I purchased two pairs of glasses, at different times, a pair of reading glasses and a pair of computer glasses.
Upon receipt of each pair, there was no adjustment required to the fit of the different frames and the quality of the two lenses were 'spot on' to the Optometrist's prescription. The fits were comfortable the the quality of my vision improved in each situation to the requirements prescribed.
Overall excellent value for my purchasing dollar and 100% satisfaction with my eyesight.
