Take changing light conditions in stride with the Ryder Polarized Strider Photochromic Sunglasses. The rugged polycarbonate lenses automatically adjust based on the outside light to eliminate squinting from blinding brightness or dusky dimness. Polarizing technology doesn't create rifts but does make your colorful world zing with vibrancy. Between the wrap around style and lens technology, your eyes are safe from 100% of UV rays and blue light up to 400nm. Whether you're riding your bike or running at high noon, hydrophilic nose and temple pads prevent the Strider from slipping down your sweat covered face.
