Indoor Progressive Lens
(aka Near Variable Focus/ Computer/Occupational)

• Eliminates problems with progressive wearers needing to tilt head back to see things at arms length (ie Computer, Dishes, Auto Repair, Plumbing, etc.)
• These lenses provide near distortion-free mid-range variable vision when looking straight ahead and increase in power as wearers look down providing their reading prescription.
• Their simplified progressive design reduces distortion in the periphery.
• Little or no distance prescription so it is designed as a complement to a progressive rather than a replacement.

"Value" Progressive Lens

• Also called "no-line bifocal" or "no-line multi-focal" lens
• Contains all of wearers prescriptions from distance to reading (estimated 500+ points of focus vs 2 in bifocal and 3 in trifocal)
• Able to see clear and comfortable at any distance
• Available in "hard" (wide field of view for distance and near but very limited intermediate zone) or "soft" (smaller field of view on distance and near but wider intermediate zone and easier to traverse corridor) design

Multi-Design Progressive Lenses

• All the advantages of "value" design with increased field of view and easier adaptation
• Combination of "hard" and "soft" designed progressives to allow for wider distance and reading portion without loss of intermediate zone

Digital Progressive Lenses

• Digitally surfaced to decrease unwanted distortion up to 10x
• All the advantages of multi-design with increased field of view and easier adaptation
• Prescription modified to compensate for changes from the exam room to the real world

Freeform/Individual Progressive Lenses
