Push Lense Case
It is a product that can attach and detach lens without using hand by attaching hard lens case and an absorber. 
Designed as a case/holder, and even an applicator, the Push Lens Case allows you to store your lenses efficiently, without mixing up the left and the right. It also lets you apply your lenses without the aforementioned (albeit rare) woes.
It has the advantage that it can be used more cleanly than existing products because it can not be reached by hand. 
The case also adopts a clever truncated cylindrical design that prevents it from rolling off surfaces like tabletops.
