Here is what I did to solve the issue and I have to say it is a perfect solution. I can't take credit for this because I was led to the idea from another post where someone mounted their readers inside the
goggles. Here is what you will need, Carson Optical VisorMag these come in 1.75x(+3.00 Diopters), 2.0x (+4.00 Diopters) and 2.25x (+5.00 Diopters), they range in price (current) from $6.89 to $8.99 NOT in order from lowest x to highest x.

If you need lower they also make them in a different version called Carson Clip-and-Flip which come in 1.5x (+2.25 Diopters), the part you will detach is exactly the same so just order the cheapest you can find in the power you need them in. The lens easily detaches from the mount which you will not need but you can save if you also want to use them as designed since you are not altering the lens in any way other than a small piece of Velcro. I bought all 3 of the VisorMag versions as I didn't know which one I would want. I was using 1.75 readers and as it turned out the 1.75x (+3.00 Diopters) are the ones that looked perfect so I guess they do cross over to readers by power. For mounting I first tried a small piece of Velcro but it didn't feel like it was getting the best hold because the Velcro didn't seem thick enough. I then used a piece of what is called 3M Dual Lock tape that came with my Pennsylvania Turnpike EZ-Pass to mount it to the windshield. This can also be bought on Amazon and this link looks like the best price for the amount you will need.

This type of Velcro type fastener is a little thicker and holds much better than standard Velcro and allows the lens to seat perfectly on the
goggles. A small piece just the size of the cross bar on the lens is all you need and another small piece between the lens on the
goggles. Due to the plastic piece being clear that was used to mount the lens to the original clip it still allows the
goggles to shut off and doesn't interfere with the proximity sensor. Therefor there is no need to remove it and it provides for a nice grip for removing the lens from the
goggles, this is almost like they were made for these
goggles. I am a tinker type of guy and I pretty much mess with everything and find ways to improve on them and other than mounting different type of Velcro I can't really find anything I would change on this setup that wouldn't cause you to alter the
goggles by mounting the lens more permanently by affixing the lens or mount by screwing or gluing in some way. These also come with the case included which just fits the lens only which is perfect since you don't use the clip mount. I'm not even going to bother sending the other 2 sets back because they do have use as originally designed and even buying all 3 sets I'm still under $30 to get perfect vision on my
goggles. I spent $449 so the extra money is well spent. Most should be under right around $12 for the Dual Lock tape (which I highly recommend over standard Velcro for strength of hold, quality of hold and positioning and ease of removal) and the Carson diopters. Feel free to ask any questions. This setup is much better than wearing readers that when I lifted the
goggles I had to remove to see the Mavic, then put the readers back on before lowering the
goggles. Here are a few pics of the setup.
