I have multiple A Frame Replacement Lenses. I spend the majority of my winter skiing in Vermont which is notorious for flat light. I primarily use the H.I. Persimmon from November to February with the exception of blue bird days. This lens provides great contrast in flat light. I generally switch to the Fire Iridium or Black Iridium lens on blue bird days. These lenses filter out much more light and prevent you from feeling blinded by snow glare on sunny days.

Oakley provides plenty of other lens options worth checking out at http://oakley.com/pd/1650 The site is really good for determining what lens to pick based on the conditions you ski or ride in most. I'd also recommend following Oakley's instructions for swapping out lenses, as it can be more difficult then expected.

you can see everything, even in the darkest, gnarliest storms with the HI Yellow lens. I can't say enough good things about the contrast this lens provides

Easy lenses to replace. The color is good for bright light. Didn't get to use them much b/c I got them a few days b4 the season ended. Only complaint is Oakley lenses scratch too easily.

Awesome lenses. Before these lenses I had the ones that didn't have the vents. There is no comparison between the two. These lenses NEVER fog or ice up. No matter the weather, you will always see where you're going.

People say these are fallible because the anti-fog coating on the inside can get damaged. This is true. If you wipe them while they are wet they will smear. Don't do that and you are good. I find that the superior optics are worth the careful handling. Plus the availability of different lenses is second to none with Oakley.

I have several lens's for my two A-Frames (some of which may not be available now). Standard persimmon, VR-50, Fire, Chrome Iridium, and HI Yellow. Depending on conditions and lighting, each have their uses. Fro blue-bird days I prefer the Chrome Iridium or Fire. For overcast days, the VR50 or persimmon come in handy. For flat light, night, or poor snow conditions I highly recommend the HI Yellow; this lens is my single most used, as it makes the definition stand out in everything. The HI Yellow is almost like wearing headlights if you ride at night! I will say this: each person's eyes are different, so which lens works best for you is subjective; read all feedback before making a decision.

These A-Frame goggles and lenses are great for any light condition. Remember to change your lenses though; if you don't-you will miss out on the unique features of these lenses. High Intensity for low-light, Iridium for total sunlight. Makes the fog at Tremblant skiable!

Replacing these lens could make a grown man (or woman) cry with frustration. Instead of crying, be patient! You shall be rewarded with amazing clarity and vision. It helps to work on replacing the lens in front of a warm fire at home instead of a cold parking lot during an epic dump.

Replacing the lense in the A-Frame takes some brute force and stupidity. At least for the first couple of times. They are expensive, so use more force than stupidity. It gets easier as you interchange. The lenses are great. Asked by a Swiss mountain guide how I could ski when all others refused; I simply pulled off my A-frames and let him peer through. He placed his order that night.

After having an absolutly terrible time with getting a sunglass product, already paid for, from a Southern California on-line dealer, I was concerned with BackcountryStore.com making their delivery promises as well. They certaintly kept their promise of delivery and consequently I am very happy. I know that it was only one bad apple who caused my previous problems BUT it only takes one. When you are dealing with people miles away, your options of darkening their doors requires some amount of faith when buying on-line. I have learned my lesson, these guys can be trusted...

Fire A Frame Lens!!! All conditions gear!!!

Not only can I see in super flat light, but I think it is mid-day all day, even at 4:00pm on a snowy day.

I have the high intensity blue and fire iridium lens and think it’s the perfect combination. The fire lenses are great for cutting glare and look sweet for sunny days. When it’s dumping, I have not used a better lens than the high intensity blue lens. You can see every bump and hump with these bad boys. Only problem is they scratch really easily so be careful.

Haven't been to the slopes with them yet but have checked them out around here in different light conditions and they are going to work great! They are a little tricky to switch out but patience and persistence paid off. Buy them if you want to improve your on slope point of view.

This is an awesome lens for the conditions here in the East. I've used them on some cloudy and foggy days, as well as a few sunny days (I got lucky). They helped eliminate shadows and my depth perception was much better. They are not very dark for super sunny days, but overall an outstanding Eastern conditions lens.

Works great with low light and overcast days. I switch to the Fire lens on the Blue Bird days.

Works great in low or bad lighting and in fog. Not too bad in sunlight either, although it is a little bright. My first irridium lens and i can really tell the difference from my old persimmons lens.

This lens is remarkable in flat light. The light is too much on bright days.

The lenses are great..but if any of you have tried to change the lenses in these frames..u know this is a pain! I dont know why they made it so difficult to change these puppies but other then that the lenses are great. I just took them out in pretty flat light an they performed well. They also preform great in the intense sunlight of Telluride Colorado

Well, since I haven't actually used the new lenses yet, my review can only be partial. But, I think we all know that Oakley makes the goods! I actually had hard time getting the new lenses in the frames. It was so hard that I thought that Oakley may have changed the shape of the frame over the years; but alas, it was only me and after giving it the ole' collegiate try, I worked it out – thanks to the help/support of the Gear Guru at BCStore.com! Thanks! (I don't get paid to say this stuff – it’s actually true...)

Excellent Lens choice for those southern rockies sunny days. Thanks for the recommendation.

I've done a ton of night skiing and racing in the clear lens and it is by far the best lens for anything in the dark...crashing gates or freeriding at night in Japan...these things are awesome. The yellow lens is ok too for that (day flat light is best for the HI), but not nearly as good at night.

I do not know why everyone is having such a hard time replacing these. I just did one in under a minute. Just follow the directions and make sure all the slots are lined up and you're done.

I have the Hi-Intensity Yellow, and VR28 lenses and I think it's the perfect inexpensive combination.
The HI yellow's re great for the Northwest storms when you can't see anything, well with this lens you can.
The VR28 is excellent for sunshine and small clouds.
I will probably keep these lenses until i upgrade to crowbars.

I really like how versatile these lens are. It can be overcast or sunny, and still preform well. They are a cheap way to get your old A Frames to preform new like new again, expecially if you have tried to wipe out the inside of the lens (which is a bad thing to do).
I would like to add that the replacement lens are not practical to be changed out frequently. After the first time you replace them, you will not want to try it again.

I bought some A-frames with pink iridium lenses and i hated them in any light condition. I always had little pink
reflections dancing around my view and found it very distracting. I now have the H.I. pers. for lower lighting and recently got HI amber polarized which i think is going to be good in all lighting conditions

I own the A frames with the Hi polarized amber lens, and for living in the east these lenses are a sweet deal. They are very good for night and even when the snow is blowing they seem to brighten up everything. I have never had to change lenses since I bought these. I would have to say they are worth every penny!!

awesome lens awesome price! great color for all conditions
