Light and The Eyes

Anatomy of the Human Eye
The eyes are organs of light, the more natural, full-spectrum light you give your eyes, the more healthy your eyes and you will be. According to research scientist, sunlight has many surprising health benefits to humans.
Light entering the eyes is utilized by the body in two ways:
1. Light energy travels to the visual cortex, where a picture of the world is created,
2. Light energy travels to the hypothalamus, which sends messages to the pineal and pituitary glands. Together, these organs and glands regulate many functions of our minds and body.
Natural, full-spectrum light from the sun is essential to our health. Be outdoors in natural lighting at least one hour per day. Even indirect sunlight on cloudy days is beneficial. If you are over-sensitive to bright light, do closed-eyelid sunning to rebuild your light tolerance. If you have been indoors for a long time, and then go outside into the bright light, wait a few moments to adapt to the bright light. Sunning with closed eyelids, even for a few seconds, can help you adapt quickly to bright light. If the sunlight is still too bright, wear a hat, not sunglasses. Notice that most professional tennis players, and many other athletes do not wear sunglasses, even when looking into the bright sky. If you feel you must use sunglasses, wear ones that are 'neutral-gray' and with the least tint you can comfortably get by with. If possible, use maximum UV-transmitting sunglasses. Wear sunglasses only if you consider them necessary for certain situations. Worn for short periods of time, sunglasses are not harmful. Do not become addicted to sunglasses.
People who live in a location where there is bright light have naturally adapted to that light. For example, people who live in areas where there is a lot of snow do not need sunglasses on a regular basis -- they have adapted to the brightness of the snow. Due to the speed of modern transportation, people can travel quickly to a new location with very different light. For example, if you live in San Francisco and drive to the mountains to go skiing, suddenly there is bright glare from the snow, to which you are not accustomed. You may want to wear sunglasses for a short time. When returning to San Francisco, do not continue to wear the sunglasses as a habit.
When indoors, use the best full-spectrum lighting possible. Lights that provide continuous mid and near UV light are preferred. Natural vision students who have installed full-spectrum lights have been very happy with them. They really do make a difference to your health.
Glamour is a motivation for some people to wear glasses. Sometimes children, who do not need prescription glasses, want to wear glasses to look fashionable. This fashion will be at the cost of interfering with the visual system and health!
To control night glare for drivers, special eyeglasses, where only the left part of both lenses is tinted dark as in sunglasses, were invented and patented by a number of individuals to provide a useful control of oncoming cars' lights glare. During the day, direct glare from the sun and reflections off the road or off a car's engine hood may be controlled with the aid of sunglasses.
One of the greatest dangers in wearing sunglasses as a habit is that the individual can become addicted to darkness. By not allowing the eyes to experience normal sunlight, a person can become more sensitive to the bright outdoor light. One then becomes dependent upon the dark sunglasses as a necessary crutch. This scenario is quite similar to becoming more dependent upon prescription sunglasses or glasses -- the more you use them, the more you will need to use them.
