Color blindness is a condition that's often misunderstood by a lot of people in the world. Contrary to popular belief, a person who is colorblind can still see colors; they just don't see them in the same strength or frequency that a normal person sees them. The name itself is actually pretty misleading; the official name for color blindness is color vision deficiency, which puts a finer point on the condition that these people are dealing with. If a person is extremely color blind, that is, on the lower end of color receptiveness, they will usually only be able to distinguish about 20 distinct hues in their visual field. This is less than one fifth of what a normal person will be able to see, since most people can actively tell the difference between over 100 individual hues. Color Blindness also affects men much more often than it affects women, mostly because the Color Blindness Genetics that determines this or the ability to distinguish colors, as a whole is located i

Several new vision inventions are coming out of Israel. An innovative retinal diagnostic test can be completed entirely online. Also, an implantable miniature telescope restores vision to those with partial retinal damage. This technology is available in the United States today or within the next year. At-Home Retinal Diagnostic Test AEYE Health is a privately-held online health company headquartered in Tel Aviv and New York that provides online retinal diagnosis. Formed in 2016, AEYE’s team of seasoned entrepreneurs invented an AI system with a database of 100,000 images of the retina and its inner structures, the basis of their diagnostic tool. According to their website, all it takes is two easy steps to obtain results. Their aim is to become by 2020 the first FDA-approved retinal screening solution for home use. Retinal imaging, a simple procedure, can detect a variety of medical conditions that prevent blindness and can save lives, i.e., diabetes/prediabetes, diabetic retinopat

Lack of Vitamin D has been associated with eye diseases like uveitis, macular degeneration, and dry eye. Vitamin D deficiency is also linked to cancer, immune disorders, heart disease, high blood pressure, osteoporosis, bone pain, depression, asthma, multiple sclerosis, and even dementia. Shockingly, more than 40% of the US population is Vitamin D deficient. The body manufactures Vitamin D, so why is deficiency wide spread? Indoor living, aging, and many other factors are behind this virtual pandemic. How can you measure your vitamin D levels? How can you get enough? Isn’t fortified milk enough? Should you take a supplement? Which one? What is Vitamin D? Vitamin D is an antioxidant that fights free radical damage in the body and reduces inflammation.

Smartphones, computers, tablets, and televisions are being blamed for a sharp increase in teenagers’ need for eyeglasses in the United Kingdom. The number of teens who need glasses nearly doubled, from 20% in 2012 to 35% in just four years later. 1 Myopia was the diagnosis for 66% of these teens. Myopia, or nearsightedness, makes distant objects look blurry. Excessive up-close focusing is a risk factor for developing myopia. Myopia Refraction Error Nearsightedness generally develops in childhood and stabilizes in teenagers. The eyeball becomes too long. Similar to a projector, light from the eye focuses on the retina. With nearsightedness, the light focuses in front of the retina, not on it. Sometimes the cornea is misshapen. Tiny muscles in the eye are supposed to refine focus. The cornea is fixed, but the lens is flexible and should compensate to provide sharp vision. However, researchers have found a strong association between close-up focusing and myopia. For example, in some
