Designed to answer the needs of the growing presbyopic population worldwide. The
Boston MultiVision gas permeaable (gp) contact lenses are made from
the
Boston ES (enflufocon A) fluoro silicon acrylate material with a water
content of <1% by weight. The lenses consists of a back surface aspheric design
intended to provide distance and intermediate correction with a reading addition
of +1.50D. The base curves range from 7.3 mm to 8.3 mm, in 0.1 mm steps, with an
overall lens diameter of 9.6 mm. The lens parameters and lens design were chosen
to maximize the ease of fit.
