Scientific sunblock: new sunglasses use pixels to block the sun

bright sunlight glare on a wet road or a white snow field? Would the sunglasses be completely dark? There are sometimes where the bright glare is very bright in a large area.

Interesting product, but expensive.

I've seen non-prescription designer sunglasses, or just glasses/sunglasses FRAMES sell for that much (I wear glasses). Given, for what amounts to a few grams of weight, unless it's pure gold, I shouldn't be paying $300+ without lenses.

These are expensive, but for a good reason, it's new and interesting tech. Not some corp trying to r@pe it's customer's wallets for the bottom line (yet)

It is cool tech for a science fair, but in the real world it has no practical value beyond being a gee wizz product that people will brag about owning because they have the money to afford them.
