Oh yeah shades are the biggest downgrade in terms of nub items that came back from HH, PLUS their description is a complete lie, they do not, infact, hide your eyeballs...at all.
This also has a lot to do with the dithering effect the game uses for transparencies like the waterfalls and the glass objects (like brain jars, or in this case, the glasses). This effect varies a lot depending on your zoom length, but I can guarantee that if you zoom out fully on a 1366 x 768 resolution, the effect looks absolutely horrid on EVERYTHING. Here is a comparison between fully zoomed out sunglasses (aka normal person mode) vs fully zoomed in sunglasses (ie myopia mode)

(it's not supposed to literally be a 4x4 split of blocks and nothing)

(Much more like glass)
This effect is basically trying to simulate dithering or screentone, but it scales badly depending on the display. I know I went on a tangent, but it is one of those things that make the sunglasses even worse than they are already.
I do really wish they were just black, there is a reason these were the most used cosmetic in HH but arguably one of the least used items here. It just looks bad, and the glass effect should've only been used on the nerd glasses, WHICH FUN FACT, HIDES YOUR EYES BETTER THAN THE ITEM THAT'S SUPPOSED TO DO THAT!
