      Recommended limits if fitting prescription lenses

      If your prescription is higher than the advised limits

      If your prescription is higher than the advised limits quoted above for this frame, it may be possible to fit your lenses into this frame if you use Ciliary Blue rather than a high street optician to fit them.

      This is because Ciliary Blue have specialist lens finishing equipment that is not available to most opticians. If you have a higher prescription than the limits advised above, we recommend that you call Ciliary Blue on 01455 293417 to check the feasibility before you order the frames from us.

            Fitting advice - please read before ordering!

            • Ziena glasses are not suited to people with a small head or slim forehead
            • If you have an Asian facial structure with a wider forehead, high cheekbones and shallow nose bridge, the Ziena SeaCrest is recommended
            • Be aware that when wearing Ziena glasses, your field of peripheral vision is slightly less wide. To accommodate this you need to turn your head a little further to check that all is clear when manoeuvring on a bike, for example.
