photo gray lenses
I recently got a new pair of glasses and like I have for the last 40 yrs, I paid extra for the photo gray. Used to be the photo gray was instant dark when you stepped outside and instant clear when you went inside. Both the new pair and the one it replaced [from 2 different stores] are instant dark but when you come inside it takes in the neighborhood of a half hour for them to go back to clear. I'd be interested in hearing from any members that wear the photo gray glasses and how theirs works. Today's glass lenses are a lot lighter than yesterdays but the photo grey option seems to have paid the price My daughter fits me with all the bells and whistles since I work in construction....Crizal scratch coating, polycarbonate shatter proof lenses, Titanium frames, and like you, Transitions. Mine take about 3 minutes or so to go back clear. You are right, lenses don't weigh anything nowadays. I'll ask her if there has been a change in the way they lighten/darken over the years. Interesting. I've ordered photogray/Transitions lenses for years, on both glass and polycarbonate lenses, and they've always taken a few minutes to darken or lighten up. My current Transitions lens are probably one year old, so I don't know if they've made any changes very recently. Used to be my photo gray lenses would take 1-3 minutes to go from light to dark or dark to light. Some pairs seemed to be better than others but nothing like my last 2 pair of glasses. It wouldn't be so bad but on a bright sunny day when you go in and out of the shop/barn and they don't lighten up for a long time - it's hard to see unless you have all the lights on I have two pairs of Transitions that I bought as part of a special and like you marksr it seems like they do take a while to clear up. Not maybe a half hour maybe around five minutes or so. One place I went to they had asked me had I been in the sun recently and I said no and asked why and the clerk said I am just asking because your glasses are still dark. Since I was in the place where I was going to buy my new pair of glasses I asked why and the clerk explained to me that over time the coating will stay dark all of the time. Actually I never noticed that much because the change was gradual over time. Still it is a shame for the price you pay to know the coating will do that. I first started wearing photo gray lenses in the early 70's and was immediately impressed! I don't know how many pairs of glasses I've bought in the last 40 yrs but I was always satisfied with the way the photo gray worked ..... until these last 2 pair. That is one reason I didn't go back to the shop that made my last pair. Over the yrs I've noticed minor differences in the different pair of glasses. Some just seemed to be better than others but they were all basically the same. I don't understand the big change in how the last 2 pair respond to light. The glass lenses in the last 2 pair weigh significantly less than any of my previous glasses, not sure how the reduced weight would cause the photo gray to be less effective...... if that's even related. Chinese counterfeits? . Ray - It is possible, but not probable. China is in a far different time zone and the glasses may not have had time to acclimate after the long flight due to the time difference (LOL). Dick Marksr, I think my first pair back in the late 70's were called Rinauld Reactomatics. Man, that's been a long time Before they had plastic lens, my photo grays with the glass lens would get really dark and take a good 10 minutes to lighten. My plastic lens photo grays hardly darken at all. Don't think I will pay for that option any more. You want them to darken fast??? Do like I did once and forget to remove them under a welding helmet Black is dark right??? I have since bought diopters for the helmet. I have used them for years. Started driving school bus and found that when you are bhind a windshield they do not work. Anyone else found that to be true. I still use glass lenses so I know it's not a problem with plastic. I've always been satisfied with how the photo gray option works except for the last 2 pair. I've never noticed any issue with them not darkening enough while driving..... but I've worn glasses since 3rd grade and have never had a pair of store bought sunglasses to compare them too. My wife thinks my glasses get too dark when I'm outside but it works for me. I just have issues with them staying too dark, too long, after I come inside Photochromatic lenses won't darken appreciably while you are driving. Sunlight is refracted through your windshield and does not react with the properties of the lenses. She also gets me sunglasses to wear while driving with the same prescription. I do have to remove my glasses for a minute or two if I enter a really dark building from outside, at least until they equalize. But that's better than having to keep up with clip on sunglasses You want them to darken fast??? Do like I did once and forget to remove them under a welding helmet Black is dark right??? I have since bought diopters for the helmet. Got a chuckle out of this post as it reminded me of my dad back when we use to service tanning beds (my parents owned a few stores and wholesaled beds and equipment). Everytime I'd fire up a bed to test, my dad's glasses would go instant dark. Would take his glasses a couple minutes to tame down. I tried them once about 10 years ago and haven't done it again. I had the problem Michael mentioned when driving (which I do a lot of ). Last few years have been using glasses with the magnetic clip-on's which I absolutely love.
