Hi all,
I recently picked up some orange UV ski goggles which are mostly orange but rather interestingly make the greens pop, I tried to replicate this with an orange filter but i guess unsurprisingly it pretty much makes everything orange.

The effect of the glasses seems to increase sharpness and contrast and the greens are different grass is more emerald green and horse chestnuts a lime green. Makes everything a bit brighter too.

I managed to find on Amazon a pair of laser safety glasses which is designed to filter UV and blue light very similar to the first pair. It's a polycarbonate material but now I need to mod this to fit a lens.

Any ideas?

No ideas, but it will be very interesting to see the result,
considering one's mind adjusts for what the eye sees through the glasses.

I would not anticipate much variation from the orange filter.

I'd hold the glasses in front of the lens to see what that portion of the image results in creating before going to all that work.

The best idea i have come up with so far is a cokin filter adapter good bit of surface for taping glueing the lens.
I think making a screw in filter would be quite tricky.

You could start with an old screw-in filter and remove the filter glass. Use the removed glass as a template for cutting your orange lens. Then install the new lens in the filter frame.

Experimenting is how we make progress. I've experimented with holding sunglasses - polarized and regular - in front of the lens.

Find a press on plastic lid the slightly larger than your lens circumference. Cut out the center and attach your filter material to the remaining edges. More costly but neater, and more practical solution buy the proper drop in gel filter holder and cut your material accordingly. All the large camera dealers carry them.

Though, the two such folders I have are for holding thin gel and plastic filters, not thicker glass filters, even if square and rim or frameless. Goggle glass is probably not onion skin thin.

Personally I have tried placing colored contrast filters that I have had since my film days over lenses on my digital camera. Nothing useful came from this. About as horrible as a similar filter used with Kodachrome Film. The only "pigmented" filters I use for digital photography are Infrared passing ones for IR photography using an non-converted digital camera. I also have a IR converted cameras where the needed filters are installed over the sensor directly. Digital cameras seem to go crazy when trying to white balance non-RGB data. Note, a yellow filter is minus blue light. Magenta minus green, and so forth. Not sure that your laser glasses are even removing polarized light like sky glasses are. There is something else going on that I do not know. But I know many even low-power laser light can damage your eyes as well as digital cameras.

The effects you describe sounds just like a didymium "enhancing" filter, which you can buy ready for camera use. Its a rare earth filter. Your ordinary orange colored glass filter is in no way similar.

Didymium eyewear, with perscription or plain lenses, is also available, and you apparently have an example in hand.

The effects are fairly reliable in daylight, especially in sunny conditions. Artificial lighting results are far less predictable.

So in essence this is like the coating put on camera lenses, rare earth elements and others, but thicker. For photographic use, why not just use old school vintage film lenses with tons of multi coating that give high contrast and saturation without supplemental filters? Seems even state of the art sun glasses and camera optics are apples and oranges.

What you write does not seem to me to be related to didymium rare earth filters. Enhancing filters are a bit mysterious but heres some quick examples by phone camera:
