Which blending level is the default if not specified in GP lens blending options?

Explanation:
In GP lens blending, the level determines how smoothly the edge transitions from the optic zone to the peripheral area. When no blending level is specified, the system uses a medium blending level as the default. This middle setting provides a balanced compromise: it’s gentle enough to be comfortable and preserve tear film, yet strong enough to avoid a noticeable hard edge or instability at the lens edge. A light blend can lead to a less defined edge and potential comfort or fit issues, while a heavy blend can thicken the edge and affect both comfort and optics. The option of not specifying a value isn’t itself a usable setting; the default fallback is the medium level.
