I have an old pair of sunglasses made to correct vision, has polarizing filter layer + color filter (more like green/yellow) and it give the visual impression of lots of contrast, colorful without haze. I have seen ND filters, ND grad filters, CPL filters, and B&W color filters for photography, but never seen any filter optimized for photography in harsh summer light.

Ah ah, I've tried step 1 already (with old glasses) but those glasses aren't flat, and they are too small to cover the front of the lens, not an easy task.

Yes, that's what I see in the skies with a CPL on the camera on a wide angle lens. I suppose my two eyes behind the sunglasses are also wide angle but I do not seen a the blue sky fading on the corners like it is with the camera.
