葉黃素是什麼？
葉黃素是脂溶性色素，屬於類胡蘿蔔素（Carotenoids）家族，自然界中有600多種類胡蘿蔔素，其中30-50種是正常人類飲食的一部分。
類胡蘿蔔素可分為兩大類: 非極性胡蘿蔔素（carotenes，例如β-胡蘿蔔素及茄紅素）和極性葉黃素類（xanthophylls，例如葉黃素及玉米黃素）。
由於葉黃素的生物合成只發生在植物、藻類、細菌和某些真菌中，因此人類葉黃素的主要攝取取決於飲食或補充劑。
研究表明，飲食中葉黃素攝取量每增加10%，血清中葉黃素的濃度就會增加2%到4%
葉黃素在人體中主要分佈於眼睛（視網膜、杆狀外段、晶狀體）等人體其它部位，包括皮膚、子宮頸、大腦和乳房。
補充葉黃素或相關複方（每天10或20毫克，持續6個月以上）有助於提升黃斑色素密度（MPOD），並改善視敏度（visual acuity）及對比靈敏度（contrast sensitivity）。
血清葉黃素和玉米黃素濃度與骨骼質量無關，但黃斑色素密度（MPOD）與股骨近端和腰椎骨密度顯著相關。
暗適應（dark adaptation）是指在光照減少的情況下，眼睛對光線變得更加敏感的過程。
例如從一個光線充足的地方進入一個黑暗的區域(例如，去看電影)，一開始眼前會一片漆黑，但是一段時間後才開始看清楚
在臨床上，暗適應是一種測量視覺功能的方法，已經被證實為視網膜疾病的症狀之一（如黃斑變性、黃斑水腫、色素性視網膜炎、糖尿病和高血壓性視網膜病變），另外像是：維生素A缺乏、昡光、抽菸、老化、組織缺氧也都會造成暗適應能力降低。
兩則觀察型研究發現，黃斑色素濃度與暗適應有關，濃度較高者明顯有較佳的暗適應能力。
眩光失能（Disability glare）是指視覺範圍內，因高強度等未受控制的光所導致的短暫失去視覺精確度現象，眩光不僅容易造成眼睛疲勞，影響閱讀與學習，還可能引發交通事故。
另外，光刺激恢復（Photostress Recovery ）是指眼睛遭遇強光後需要一段時間才能恢復正常視覺，而老化及視細胞異常均可能導致恢復時間增加
幾則研究中發現，藉由補充葉黃素與玉米黃素（為期6-12個月，每日12 mg）能顯著增加黃斑色素（macular pigment ）密度，除了改善強光造成的短暫眩光失能現象，並有助於降低光刺激恢復所需時間。

What is Lutein?
Lutein is a fat-soluble pigment and belongs to the Carotenoids family. There are more than 600 carotenoids in nature, of which 30-50 are part of the normal human diet.
Carotenoids can be divided into two categories: non-polar carotenes (carotenes, such as β-carotene and lycopene) and polar luteins (xanthophylls, such as lutein and zeaxanthin).
Since the biosynthesis of lutein only occurs in plants, algae, bacteria and certain fungi, the main intake of lutein in humans depends on diet or supplements.
Studies have shown that for every 10% increase in the intake of lutein in the diet, the concentration of lutein in the serum will increase by 2% to 4%.
Lutein is mainly distributed in the eyes (retina, rod-shaped outer segment, lens) and other parts of the human body, including skin, cervix, brain and breast.
Supplementing lutein or related compounds (10 or 20 mg per day for more than 6 months) can help increase macular pigment density (MPOD), and improve visual acuity and contrast sensitivity.
Serum lutein and zeaxanthin concentrations have nothing to do with bone quality, but macular pigment density (MPOD) is significantly related to the bone mineral density of the proximal femur and lumbar spine.
Dark adaptation refers to the process by which the eyes become more sensitive to light when the light is reduced.
For example, when you enter a dark area from a well-lit place (for example, to go to a movie), it will be dark at first, but it will take a while to see clearly
Clinically, dark adaptation is a method of measuring visual function, which has been proven to be one of the symptoms of retinal diseases (such as macular degeneration, macular edema, retinitis pigmentosa, diabetes, and hypertensive retinopathy), in addition to: Vitamin A deficiency, bleakness, smoking, aging, and tissue hypoxia can also reduce dark adaptation.
Two observational studies have found that the concentration of macular pigment is related to dark adaptation, and the higher concentration obviously has better dark adaptation ability.
Disability glare refers to the short-term loss of visual accuracy caused by uncontrolled light such as high intensity within the visual range. Glare not only easily causes eye fatigue, affects reading and learning, and may also cause traffic accidents.
In addition, Photostress Recovery means that it takes a while for the eyes to return to normal vision after the eyes are exposed to strong light, and aging and visual cell abnormalities may cause the recovery time to increase.
Several studies have found that supplementation of lutein and zeaxanthin (12 mg per day for 6-12 months) can significantly increase the density of macular pigment, in addition to improving transient glare disability caused by strong light Phenomenon and help reduce the time required for light stimulation to recover.
