i already bought close to 5 pairs of frame with lenses online and 1 more on the way... no problem with fitting....

.. first of all they will state all the length of all the parts of the frame.. 2nd u can upload yr face pics and roughly see the frame suit yr face or not... 3rd... u can actually adjust the frame yrself when it reach u to contour yr head... After learning few tricks i no more visiting local optical shops... local shop optician most dun know how to adjust the frame to make it comfortable... i can myself do it much better... I also done for my loves one... they no more specs sliding down issue. no more pain here or there behind ear
