1.499/1.56 CR-39 progressive eyeglasses lens with HMC and EMI coating

In addition to cosmetic advantages, progressive multifocal lenses provide a more natural correction of presbyopia than bifocal or trifocal prescription eyeglasses.

Instead of having just two or three lens powers like bifocals or trifocals, progressive lenses are true "multifocal" lenses that provide a seamless progression of many lens powers for all viewing distances.

With progressive lenses, you can look up to see clearly across the room and in the distance. You also can look ahead to view your computer in the intermediate zone and drop your gaze downward to read and do fine work comfortably through the near zone of the lenses.

And it's easy to adapt to today's modern progressive lenses.
