The mask is ground perscription lenses. 5.5 in one and 6.5 in the other.You use the 5.5 - 6.5 power stick on lens?
They worked fine for 20 years. Then as I got older I needed bifocals on land to read. But still ok in water because nothing to read. Then as gages got more complex with smaller print I needed to do something.
The stick ons were for reading fine print on dive computer.
