ASCON
Hard gas permeable custom contact lens with UV filter.
ASCON® is the first contact lens with a progressive aspheric back surface design.
The back surface is spherical from the center up to an angle of 14°. After that, progressive flattening begins. The degree of eccentricity is indicated by the AS value in 30°.
In addition to the standard back surface offered here, the ASCON is also available in several special forms with toric back surfaces:
These lens types can be found in the section "Hard contact lenses (toric)"
Please order this lens type only if you already wear it successfully.
It will be made individually for you. Exchange, cancellation or return, even if the contact lens is in perfect condition, are excluded.
