thickness is an important feature
After wearing my glasses with the anti-slip adhesive silicone pads placed as designed for 1 day, I had to alter pads, as they were too thick for me, causing a headache.  I removed the thick portion altogether and am now using the smaller portion of the pads.  They feel much better now.  Best not to wear them or leave them a steamy room, i.e., bathroom during a shower, as the pads may loose their grip.  So far the adhesive it working well.
