Patients who wear contact lenses face some new challenges as their near vision begins to weaken sometime in their mid forties. Previously, options for these patients included using reading glasses over their contact lenses, or correcting one eye for near (monovision). Both of these techniques involve some obvious compromises.
Bifocal contact lenses give patients the opportunity to use both eyes simultaneously for both distance and near. This provides a more natural vision for the patient who needs reading correction. There have been significant advances in the field of bifocal contacts in the last few years and now many patients achieve comfortable vision both at distance and at near with acceptable clarity using a convenient disposable product.
Recently, this technology has become available in a toric design for astigmatism.
