Do+Vegetables+Increase+Vision

__**Can Carrots or any Vegetables Improve Vision?**__ A huge eye study was done in Australia examining the link between increased vitamin A intake and deteriorating vision in older people. They found that people who reported having poor eyesight ate more carrots – just as their mothers had told them – to improve their eyesight but it didn't help. There still is some truth to the old wives' tale regarding carrots and eyesight, such as:
 * __Topic__**
 * a diet with sufficient vitamin A, iron and other provitamins (substances that our bodies can convert into vitamins) is vital for eye health.
 * There are two types of vitamin A: retinoids and carotenoids

__**Light/Optics**__ This topic relates to optics because it has to do with eyes and sight. The only way we are able to see is with our eyes, we have to keep ours eyes healthy so we are able to maintain good eye sight.

Eating carrots, and other sources of vitamin A, can improve vision if you are deficient in vitamin A. Most vision loss is caused by age-related deterioration **not** a dietary deficiency. This is why their eyesight didn't improve regardless of how many carrots they chomped on.

Carrots, broccoli, sweet potatoes, pumpkin and dark-green leafy vegetables all contain beta-carotene, a potent carotenoid. But how much gets converted depends on how much vitamin A you already have in your body – in other words, your body doesn't make vitamin A if you don't need it.Carrots and many other foods do contain beta-carotene, which metabolizes into Vitamin A and everyone agrees that is essential for **//maintaining//** eye health, but it does **//not improve//** it.
