VISION THROUGH ANIMAL EYES REVEALS SURPRISING COLOR
We condition the eye as a muscle and Keith does a lot of innovative and cutting-edge stuff. Trying to buy time Smithsons foremost mission is to test players eyes and provide corrective lenses. A pitcher, he said, can do fine with 20/20 vision, but he is more likely to push a position player with the same eyesight to use contact lenses, which can improve the acuity to 20/15. (He doesnt perform corrective laser surgery, but provides referrals for the procedure.) He also provides the colored contact lenses to help with the sun and different hitting backgrounds, like the amber-colored ones Harper wore during last seasons playoffs . But after the basic eye testing, Smithson wants to help the Nationals make quicker decisions and improve their reaction speed. There are seven muscles around the eye, and Smithson teaches players to fine-tune them.

Blurred vision? Eye doctor myths exposed – learn how to exercise your eye muscles for restoring healthy vision and eliminating prescription glasses
What they need is eye exercise. But don’t expect the for-profit vision industry to tell you about any of that. Like Big Pharma, they only make money when people stay uninformed, believing they cannot help themselves. Here at NaturalNews, we specialize in teaching people how to restore health by taking responsibility for their own health outcomes, thereby avoiding the outrageous costs (and inhumane suffering) caused by the medical industry in all its forms.

If you spend two or more continuous hours in front of a digital media screen each day, you are most at risk for CVS. Why? Because digital media screens are often held close to the eyes, causing eye strain as your eyes shift in and out of focus to view pixilated images on the screens. Plus, some people don’t blink their eyes enough when using iPads or other tablets, which can make eyes dry and irritated. To reduce the risk, users should take a short break every 20 to 30 minutes and try to look away at a distant object for a few seconds. Also, avoid prolonged work on a tablet. Instead switch to a computer screen that is about 20-28 inches/50-71 cm away from your eyes, according to the American Optometric Association.

iPads and tablets may cause eye problems or ‘computer vision syndrome’
Like the color-discriminating apparatus of the human eye, that of insects depends on recording and comparing light intensities in three regions of the electromagnetic spectrum. Few Are Totally Colorblind Humans are rarely, if ever, totally colorblind, but close to 8 percent of Causasian males lack functioning sensors in one of the three categories needed for full color vision. The human retina contains two basic kinds of receptors: the cones, which provide the basis for color vision, and rods, which record very faint light. Each cone contains a photopigment particularly sensitive to one of three parts of the light in the electromagnetic spectrum.
