I was able to snap
I was able to snap the foam seal of the glasses and replace them easily. The lenses were a different issue. It is hard to remove the old scratched lenses and hard to snap the new ones into place. I followed the instructions on YouTube from several sources because no instructions on, how-to, were sent with the replacements! I wish they had sent instructions.
Once I got everything replaced and washed the glasses everything was perfect and I loved the product, the Wiley X Gravity glasses used for Motorcycling. I will keep replacing these items until the frame eventually gives out which should be years from now.
