I just got a pair of photochromatics from zenni. i have also had transitions (on essilor lenses) from my optician - several times (as far back as a i can remember)
negligible differences between the transitions and the photochromatics - other than weight (the transitions were a higher index though so this is not a fair comparison) there is a slight possibility that the 1.57 zenni photochromatic may be a bit thicker than regular 1.57 lens they use ( i posted a thread about this a couple days ago but have had no responses to my query) my power is moderately bad though so all this thickness stuff will not apply to you unless you are like me: around a -4.25 or so the one thing of note here though: i have had a pair of transitions that i regularly used for going on 5 years, and the neutral shade (i.e. the base shade outside of light) has barely changed. I don't know how zenni lenses will be different - with time they may get discolored (i have heard that some photochromatic lenses do this) again - I just don't know if zenni lenses do this - they may not. I have not noticed ANY difference in the speed to change. have not noticed ANY difference in how dark they get versus transitions (seem comparable, zenni possibly lighter?) NO photochromatic lense works in a car due to the UV blocking of the windshield (i guess if you're in a convertible or sunroof open there is exception), and i agree with previous poster that they won't cut down on glare at all simply b/c they are not polarized - although the zenni anti-glare coating is better than i expected. on the whole I am VERY happy with the photochromatic effect on my zenni lenses compared to my transitions. and the price is VERY good. -- Check us out at the oft-updated http://glassyeyes.blogspot.com!
