Game changer for the nose pieces that are a pain.
The nose pieces on my glasses routinely hurt my nose, and if I loosen them, then they slide down.  These immediately were soft upon my nose, and do not slide.  The ONLY downside is they seem to not have enough adhesive substance.  And, they want to come off.  CLEAN the nose pieces with alcohol first.  They do not come with instructions but pretty self explanatory.
