I recently got some night driving glasses that make the wptld look very yellow. As soon as I put them on during the day my eyes completely relaxed and I became calm inside. Like some un seen stress was released. They became so therapeutic I put them in for awhile now every day. I remember when the natural sunlight ight was more yellow than white. At least it seems to me n it was and now its this silvery light we live under. I may be just imagining it, but those glasses made me remember something more natural about the sun light than what we now seem to have. Im not kidding when Insay i get some instant relief when I put them on.
