If you wear thick specs like mine and want to stop marking your psvr lenses with your glasses then print 2, these are blu-tacked or double sided taped onto either side of the lens and stop specs from contacting the lens.
Also holds your specs up your nose.
I used designspark mechanical to create and model file is included if you need to modify it.
It does not affect visibility or come near the face, at least not mine, so it can be left fitted for users with no specs as well.
