Single Vision Lenses have one field of vision. You are either near-sighted or far-sighted.
Lined Bifocal
Lined Bifocal Lenses have two fields of vision, allowing you to see both near and far with one pair of glasses. They will have lines in the lens to distinguish between the two fields of vision.
Standard Progressive
Standard Progressive Lenses allow you to see clearly both near and far, and at distances between, with a seamless transition.
Custom Progressive
Custom Progressive Lenses help wearers see near and far without the lines bifocals are known for. These lenses are tailored to meet your eye’s needs and can generally fit into smaller frames than standard progressive lenses can.
