Taking vitamin-rich foods can improve eye health in general. But the reality is we can not get all the vitamins we need from food alone.
Current farming practices and soil nutrient reduction produce fruits and vegetables containing notably decreased amount of minerals and vitamins. This led to the production of vitamins for eye health which gains increased availability for consumers nowadays around the world.
Vitamins for eye health can be bought over the counter unless a person needs a high dosage of these vitamins to cure any existing eye problem. They may be taken one to four times daily depending on the amount of vitamins and minerals that they contain. When choosing the right vitamins, it is best to check on the vitamin and mineral composition of the brand that you are considering.
Here is a list of vitamins and minerals which should be present in eye vitamins alongside the eye problems that they prevent.
Vitamin A, C and E
Vitamins A, C and E are anti-oxidant vitamins which can be found in dried apricots, oranges, kiwis, nuts, broccoli, mangoes, blueberries, papayas, grapefruit, tomatoes, peppers, raw carrots, green beans, green peas, brussel sprouts, green leafy vegetables, eggs and dairy products. Vitamin A provides good night vision and impedes possibilities of cataracts. Vitamin C helps prevent the accumulation and crystallization of foreign molecules in the eyes which can cause blurred vision. Lastly, Vitamin E plays a vital role in reducing the advancement of a very serious progressive eye disease called macular degeneration which entails limited vision and total blindness
Lutein & Zeaxanthin
According to studies, taking in "carotenoids" such as lutein and zeaxanthin provide lower risks of having age-related macular degeneration or AMD. Although there already tablets and capsules in drugstores that contain and possess the names of these "carotenoids", the natural sources of these are sweet peppers, yellow peppers, corn, lettuce, spinach, kale and bilberries.
Omega 3 Fatty Acids
Research from Harvard Medical School found that taking omega 3 oils reduces the chance of getting dry eyes. Omega 3 oil is contained in fish oil supplements. Taking 3 to 6 grams of it daily would do the trick.
While these vitamins for eye health are readily available with out a prescription, it is recommended that you consult an eye specialist first. There are some formulas or mineral and vitamin combinations present in some eye vitamins that may cause certain diseases if a proper health check is not done before taking them. Presence of Vitamin A in for one affects the health condition of smokers according to a study. After a visit to a physician, it is best to compare the eye vitamins to ensure that they could meet your eye health needs. Read More: http://tinyurl.com/m2a4m4g
