Love them!  I needed a replacement clear shades to protect my eyes from the wind and dust, and the sun while cycling; and these did the job.  I replaced my old one i bought else where, and it was making me see things further than they appear to be. This makes me see depth and distance as is and the lens are clear and not as concaved.
Its at a budgeted low price so i dont
worry about dropping and breaking it or losing it; definitely a must buy for sports enthusiast.
