These striking black and white glasses by Zenni were ordered in the long distance prescription of my partner Nel who subsequently chose them for use in everyday life. Zenni has an upper limit of -10.00 for progressive lenses so I ordered an empty frame and then had it fitted with progressive lenses by ciliaryblue in England. Note the myodisc effect at the edge of the left lens. Zenni did this extra work without any charge so that the glasses could make their journey, neatly and safely folded in their case. Up Zenni!
