There are two food supplements that are very important for the proper eye functioning and may help when talking about watching stereo 3D content without issues, these are Vitamin A and Litein. The lack of these two things in your daily diet can lead to reduced vision, light sensitivity and so on, however you should also be careful not to take too much additional Vitamin A, as there might be some side effects. So it is bet to consult with your doctor before starting to take additional food supplements in the form of Vitamin A and Lutein.

Vitamin A is needed by the retina of the eye in the form of a specific metabolite, the light-absorbing molecule retinal, that is absolutely necessary for both low-light and color vision. Deficiency of vitamin A, due to the unique function of retinal as a visual chromophore, can lead to the appearance of problems such as impaired vision, particularly in reduced light also called night blindness. Excessive vitamin A consumption can however lead to nausea, irritability, anorexia (reduced appetite), vomiting, blurry vision, headaches, hair loss, muscle and abdominal pain and weakness, drowsiness, and altered mental status.

Lutein as a food supplement is another thing that is important for proper eye function and additional protection. Lutein was found to be concentrated in the macula, a small area of the retina responsible for central vision. Studies suggest that intake of Lutein can decreases the risk for eye diseases such as Age-related Macular Degeneration as well as bring improvement in visual performance and decrease in glare sensitivity. While no recommended daily allowance currently exists for Lutein, positive effects have been seen at dietary intake levels of 6‚??10 mg/day. The only definitive side effect of excess Lutein consumption is bronzing of the skin.

But why are Vitamin A and Litein important for stereo 3D? The reason is simple, at least when talking about stereoscopic 3D content that you watch with glasses ‚?? active or passive, as these tend to block some light and reduce the light reaching each eye. Furthermore 3D hardware manufacturers do recommend that you use your 3D monitor or 3D HDTV is a darkened room with no additional light sources, so light sensitivity is even more important. In movie theaters when watching a 3D movie you are also wearing glasses that reduce the light reaching your eyes and the theater itself is kept pretty dark. You should also consider the possibility that the next time you watch something in 3D and you get nausea or a headache that you just may be taking too much vitamin A and the 3D is not causing this‚?¶ ;)

It is important to keep your eyes healthy and in good condition, so do have in mind the information above as a reference and something to think about at least, but do not do stupid things taking food supplements before consulting with a doctor! If you are having trouble perceiving stereoscopic 3D content, getting headaches or any other trouble it is a good idea to visit a specialist and do a check up of your eyes, it is quite often that the reason are issues with your own vision and not with the 3D content itself!
