Unless they tinted the glass blue I guess but even then you would either have a permanent night or permanent full on solar hyper radiation. Like how would lighting that even work?

Assuming the ring is orbiting the sun, you just tilt the ring a few degrees, depending on the width of the ring. At one point in it's rotation, the sun would be nearly directly below your feet and your part of the ring would be unlighted. At such times, the opposite side of the ring would be in sunlight shining from behind/beneath you. That part of the ring would likely appear as a glowing ribbon across the night sky and provide light like the full moon does on Earth. As the ring rotates you to the day side, the sun would appear to rise from over the edge of the ring wall and shine down on your part of the ring. At noon, the sun would be over head, just a few degrees to one side of the opposite side of the ring, which would likely be invisible in the glare.

Needless to say, the ring base and glass would need to block the most harmful rays of sunlight for that to work.
