There’s no other eyewear system like LEXA. The patented ellipsoidal shape follows and blends with the facial outline to provide optimum, full coverage. This nosepiece design is soft and pliable so wearers can shape it specifically for their noses. And, once it’s shaped, it stays that way. Temples adjust to four different lengths to correctly fit different faces. Wearers can adjust Lexa to three different lens angles for a customized fit.
