Often staying up late will mend more vitamin A
If you are a night taxi driver, or you went home by car after often working overtime and staying up, two bunches of strong car lights opposite are taken over, make you dizzy for the moment. Then, the headlight speeds along and passes, yours is very pitch-dark in the twinkling of an eye at the moment, just resume normal vision several seconds later.
If just in a moment, some emergency has appeared in two fuzzy ones of yours above, there are large holes on the road, there are barriers, or the pedestrian wears, there won't be time to dodge, how serious the consequence is, it is a self-evident thing.
Though you complain in the heart the driver opposite lacks social morality, but it is very difficult for reality to change. Some drivers get used to driving the far-reaching headlamp frequently, someone returned one's own pet car loaded the xenon lamp of very high luminance with, let the light be more bright and more dazzling. In this case, you can change, have one's own eyes only - -Let it can adapt to light and shade change extremely of light, distinguish road surface the intersection of situation and time of ability shorten to the minimum losing as soon as possible.
However, if this bright hope wants to realize, need nutrition to offer the foundation. Because people's eyes are switched over from the visual system of strong light in the weak only visual system, need enough vitamin A to help. Once vitamin A is insufficient, will be lengthened when transferring from the light to dark and mere adaptation time, eyesight under being dark and mere will fail, it is the so-called nyctalopia when being serious. Although there are few people who really suffer from nyctalopia, walk to the night the driver, dark adaptation time lengthen itself, already is very much dangerous.
In fact, vitamin A is a kind of vitamin aptest to lack of compatriot, the slightly scarce situation is quite common too. I have seen many students, go downstairs when the light is dim and can not see clearly; Also see many drivers, does not see the pedestrian in the front clearly in the evening. To tell the truth, really worry for them! You know, complex reaction time is late half a second, the danger of the accident will be several times greater!
Come, say those turn on driver of headlight simply, it will be probably exactly the insufficient in supply person of vitamin A at a certain meaning. They see road surface of in the front clearly under ordinary the intersection of bus and the intersection of light and line, afraid of, it shakes the other side to be for a long time difficult to recover behind the eyes again, drive a vehicle will be often open the headlighting.
Besides driving clan, often facing toward the persons of the computer, television screen, eyes should all bear the light power change and test flickering frequently too. So, these people should increase the supply of vitamin A in the meal equally.
Help to supplement the food of vitamin A:
*Includes vitamin A - -Animal's liver, kidney, egg yolk, cheese, whole milk and full-cream yoghurt (especially AD milk) , many lipoprotein ocean fishes (the Coilia ectenes, fish of a lot of spring,etc. of autumn) that are suitable for roasting .
Warm suggestion:
1,The content of vitamin A of the defatted milk is very low, do not have at all in the albumen, do not almost have inside various meat.
2,Contain the fat, can absorb vitamin A in animal's food without the cooking of refueling itself.
*Includes and can transform into carrotene of vitamin A in the human body - -Various orange vegetables and fruits (carrot, the pumpkin, mango, orange, tangerine, papaya, yellow apricot,etc.) ,And various green leaves vegetables (spinach, cabbage mustard, green cauliflower, naked oats dish, the pakchoi, rape, crowndaisy chrysanthemum,etc.) .
Warm suggestion:
1,There is few carrotene in common fruits such as the apple, pear, peach, banana, grape, cherry, strawberry, water-melon,etc.. Content is few too in the red tomato, holy girl fruit.
2,The vegetables fruit does not need to add much oil and can absorb carrotene when cooking while coming. So long as vegetables cook, familiar with, with suck the oil food wipe out together while being other, the result of absorbing is very fine.
If food the above take seldom, work of eyes still very much if challenging Then, for the sake of safety, advise you to try not to go out to drive in the evening.
