Some take this a step further and gaze at the sun. It's called "sun-gazing" and the proponents are thoroughly convinced of its effects. One man, Hira Manek, says he lives off sun-gazing. Some say it has cured their vision. The basic idea is that you gaze at the sun for ~10 seconds the first day, then up another 10 seconds next day, and so on... you eventually grow upwards to 40m. Having tried it a few times, I would attest to its beneficence, but don't expect any serious scientific study backing it. It's very, very new-age. Also, don't go blaming me if you hurt your eyes. Do your research on it.
