Here are the two types of lights used in the classroom study.

2
00:00:09.680 --> 00:00:15.900
The new radiation-shielded full-spectrum fluorescent light results in full muscle strength.

3
00:00:16.940 --> 00:00:23.560
But now, moving over to the standard type of fluorescent fixture, the muscle is unbelievably

4
00:00:23.560 --> 00:00:45.520
weak. Most sunglasses and even ordinary eyeglasses cause muscle weakness. But full-spectrum lenses,

5
00:00:45.760 --> 00:00:52.300
either clear or full-spectrum neutral gray sunglasses, do not cause any loss of muscle

6
00:00:52.300 --> 00:00:58.500
strength. Now to show that the loss of muscle strength was not due to fatigue,

7
00:00:59.020 --> 00:01:03.500
once more back to the radiation-shielded full-spectrum lights.
