Standard V is optimally designed to balance the need of the wearer for visual acuity without sacrificing the comfort in wearing.

Standard V is designed very much with the wearer's comfort in mind. Experience no discomfort or headaches that are common to bifocal wearers moving to progressive lenses. Standard V is so easy to adapt to because the computer simulation technology allows different powers to blend smoothly into each other. A no frills Progressive lens that allow wearers to migrate from bifocals/trifocal lenses naturally and comfortably.
