Vitamin A and beta-carotene are most important for overall prevention of vision loss and healthy promotion of the eye. But what makes the two so special? Let’s have a detailed look.
- Vitamin A
Vitamin A isn’t just one thing but a whole group of fat-soluble compounds available in two forms in the food we eat namely: performed vitamin A and provitamin A carotenoids. As for performed vitamin A, animal produces such as fish, liver, meat and dairy sources are great sources whereas provitamin can be obtained from leafy green vegetables, bright coloured vegetables such as purple, orange and yellow, fruits, tomato products and vegetable oils.
One of the biggest benefits of vitamin A for the eyes is its capability to fight macular degeneration and vision loss. Some other advantages are immune system boosters, soothing of the eye inflammation and lowers the risk of eye infection development.
Yet another provitamin carotenoid is beta-carotene which is responsible to give many vegetables their particular shades like orange-red for carrots and various colours of peppers. Beta-carotene however can only be obtained from fruits and vegetables unlike animal products for vitamin A. Some other great sources include spinach, romaine lettuce, dark leafy greens, cantaloupe, apricots, squash and sweet potatoes.
In today’s world, dominated by digital devices and overexposure to blue light which has only brought pain and vision reduction to the eyes, beta-carotene reduces oxidative stress put on to the eyes via this blue light. Human body is capable to convert beta-carotene into vitamin A which means the benefits are quire similar to the overall immune system and the eyes, especially when it comes to sharpen the vision and making it powerful to see clearly during night time.
The Appropriate Consumption Amount
Prescribed multivitamin and supplements are an effective way for the body to receive essential vitamins that are usually missing from the normal diet however, overdose of anything can have adverse health effects so it’s always better to consult a doctor before proceeding. It’s always best to receive a healthy daily dose via normal food. This is especially important for those who’ve been recommended or recently have had their vitrectomy surgery performed for better healing and safe recovery.
Vitamin A also shields the eye surface (cornea) which is crucial for clear and good vision. Medical research has concluded that vitamin A eye drops are effective for dry eye treatment which, has been proved by a comprehensive medical research. One such study also revealed that these vitamin A eyedrops are far more effective against dry eye syndrome than any other more expensive form of treatment. These are also recommended for treating a particular type of swelling in the eye known as the superior limbic keratoconjunctivitis.
Combination of vitamin A and other antioxidants is quite effective against vision loss from Age-Related Macular Degeneration (ARMD). Combining vitamin A with lutein helps in improving longevity of vision sharpness and visibility among the people suffering from retinitis pigmentosa.
Even after all the benefits, we always prefer recommending with the eyecare specialist before taking any drug or even natural food for improvement of vision and eye health.
