Eye is one of the important organs of the body because it helps a person of vision. To protect it for free from damage or disease, there are 7 ways you can do.

Structure and function of the eye to see it is not simple. It takes cooperation from some parts of the eye to produce an image that will be sent to the brain.

To maintain and protect the eye to stay healthy and avoid the disruption, there are 7 ways you can do as quoted by FoxNews:

1. Eating dark green leafy vegetables
Vegetables that have dark green leaves like spinach, broccoli or other vegetables contain lutein and zeaxanthin, two types of carotenoids that are known to reduce the risk of developing cataracts and vision impairment due to disturbances in the central retina.Try to eat two servings a day, for example, one serving of spinach at lunch and one serving of broccoli at dinner.

2. Consuming antioxidants
Foods such as berries, oranges, plums and cherries to help minimize damage caused by free radicals (such as from sunlight and pollution), as well as reduce the risk of hardening of the lens that can lead to cataracts. Consumption of antioxidants at least 2 servings a day.

3. Consuming omega-3 fatty acids
Evidence suggests that omega-3 fatty acids from certain fish such as salmon, halibut and tuna can protect the tear ducts, to protect the lens, minimizing dry eye and prevent cataracts. Consumption of 2-3 servings of fish a week and reducing red meat, because it allegedly could increase the risk of eye disorders in old age.

4. Eating carrots
This crisp vegetables contain beta-carotene compound, which is a carotenoid that can help keep the eyes to stay healthy. These compounds can also be found on the pumpkin.

5. Using goggles
UV rays are one of the main causes hardening of the lens, cataracts and decreased vision due to disturbances in the central retina. The use of glasses with dark lenses can filter up to 100 percent of UV rays when outdoors. If no glasses, can also use a hat to reduce exposure to UV rays.

6. Doing sports
Several studies have shown that aerobic exercise can reduce the pressure inside the eye, thereby reducing the risk of glaucoma. Sports that do can walk for 30 minutes 3 times a week, jogging, treadmill or taking a fitness class.

7. Consuming a multivitamin
National Eye Institute showed that the antioxidant vitamins C and E, vitamin B6 and B12, beta carotene and the minerals copper and zinc can slow the progression of visual impairment due to disturbances in the central retina and cataracts. Before taking supplements, better meet intake from natural ingredients first.
