BICON ASCON - Multifocal lens
BICON ASCON is a bifocal contact lens for the correction of presbyopia.
presbyopia (presbyopia).
The front surface is divided into two clearly defined zones for distance and near.
The optical centers of the distance and near parts lie on the dividing line.
This monocentric design achieves image jump-free vision.
The addition can be made at any required height.
The BICON stabilizes by means of a prism ballast. The supporting edge causes the lens to rest on the lower eyelid and thus contributes to the relative shift when looking close up.
In addition to the standard back surface offered here, there are also several special shapes, which we do not offer online due to their complexity, but can be ordered by telephone (prices on request).
BICON ASCON VPT
(front surface toric with stabilization prism)
BICON ASCON RT
(back surface toric)
BICON ASCON BT
(bitoric)
BICON ASCON BTC
(bitoric compensated)
BICON ASCON BTX
(bitoric crossed axes)
Please note that individually manufactured hard lenses can only be returned in case of an obvious quality defect.
So only order if you already wear exactly this type of lens with success.
