THE TRUTH ABOUT COMMON EYE MYTHS

Are you curious about what really will or won't affect your sight, and if you can do anything to improve it?
Not only do we dispel some myths you may have heard, but we also have the best solution to help you maintain healthy eyes and to even improve your focus and vision. And, since sight is often the sense we rely on the most, that’s really great news!
Vision Pro offers Lutein and other vital nutrients specifically for the health of your eyes – even if you have macular degeneration, cataracts, and blurred focus. And since it’s in an oral spray, you know you’re getting the maximum absorption and benefit of all its powerful ingredients!
#1: Carrots are good for your vision.
False: "Carrots are not the magic food for your eyes," says Ophthalmologist John Hagan, III, MD, FACS. "If I had to pick one magic food, eat spinach." While carrots are rich in beta-carotene, a precursor to vitamin A, most people are not deficient in beta-carotene; it's a nutrient that many foods (fortified, or not) have. "I'd rather people get more lutein," says Dr. Hagan. Lutein, a nutrient abundant in spinach, is a chemical substance that is important to macular health. Most Americans are Lutein-deficient. The human body cannot make Lutein (it also gets harder to absorb it as you age), so sufficient levels depend on diet. Other dark-colored veggies like asparagus and broccoli are also great natural source of Lutein, as are cooked tomatoes and cooked tomato products like pasta sauce. You can also purchase multivitamins containing Lutein, but many don't contain the recommended daily amount (6 mg), so be wary. Vision Pro contains 10 mg of this important nutrient, plus much more!
#2: Working in front of a computer or watching TV too often will damage your eyes.
False: The only thing that happens is our eyes get strained and tired. Viewing a television or computer monitor reduces the amount of times a person blinks, leaving the eyes dry and more prone to irritation and fatigue. "The number one thing that aggravates eyes is having dry eyes," says ophthalmologist Michael Kutryb, MD. Of the two, he says, "Staring at and focusing on a computer monitor is actually far more taxing on the eyes than watching TV."
#3: Wearing contact lenses too long can make you go blind.
True: Wearing contact lenses for too long can cause protein to build up on the surface of the eyeball, which can block oxygen circulation to the eye. Corneal ulcers, bacterial or fungal infections, and irritation caused by oxygen deprivation are common problems that can result from leaving contacts in for too long. These can all lead to complications that can cause blindness.
#4: Wearing glasses will slowly weaken your vision.
False: Glasses don't weaken your vision over time. The eyes naturally change throughout one's lifespan, and glasses have no effect on that process.
#5: Wearing sunglasses will protect your vision.
True: But only if the sunglasses have the proper protection. "People don't realize how damaging UV radiation can be," says Dr. Kutryb. Overexposure to UV rays damages the lens of the eye and may play a role in developing cataracts. Too much UV exposure can also damage the eye's retina, the light-sensitive lining at the back of the eye. UV rays can also reflect off surfaces to cause damage to the cornea. Sunglasses provide crucial protection and should be polarized and protect against both UV-A and UV-B rays. Wearing shades that are merely tinted harm you more than they help you. The tint causes pupils to get larger, allowing more unfiltered UV rays to get into the eyes.
#6: Certain types of light are better for your eyes than others.
False: Some claim that working under fluorescent lighting gives them eyestrain and headaches. Others claim that natural lighting is poor for reading. But it's very unlikely that people will have a real positive or negative physiological reaction to light, according to Dr. Hagan.
#7: Anyone can benefit from Lasik eye surgery.
False: Lasik eye surgery, a type of vision correction procedure that uses specialized lasers to change the shape of the cornea, is only capable of correcting deficits in vision that are correctable with glasses. "If somebody has reduced vision due to macular degeneration (damage to the center of the pupil, an area critical for directing where the eyes should focus), detached retina, glaucoma or because of some other eye disease, Lasik won't do a thing," says Ophthalmologist John Hagan, III, MD, FACS.
#8: 20/20 score is the best possible score you can get.
False: "Visual acuity is distributed like a typical bell shaped curve," says Dr. Hagan. "20/20 is at the top of the curve. But there are people on both sides of that." It is not unusual for people to have vision better than 20/20. Some are blessed with 20/15 and 20/10."
#9: Having a night-light on for infants or toddlers will make them near-sighted.
False: In the May 13, 1999 issue of the medical journal, Nature, University of Pennsylvania researchers raised concerns that the use of a night-light in the rooms of infants will make them five times more likely to develop myopia (near-sightedness) than infants left in a dark room. However, this notion has since been debunked, thanks to a study in the May 2001 edition of Investigative Opthalmology and Visual Science. Scientists at Yerkes National Primate Research Center at Emory University and the College of Optometry at the University of Houston assert that constant light does not cause near-sightedness in infants. There are many factors involved with vision development that children inherit and some that are involved with how their eyes acclimate to their surroundings during the critical years of development. However, night-lights don't contribute to any vision problems, including near-sightedness.
