GAS PERMEABLE CONTACT LENSES
Menifocal Z technology has developed its
optical partition that is designed for center portion for distance and
periphery portion for near. This unique concentric design takes advantage of
obtaining both clear and natural vision. When we look straight to focus
distance image, Menifocal Z can match its center optical zone for distance with
the pupil. Similarly, when looking downward to focus near images, Menifocal Z
can match its peripheral optical zone for near with the pupil.
Menifocal Z sets the distance optical zone
on center so that it can give same distance visual acuity and same lens
thickness as typical oxygen permeable contact lens. There is little difference
between Menifocal Z and typical RGP lenses in fitting. Menifocal Z can ensure
its maximum bifocal performance without losing the original advantage of oxygen
permeable contact lenses.
Menifocal Z has unique advanced optical
zones that slightly change the partitioned ratio among distance optical zone,
near optical zone and transition zone according to parameters of additional
power, which results in giving good vision to every age of wearers who are
trouble with presbyopia.
