I sold my Index on eBay and somehow during shipment black bits of old foam or something fell out and were visible in the screen so I had to give him a refund. I took the lenses out from the front. I heated them up carefully with a heat gun and used a suction puller and a steel spudger but I slipped and scratched one lens They came out (just one side) seperated. I cleaned all the gunk out and reassembled it. Two years ago - still using it every day. the scratch which is quite clearly visible is not really visible close up strangely enough so it doesnt interrupt my gaming. Now that I have removed a lens I am comfortable that I could easily remove an Index lens. (ratcat17@hotmail.com)
