No one can deny the importance of eyes. With good vision, one can enjoy the brightness and colorfulness of the world. However, seldom do people pay any attention to their eyes and they suffer from some eye problems that might be caused by various factors.
Some studies have discloses that the population of eye problem-struck people will be over 50million within 10years. In particular, people who are over 65 run much higher risk of getting those problems. And over half of those who are over 80 will become blind.
Generally, eye problems will lead to vision decline and some symptoms will also arise in the meantime. Cataracts, eye infections, redness, etc. are some of the commonest eye problems.
Fortunately, with the development in the field of eye health, more and more people have noticed the important relation between eye health and nutrition. And some nutritional foods and supplements are brought to the market. In addition to those well-known nutrients that can help enhance people’s vision, some other new nutrients have also been found, such as lutein, zexanthin, etc. And all those new nutrients are helpful for people’s eye health.
Lutein can be found in some leafy vegetables. And it is an inborn part of macula. This nutrient is believed to be able to filter out any harmful radiations from the sunlight.
Macular is a vital part of eyes and it plays crucial role in maintaining people’s vision.
In addition to lutien, zexanthin is another new nutrient that is also very important for people’s eye health.
Some studies have disclosed that harmful rays, like UV radiation, are some of the major causes for cataracts. And lutein and zexanthin are just the important substances that can help block out such rays. To some extent, the two nutrients are much effective in preventing people’s vision from being injured by UV rays than other known nutrients, like Vitamin E.
Other studies have also proved that lutein and zexanthin are also important for eye health. And in some experiments, the two nutrients have showed very strong antioxidant power.
Like lutein and zexanthin, astaxnthin is also another very important nutrient for eye health. It is a very powerful antioxidant and can filter out UV rays.
The way that the three nutrients work can explain how to maintain eye health. Some bad habits or UV rays will cause some free radicals that will lead to oxidation reaction in the eyes.
This oxidation process will lead to great damage to molecule and the lens. Why will some senior citizens have to suffer from blurriness or blindness? This is because the free radicals in the bodies have increased greatly.
Fortunately, the three nutrients can be used to neutralize those free radicals before any damage occurred onto the eyes. Therefore, those nutrients are well known for combating free radicals and protecting eye health.
Those nutrients can be found in many leafy vegetables and other fruits. Generally, eating those foods every day can meet people’s daily demands. Furthermore, eating those foods can also benefit people’s bodies in many other respects.
