I am a force personnel. I have been wearing a golden framed rayban sunglasses from that time. when I joined in force.my job is very rough and tuf. the glasses is fine n give a chill an coll look in summer and winter design is also good and stylish. but I think according to the price of the eye wear its frame should be dust proof and sweat and rust proof because I wear it at very roughly at dust places and in summer because of sweat and dust the glossy layer of the frame become rough soon.so the frame need to change earlier . I thing the frame should be dust and rust proof
