FDA Approves First Contact Lenses That Turn Dark In Bright Sunlight (interestingengineering.com)
The first photochromic contact lenses have been approved by the FDA. "A unique additive will automatically darken the lenses when they're exposed to bright light," reports Interesting Engineering, citing a FDA statement. "The lenses will clear up whenever they're back in normal or darker lighting conditions." From the report: "This contact lens is the first of its kind to incorporate the same technology that is used in eyeglasses that automatically darken in the sun," said Malvina Eydelman. Eydelman serves as director of the division of ophthalmic, and ear, nose and throat devices at the FDA's Center for Devices and Radiological Health. The FDA approved the technology after extensive trials and clinical studies. One study had 24 wearers use the contacts while driving in both daytime and nighttime settings. The FDA found that there were no problems with driving performance or issues with vision while wearing those contact lenses. In total, over 1,000 patients were involved in the various studies conducted by the FDA. According to current plans, these photochromic lenses should be available for those needing them by the first half of 2019.
My guess is that this is a Russian troll too, or an American moron. What the left seem to not realize is that there is something far more valuable for Russia, as a competitor to the US, than a friendly president... it's the whole of the US at each other's throats and the collapse of our political system. That my friends is the long term destabilization that will have Russia back on top on the international arena. They don't care about Trump... they'd much rather we were fighting each other. And we're playing into their hands.
