The Dallas Polarized Night Driver has a modified aviator frame that comes in pewter or gold. The frame has a spring hinge for a comfortable fit. This style does not have any magnification in the lenses. It works well for those people wearing contacts or for people not needing corrective lenses. The yellow lenses are so useful against nighttime driving glare. The lenses are also polarized which makes night images for distinct. Frame Measurements: 5 5/8" x 2" (temple to temple x height of lens)
