My eyesight is okay but not too good in the dark. K37 has great visibility at night.
When I had the k37 wraparound heat rejection was good, noticeably better than the 10 year old magic tint it replaced. Now, my current car with k37 in the windshield and k28 in the windows is ok as well. Its a corolla and the aircon is very good, so I think that contributes a lot more than the tint. Just an observation, the tint might reject UV and some heat from coming in but the car still gets hot when parked. During 40+ degree days in the noon time you still feel heat from the windshield and the windows, even with the AC running.
