For people who spend most time of the day staring at computer screens,
their eyes are the most vulnerable to be overworked. Without being protected,
eye health may gradually be deteriorated. Following vitamin supplements,
however, can help solve the problem.
Vitamin A
Retinol is the chemical name of Vitamin A. The discovery of
vitamin A stemmed from a research dating back to 1906, this is also the first vitamin
to be discovered. In our bodies, vitamin A is engaged in maintenance of good
vision, preservation of columnar epithelial cells’ functions. One of the first
pathological manifestations of deficiency in vitamin A is visual impairment,
which includes night blindness, and dry eye disease.
Vitamin A-rich foods
Vitamin A can be found in many foods: Liver, egg yolks, butter,
milk, cheese, water convolvulus, sweet leaf bush, green mustards, pumpkins,
carrots, mangoes, etc.
However, as being fat-soluble substance, excessive amount of
vitamin A absorbed through foods are more difficult to be discharged against
with those of other water-soluble vitamins such as vitamin B and vitamin C.
Consequently, overdose of vitamin A can be poisonous. Its
complications range from nausea, jaundice (yellow skin), allergies, anorexia,
vomiting, blurred vision, headache, muscle and stomach damage, drowsiness, and
mood changes.
β-carotene
Beta carotene is a tenpin. It is one in a group of 600 yellow,
orange or slightly red colored pigments called carotenoids that have been found
in nature.
β-carotene is mostly
available in vegetables but never exists in
animals and foods of animal origin. Beta carotene is also a precursor of
vitamin A, however, it has a wider range of biological applications than those
of vitamin A.
β-carotene-rich sources of foods include green and yellow
vegetables, orange colored fruits such as carrots, spinach, lettuce, potatoes,
sweet-potatoes, broccoli, red water melon and etc.
Vitamin C
Vitamin C is also
beneficial to eye health. People
having vitamin C-rich diets can reduce the risks of cataract formation and
retinal degradation. In addition, this antioxidant also slows down cataract
progress and improve vision.
Cherry is the greatest source of vitamin C, followed by guava, chili,
yellow apricots, broccoli, strawberry, oranges,
kale, cauliflower, kiwi and etc.
