BRIDGE AND LENS STAY
The lens is screwed at one point on the bridge at the lens stay. The saddle bridge style presents gentleness. Daily stress on glasses are effectively eliminated by positioning the contact path of the guide rim and gyaku-R hinge far apart as possible.
Ideal front stability and comfort is illustrated from gyaku-R temple that constructs gyaku-R and the temple together. Moreover, its curving structure makes sure to wrap its temple around the head comfortably.
To raise correspondence to stress, different range of thickness are given to the guide rim. They are designed thicker around the bridge and thinner closer to the front end piece when observed from the top. The saddle bridge like style performs a classic style. The style changes from angles observed.
O-16T has Type A and B in different eye depth of square lenses.
