BICON BIAS-F - Multifocal lens
The BICON BIAS-F is a bifocal contact lens for the correction of presbyopia.
presbyopia (presbyopia).
The front surface is divided into two clearly demarcated 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 produced at any required height.
The BICON is stabilized by a prism ballast. The support edge rests on the lower eyelid and thus contributes to the relative displacement when looking up close.
In addition to the standard back surface offered here, there are a number of special shapes that we do not offer online due to their complexity, but can be ordered after consultation by telephone (prices on request)
BICON BIAS-F VPT (front surface toric with stabilization prism)
BICON BIAS-F RT (rear surface toric)
BICON BIAS-F BT (Bitoric)
BICON BIAS-F BTC (Bitoric Compensated)
BICON BIAS-F BTX (Bitoric crossed axes)
Please only order this lens type if you are already wearing it successfully.
It will be made individually for you. Exchanges, cancelations or returns are excluded, even if the contact lens is in perfect condition.
Not sure if these are your hard lenses ???
