Got the Fire iridium for those nice sunny bluebird days, the G30 for those changing days and the Clear ones for night skiing. They have all been solid for me, had some hard falls with them, and barely any scratches. I wear the crowbar with a Sweet Rambler helmet though, so the goggles might take a bigger beating when riding without a helmet, flying of the head etc..

I have grey polarized, and hi amber polarized. They are expensive lenses, but i love the clarity and field of view. I love the polarized tints too. The hi amber is probably the most rounded lens of any lens out there. I got the grey as a spring ultra bright day lens. The choice is yours, check out oakley.com they have a cool lens tint thing you can see what the tints look like.

I've ridden the Crowbars in HI Yellow, HI Persimmon and Blue Iridium. All are amazing lenses for their respective conditions.
The HI Yellow's are great for overcast, snowy, foggy, rainy and night conditions. (Basically, the HI Yellow will slay any sort of low-light conditions.) The blue reflective coating makes them look better than a standard yellow lens as well.
The HI Persimmon is a great all-round lens. They're not perfect for bluebird days, but you won't squint too much. They're not perfect for night riding, but you wont' really strain your eyes for terrain clarity. They are, however, perfect for everything in between.
The Blue Iridium are a fantastic bright conditions lens. They are more versatile than Black Iridium or Fire Iridium, which are exceptional for bluebird but more or less one trick ponies for sunny days. The Blue Iridiums are a bit more versatile if the clouds roll in.
Don't get a lens just because it looks cool, and it will pay off for you with perfect clarity.

WOW-EE-WOW-WOW!...its just one lens! how can it do so much!!! it takes the blinding sun factor out of bluebird days...increases contrast and definition in fog, snowstorms, and overcast...and at night it lights up the mountian like a bulb! (ok that last one is exagerrating but it works great at night) ONLY COMPLAINT is that it is very see-thru from the outside, and im all super-ficiall like that so i dont like see thru lenses...but for a see thru lense it has a cool, blue semi-reflective finish

persimmon lens is ok, and thats it...it doesnt excell in any condition but doesnt lack in any either, except one...ill just go over the spectrum -BRIGHT SUN: stay away! this is not dark enough by far, after a bluebird day everything looked pink...i immediately went and got a darker lens -STORM/SNOW/FOG: contrast is laughable but at least the lens is light enough to see in those condtions, the mountain wont look like its shrouded in shadow -OVERCAST: contrast sucks again, but the shade of the lens is good for overcast -NIGHT: hard to decipher anything different, ice/snow/guy dressed in white/jumps, its all hard to see cuz theres no definintion or contrast, but at least the shade is light enought to see at night BOTTOM LINE: this lens kinda sucks, but it will work if your pinching pennys and need an all around lens, just stay away from the sun and be prepared for everything to turn orange :-)

I shred the park under the lights sometimes, so i got the clear, works great, and so fairly easy to change.

The hi yellow are awesome for the low light foggy or snowy days. I just brightens up everything.

I was forced to buy a new pair of goggles for this year after a new puppy to a liking to my Dragons from last year. What I didnt like about those (small lens, low peripherals) is what drove the Oakley purchase. These are awesome, huge viewing area fit well with my helmet (Giro 9 audio) and good style. I went with the HI persimmon, was going to wait for an end of year sale to pick up a HI yellow lens, but found a HI yellow pair on Steep n Cheap and couldn't wait so now I have two pair, oh darn. Oakley has always been at the top of the heap in terms of quality and customer service and nothing has changed.

These lenses are amazing. H.I Amber Polarized for the bluebird days and then H.I Persimmon when the sun disappears...

This is just a link to the Oakley web site... if you go to the bottom of the page and click on the "lens tints" tab, it gives you a very good description of each lens tint and what conditions they perform best in.

I have the HI Persimmon, the Persimmon, and the Fire Iridium lenses. The Fires are perfect for blue bird days No squinting with those bad boys. the HI Persimmons are amazing for everything between night, and overcast/snowy days. They are probably the most versatile lens I have had for my Oakleys. The Persimmons I mainly use for powder days in the trees, because I like to cut things close with the trees, and sometimes close is a little bit too close resulting in a smack in the face by a tree branch. They are a good cheap lens that I am not afraid to thrash. They also seem to be good for mild lighting conditions. Oakley has the best eye wear in my opinion, and I am looking forward to using my lenses again next season... But if you are looking for a goggle, you should go with Oakley. These lenses are great for the areas that they are specified in, for sure.

Absolutely the best lens ever. Perfect for low light conditions.

Hi Yellow has an 81% light transmission. Clear is 93%. It's a huge difference to me in white out conditions. The Hi-yellow lenses drove me nuts.

Maybe the yellow tint is better at picking up contrast but it's a major reduction in visibility compared to the naked eye. Obviously the blowing snow makes the naked eye bit problematic hence the clear lens.

Even without direct sun, if the cloud cover thins to the point where brightness increases then it can be too bright for the clears. Often this is only momentary so I just suck it up rather than switch in a diff lens.

I have a set of Fire Iridiums for sunny days but I usually wear sunglasses.

The lens optics are great, however the lens split after 1 fall. Oakley didn't stand behind thier product and honor the warranty, so I had to buy the replacement. Love the optics, but am hugely disappointed in oakley.

This lens is killer. I rode the other day (bluebird) and the Blue Iridium lens was really great. Not only was the lens dark enough for the conditions, it was versatile enough to give me definition in the shady spots. Crowbars are my favorite goggle ever.

HI persimmon: prob the best overall/all-around lens oakley makes. PERFECT for overcast days which the east coast is infamous for, and still holds up to sunlight without blinding you (like the HI yellow or pink iridium would) and still brings out the light during night skiing (not extreme low light, but as long as your resort has some spotlights, which most do, you'll be fine. If you can only have one lens...... HI PERSIMMON!

Awesome lens. Replaced set of polarized Carrera's that I've had for 12 years. Works well in all conditions, but best suited for sunny days. I don't recommend this lens for anyone who doesn't take care of their gear as the surface looks like it will scratch easily and replacement are mucho $$$$$. I keep the goggles in a hard case when traveling.

Picked up the fire for my Crowbars, already had the Pink Iridium so I needed to pick up a darker lens for those crazy bright days. All I can say is that these are fantastic. Easy to change in and out and high quality lens. Great buy.

Hi yellow/blue I like this color and it seems to get used the most. It's great during heavy dumps or a bit of fog on the peak. Definitley for lower light it lets in just about as much light as a clear lens. I find that sometimes they replace easy and other times it's a pain in the butt.

great vision to them, i own the Fire (absolutely sick for those blue bird days) and the pink iridium which just kills it on overcast days. best two lens' for multi-condition days!

they were pretty easy to get in. i enjoy the lens color. ive owned alot of oakleys and ill keep going with oakley

Oakley makes great vision products, and these were no exception.

Nuff said.

Steve

you can by this lense at any shop that salls the goggels for 160 with no % off and u can all was wangle 10% off making it less then wat these guys are selling it for

these lenses are great i recomend the blue iridium but if you are short on money order the gr28 lens they are the same tint

Just be sure its sunny out before you pop these into your goggles.

great for flatlight and super sunny dayz are tolerable

I just love the look of this lens. Gets a lot of glances in the lift line. A little too bright for those sunny days, but perfect for greybird and those days when it dumps. Peripheral vision is fantastic and they don't fog up very easily.
