Gets the job done.
I use the 2.5mm ones as they make my eyeglasses sit up higher and feels more comfortable. I have to change them out every 2-3 weeks, sometimes one... I just clean my lenses too often (2-3 times a day) and I tend to hit the nose pads which agitates the adhesive to the point where they no longer stick... When my skin gets oily, they do slip.<br /><br />Bottom line is they get the job done... I also noticed that the adhesive can be peeled right off the silicone, leaving bare silicone... Having thoughts of using a very very minuscule amount of permanent glue to keep them on, however afraid to get the glue on the lenses.<br /><br />Never had to trim the nose pads by the way. Direct fit on Prada eyeglasses. (Style: VPR-15Q).
