If the member wants to upgrade their lens material, what is required?

When a member desires to upgrade their lens material, the primary requirement is the payment of the price difference associated with the upgrade. This means that if the upgraded lens material has a higher cost than the standard lens, the member must cover that additional cost.

The rationale behind this is that different lens materials offer varying benefits, such as increased durability, weight reduction, improved optics, or other performance features, which can justify a higher price point. Therefore, it's standard practice within optical departments to require customers to pay the difference for enhanced products or services.

The other considerations, such as needing supervisor approval or waiting for a specified time, do not align with the typical policy for upgrades. Typically, upgrading lens materials is a straightforward transaction as long as the member is prepared to handle the associated costs.
