Can someone tell me how, or if this is difficult to do?

I wanted to post a link, but it does not work anymore...

But changing the lens is very easy, just do it somewhere stable where you can see where the little parts (screws and washers go so you dont loose them)

Oh, when I went to have some lenses made for my juliets at one place (I think Lenscrafters) they told me they don't mess with juliets because there pressurized and it's hard to change the lenses or something stupid, like they tried once before except that the glasses got ruined because they tried changing the lenses. That's why I was asking

You can take out the lense. It's easy. I took out the lenses on my Penny's and it took 10 mins. Unscrew the 2 screws with a T6. Just be patient when you remove the lenses and apply very little force on the lenses to prevent them from breaking. Slip in the new lenses and screw back on the screws. Oh and I'd suggest wearing latex gloves when handling the lenses to prevent fingerprints. Simple! Good luck. BTW, Lenscrafters suck.

Be very careful when undoing the screws they tend to strip easily, has happened to me twice

Whenever I do not have available latex gloves, I handled the lens using the pouch. I sort of cover the lens in both sides with the pouch, making sure that my fingers will not touch the lens. I took extra care in applying pressure to the lens when putting it in the frame, same care in opening the frame a little bit for the lens to slide in easily. I find it easier to start inserting the lens near the nose bridge and work towards the hinge. Same way when removing the lens.

What do you do if the screws get striped and you can't get it out?

Hey Ruby_Penny... Use a T7 screwdriver

Which is the correct screwdriver to use? T6 or T7?
Also, can these be easily found in all hardware stores?

Yeah, I once got a t6 on ebay, to replace the screen on my p900, and it was a complete waste. I do believe my swiss army cybertool 41 has one though. Haven't exactly had the urge to test it on the Juliets though.

Like others have said... just watch you don't strip the screw and everthing else... is easy.

Not sure whether this would help, but this is the instruction from Oakley which comes with the replacement lenses kit. it is simple to understand and follow.

As mentioned by numerous others, do take special care when loosening / tightening the screws.....if not the your next thread would be "Busted Juliet screw Head'....i am sure most of us out there with juliets and have tired changing the lenses yrself would have plenty to say to that...not meant to scare anyone though...just a word of caution...

cheers

do buy a good quality T6 driver(they're usually USD 5 and upwards, i got mine USD 7).

trust me, it makes a whole difference. for sure it doesn't strip the screws as much as the cheapo ones which i threw away.

Ive had the screw strip using both cheapo and high quality drivers. i think the problem is the screws themselves being soft

Thay sell good ones a Sears & you can buy them individually

I wonder if I sent those loose screw to Oakley, will they replece new one for me???

Does the X-Metal frame have a dip the lenses go into? Or is it more of a groove that the lenses sit in and are tightened onto by the screws from the frame?
