Question about Apple Clear Case with MagSafe

Yes, the magnifying glass is visible, but other suppliers also have a version with the magnifying glass in anthracite and this is less noticeable depending on the colour of the smartphone. The anthracite version would, for example, be less or not at all noticeable on smartphones that have a darker colour scheme.

This "magnifying glass" is needed for charging with MagSafe, so yes.
