Well, l have to report that the JML magnifying glasses didn't work at all for me. Of course too early to be looking for eggs, so experimented with small the smallest objects l could find in the house. Initial results:
Wearing the magnifying glasses in addition to my own varifocals, inside the veil, only increased the 'swimming' effect.
Wearing them in addition to reading glasses did help a bit.
They did, however, work quite well by removing the veil and peering closely at the objects. Obviously removing the veil would not be the optimal plan.
The best result was, reading glaases, regular magnifying glass, and no veil.
I think l shall have to invest in a Sherriff clear view hood after all (as S entinel seem to only make the complete bee suits). I do like Cole Lynch's idea of a DIY veil, but don't think l'd have the courage to take scissors to an otherwise good bee jacket.
