Tifosi Optics Elder Photochromic Sunglasses

You can find years and years of innovative optics embedded in Tifosi's Elder Photochromic Sunglasses for all your fast paced adventures. Their Fototec photochromic lenses automatically darken or lighten in different brightnesses, and select lenses feature True Polarization for permanent glare elimination. You can also switch the lenses out for different tints. Tifosi made the lenses out of scratch resistant, shatterproof polycarbonate and treated them with a hydrophilic coating to repel raindrops and sweat. The lenses also feature ventilation slits for airflow, a Glare Guard to deflect reflection, and an optically decentered design to eliminate distortion. Grilamid TR90 makes the Elder's frame flexible, surprisingly strong, and comfortably lightweight. There are adjustable nose pads for a secure grip.
