We don't supply bifocal lenses at IOLLA at the moment.
However, we do supply varifocal lenses which are available to purchase from our showrooms, and these gradually change from the distance prescription at the top of the lens down to reading at the bottom. These lenses are are more versatile and there is no visible line on the lens. We selected these over bifocals when we created our streamlined product collection which allows us to deliver such a great price to our customers!
