Here's What You Need to Know to Survive Flu Season
This year's flu season is still going strong.
As reported today by Dr. Tara Narula on CBS This Morning, the Centers for Disease Control and Prevention (CDC) has indicated:
3 Steps to Help You Beat the Flu
1) It's Not Too Late To Get A Flu Shot!
The CDC states, "...seasonal flu activity can begin as early as October and continue to occur as late as May. Flu activity most commonly peaks in the United States between December and March."
Last year "...influenza activity peaked in mid-March, 2016..."
"CDC recommends a yearly flu vaccine for everyone 6 months of age and older as the first and most important step in protecting against this serious disease."
2) Employ Good Health Habits To Help Stop Germs
1. Avoid close contact with people who are sick.
When you are sick, keep your distance from others to protect them from getting sick too.
2. Stay home when you are sick.
This will help prevent spreading your illness to others.
3. Cover your mouth and nose with a tissue when coughing or sneezing.
It may prevent those around you from getting sick.
4. Clean your hands.
Washing your hands often will help protect you from germs.
If soap and water are not available, use an alcohol-based hand rub.
5. Avoid touching your eyes, nose, or mouth.
Germs are often spread when a person touches something that is contaminated with germs and then touches his or her eyes, nose, or mouth.
6. Clean and disinfect frequently touched surfaces at home, work or school, especially when someone is ill.
Routinely use disposable disinfectant wipes to clean frequently touched objects and surfaces, including doorknobs, keyboards, and phones, to help remove germs.
7. Get plenty of sleep, be physically active, manage your stress, drink plenty of fluids, and eat nutritious food.
3) If You Do Get The Flu – Go See Your Doctor Promptly!
What Are the Symptoms for Influenza (also known as the Flu)?
People who have the flu often have some or all of these symptoms which usually come on suddenly:
Some people may have vomiting and diarrhea, though this is more common in children than adults.
* It's important to note that not everyone with flu will have a fever.
There are three FDA-approved influenza antiviral drugs recommended by the CDC this season to treat influenza:

Research Solutions for Peripheral Field Loss (PFL) of Vision
Prisms are a fascinating scientific invention with almost magical properties which most people find amazing.
Because an optical prism, made of transparent glass or plastic, refracts light rays resulting in dispersion of its component colors into that gorgeous "ROY G BIV" (Red-Orange-Yellow-Green-Blue-Indigo-Violet) spectrum which we call a rainbow.
However, as with most technological tools, there are many applications for prisms. In corrective lenses, a prism displaces images off axis, causing the image to be moved in such a way so as to allow it to be seen by those with certain vision impairments.
For example, prism lenses can correct some instances when a person has a misalignment of their two eyes relative to each other that results in binocular diplopia ("double vision"), also called "crossed eyes" or "cross-eyed."
In recent low-vision research news, it was reported that scientists designed new prism-based eyewear to help patients suffering from peripheral vision loss ("tunnel vision") avoid collisions with other pedestrians.
Some medical conditions which cause Peripheral Field Loss (PFL) of vision still retain good central visual acuity. On other words, they can still see what's in the center of their field of vision. Prism-based eyewear can serve as a "visual field expansion device" by creating artificial peripheral islands of vision at an angle making them visible to the unaffected central field of vision of the eye.
(Plain English Translation: Prism eyeglasses can redirect previously unseen peripheral images to the center of vision where they can be seen.)
In a number of cases, optic nerve damage from glaucoma may cause someone to lose their peripheral vision. However, because there are so many other diseases and accidents that can result in tunnel vision, a comprehensive eye exam by a qualified eye doctor is absolutely necessary.
Among the risks associated with peripheral vision loss are pedestrian collisions while walking. The new prism-based eyeglasses are meant to eliminate the risk of collision with other people in crowded locations such as malls, bus terminals or city streets. The study, "The risk of pedestrian collisions with peripheral visual field loss," was published in the Journal of Vision involving 42 retinitis pigmentosa patients with low vision.
Vision researchers set out to find out which direction these collisions usually occur, which led them to discover that collisions typically occur at a 45-degree angle. The study’s lead author, Eli Peli, OD, professor of ophthalmology with the Schepens Eye Research Institute, at the Massachusetts Eye and Ear, Harvard Medical School, said, "This means that any visual-field expanding device will be most effective if it can cover that angle."
Unfortunately, at present, commercial prisms are limited to 30-degrees. The research scientists made prototypes of high-power prism eyewear closer to the desired 45-degree mark to utilize the viewer's sighted area.
Patients who will require these glasses to expand peripheral vision, including those with retinitis pigmentosa (RP), Usher syndrome, choroideremia, advanced glaucoma, hemianopia, and similar diseases affecting eyesight, usually have good central vision.
The vision scientists, who conducted this study, used prism-based eyewear they developed, based on a mathematical model they created, that determined the risk of collision for those they studied. Experimentally, this new eyeglass design manipulated light to hit areas of the eye that still provide sight, thereby helping those experiencing peripheral visual field loss avoid collisions with other people while walking.
