Up close, I could see perfectly without lenses. If that's the way you use them for diving and just need a slight fix, you might want to change your mind. How did I attach them? Based on other reviews, I decided to try two methods. On one side, I attached the lens to the inside of the mask, following the manufacturer's instructions (use water film and let dry as recommended). On the other hand, I glued the lens to the inside of the mask with RTV clear silicone and let it cure for a few days. In both cases I cleaned the mask with vinegar and then Zeiss lens cleaner. before application. how did it work The lens attached to the RTV was a bit blurry. I tried to make the glue layer as thin and even as possible, but there were some discrepancies. The lens adhered to the aqueous film was acceptably clear. The lens attached to the RTV broke off after 3 dives. The lens attached to the water film remained attached throughout the trip (about 20 dives). Energy) to try to reattach the RTV lens to the outside of the mask using the water film method.
