance or near centres (See fitting guides for assistance with choice)
These are designed to optimise handling and durability. centration is extremely important and larger diameters work better. The choice of segment depends on the size of the entrance pupil (combination of AC and pupil size)
This unique design available in soft or RGP is centre distance with a variable distance seg.
It overcomes the problem of small pupils and shallow AC's. We can vary the eccentricity as well as the seg size to make a lens that will fit most eyes. (see our fitting guide.)
Centration is essential and you can choose a base curve and diameter to optimise the fit.
We prefer to use our custom flex 60 material for the soft design.
