text: This review is for the transition/photochromic lenses<br /><br />The lenses just very barely change shade. It's only noticeable if you cover part of the lense, let them sit in the sun and then you can see a fine line between the &#34;light&#34; and &#34;dark&#34;.<br /><br />The lenses are slightly thinner than true Oakleys but fit just fine in the frames. However, I got a little bit of a headache wearing them. I didn't visually notice any distortion, but they must be off just a little bit because after 10 minutes I had to take them off.<br /><br />The normal non-transition Walleva lenses are probably worth a shot for $10, but don't bother with these specifically.
