Why are glasses lenses so expensive?

Standard multifocal lenses – $150

These lenses provide clear vision at distance, intermediate and close-up, but there can be some noticeable areas of soft focus at the edges of your vision.

More expensive than single-vision lenses and bifocal lenses. Progressive lenses are more expensive because you’re basically getting three eyeglasses in one. In addition, you’re paying for the convenience and extra time that goes into creating a multifocal eyeglass with no lines.

Are multifocal lenses worth it?

Multifocal IOLs improve near, intermediate, and far-distance vision, varying with the lens model chosen. In many cases, after having the lenses implanted, people no longer need to wear corrective lenses to see clearly. No upkeep or routine replacement necessary. The results of multifocal IOLs are long-lasting.
