I think this is nasty spam.

My office manager saw Liquid Lense advertised and we had a patient ask about
it.  So we shelled out about $20 Canadian and bought some.  Tried it on some
heavily scratched donation lenses.  The  result:  imagine painting a lens
with clear nail polish --drips, brush marks etc made the lens useless-- took
out the scratches but added many distortions just like Victorian window
glass.

This is just advertising.

I had a patient who came in and showed me his glasses after using this
stuff.  It leave a terrible coating on the lenses that looks like an oil
slick-- chromatic fringes, etc.  He claimed it distorted his vision and
rendered his scratched lenses totally unusable.

Snake oil.
