If you're looking for a pair of futuristic glasses that have realistic, earth-shifting implications, check out these frames by 2AI Labs being tested by doctors right now (hmm? not who you were thinking?). They can make your veins glow so nurses can easily spot them, show a change in hemoglobin color to locate trauma…
If you're currently living on our pale blue dot, you should thank it for becoming inhabitable for us human folk. Specifically, you should look down and thank its mantle because scientists are saying that Earth's cooler mantle allowed it to develop oxygen. You know, that thing we breathe to live.
