Supplement for eyes

What kind of supplement do you remember when you hear it with the supplement for eyes? Various kinds of things are sold now even if I say a supplement said to be good for eyes. I am said to be it and think that there are very many people needing the supplement which is effective against eyes now that the symptom such as an eyestrain and asthenopia may be said to be disease now in the present age.
Eyes are tired, and, for the characteristic of the person whom asthenopia collects, do the people whom eyes are tired from other than the person working with a PC by the spread of working person and Internet using the PC not increase? After all a blueberry will be the first for the supplement of eyes.
The supplement which the ingredient of the blueberry is included in is sold as the supplement which is kind to eyes in various ways. Are there not many people who know because the blueberry supplement is sold to kind richness? When it is said why a blueberry is used as the supplement which is good for eyes, at first an ingredient called the anthocyanin is included in one of a blueberry. The anthocyanin takes the eyestrain, and eyes are known as an ingredient making it easy to show it.
In the blueberry supplement, beta-carotene is included elsewhere. Because beta-carotene works to make a necessary ingredient when I watch a thing with eyes called the rhodopsin when taken in in a body, I think that it may be said that it is an ingredient important at all for the eyes.
As for the people who lost eyesight, rhodopsin is not made, and, as for the person whom the symptom that eyes are hard to be seen at a dark place at night appears, the eyesight drop of eyes is thought about, but it is thought that rhodopsin decreases.
Therefore it is to be effective against the eyesight recovery of eyes, relieving fatigue of eyes very much to take in rhodopsin from a blueberry as a supplement. Because you must take in the anthocyanin included in the blueberry, beta-carotene to prevent rhodopsin from decreasing, as for eating a blueberry a lot raw, and taking it in, is what I take in with a supplement not first because it is difficult? It becomes the eyesight up of eyes by taking in a blueberry supplement, and increasing rhodopsin and thinks that it is to be important at all that the person whom eyes are tired from continues drinking a blueberry supplement because I am connected for the eyestrain prevention.
