A Digital lens features what options for the add power boost?

• A. +0.25
• B. +1.00
• C. +0.50 or +0.75
• D. None of the above

Answer: (C)

Digital lens technology lets you customize near addition with a small boost to the reading power. The add-power boost is a precise, limited increase that improves close work without upsetting distance or intermediate vision across the lens. In practice, the boost options are typically +0.50 diopters or +0.75 diopters, because these provide a noticeable near enhancement while preserving overall optical balance. A boost of +0.25 is usually too subtle to make a meaningful difference, and +1.00 would raise near vision too much, potentially causing distortion or imbalance between vision zones. So the standard digital lens boost options are +0.50 or +0.75 diopters.
