my sunglasses find at payless

Zebra Stripe SunglassesAren't these kinda neat-o? I bought a different style this weekend (black with subtle sparklies on the sides); but I also like these. My only reservation: can I trust the UV protection in a pair from Payless? They were only $9.99. Can you get reliable UV protection for $9.99? I hope the answer is yes, because I really like the style.[above image from Payless.com]
