However , if the sun is a little bit brighter and a little bit higher in the sky , sometimes it could be painful to look at . So the way to get this sunlight viewing early in the day is to look toward the sun . If it's too bright to look at directly , well , then don't do that .
But let's say it's a very clear day and I can see where the sun is . I do not need to stare directly into the sun . If it's very low in the sky , I might do that because it's not going to be very painful to my eyes .
But we can give some general guidelines in general on a clear day , meaning no cloud cover or minimal cloud cover . You want to get this sunlight exposure to your eyes for about five minutes or so . Could be three minutes , one day , could be seven minutes the next day , about five minutes on a day where there's cloud cover .
In fact , I encourage you to blink whenever you feel the impulse to blink , never look at any light sunlight or otherwise , that's so bright that it's painful to look at because you can damage your eyes . But for this morning sunlight viewing , it's best to not wear sunglasses . That's right to not wear sunglasses .
If your goal is to be awake , if you wake up at four in the morning and you need to be awake , well , then turn on artificial lights once the sun is out . However , once the sun has risen , then you still want to get outside and view sunlight . Some of you will wake up before the sun comes out .
