Tell me how is the bifocal mode is created in this ? In normal glasses which we wear, we have those called bifocal lenses( short & long sight)..which obviously require diffrent focal length glasses ..integrated .Now how is this achieved in the contact lens ? Considering the fact that the contact lens has to to match with the curvature of the eye pupil ?

This was recently explained to me by the optometrist. She said that if I choose to have contact lenses, then they would make one lens which is for the distance and the other for things that are near. Apparently the eyes work together so having them like this doesn't do any harm, as the lens would be made for the weaker eye seeing in the distance and the other lens would be for the eye that is weaker seeing things close up.
At least that is my understanding of what she said. LOL

Hello..this sounds some what better..fine..that takes care of individual eyes..different lenses..fantastic..still the question remains how distant & short vision are adjusted in the same lens ?
