Which progressive lens is not customized?

• A. Definity
• B. Physio 2.0
• C. Varilux
• D. Light H

Answer: (D)

The main idea here is how customization affects progressive lenses. Some progressives are tailored to the wearer’s individual measurements and frame geometry, using data like fitting height, pantoscopic tilt, wrap, and even pupil position to shape the lens for that person. This personalization helps ensure the zones for distance, intermediate, and near align with where the wearer actually looks, reducing eyestrain and improving peripheral vision.

Light H is a standard, non-customized progressive. It uses a fixed design that isn’t adjusted for an individual’s frame measurements or unique eye geometry. Because it isn’t personalized to the wearer, it won’t automatically align the zones with the wearer’s pupil centers or account for how their frame sits on their face, which can impact comfort and visual accuracy. The other lines are positioned as customizable or personalized options, so Light H stands out as not being customized.
