One fail-safe method is to cover the lens.
Use a plain "Band-Aid" (no kidding), positioned so the soft fiber pad is over the lens. This reduces scratching.
On the extreme end of one half, fold a 1/2" section back on itself (sticky to sticky) which creates a "pull tab" so you can un-mask the lens when you want it. Secure the other end on the other side of the lens.
