If you’re a migraine sufferer, you know there are stark differences between headaches and migraines. (Location and severity of pain and accompanying symptoms are key differentiating markers, FYI.) But did you know that there are multiple types of migraines that can vary greatly based on symptoms, severity, and frequency?

“Migraines are generally divided into two overarching types: migraines with aura and migraines without aura,” says Nashville-based eye surgeon Ming Wang, M.D., Ph.D., of Wang Vision 3D Cataract & LASIK Center. Aura refers to a cluster of visual symptoms: seeing waves, stars, zig-zags, flashes of light, or even missing spots in your vision. On average, these symptoms can last anywhere from five to 60 minutes, explains Dr. Wang. “[Auras typically] appear suddenly, last for a short time, and then go away,” he adds. “They can occur with or without a headache. [Sufferers of] migraines without aura do not have any visual symptoms, only the headache.”

But one of the most alarming types of migraines might not actually “feel” like a migraine at all: When you get an ocular migraine, your eyes experience the effects more than anything else. (That’s not to say you won’t also have head pain, though. More on that below.) This can be a confusing and scary situation to be in, especially if you’ve never had an ocular migraine before. (Related: What I’ve Learned from Having Chronic Migraines)

Here, the lowdown on ocular migraines, so you can understand what you’re experiencing (and act accordingly).

What do diabetes, Graves’ eye disease, thyroid problems, cardiovascular disease, rheumatoid arthritis, multiple sclerosis, sickle cell anemia and several other medical conditions have in common?

They can all be detected during a careful eye examination.

Obviously, during an eye exam, your eyes are being checked for vision (farsightedness, nearsightedness, etc.), glaucoma, cataracts and macular degeneration. But other diseases that are located elsewhere in your body can be detected in your eyes, too. That’s because your eye is the only place where a doctor can have an unobstructed view of your blood vessels, nerves and connecting tissue, without any need for surgery.

The eye has the same microscopic tissue as your other major organs and is an important part of your larger nervous system. Abnormalities spotted in the eye may signal the same changes in other parts of your body.

A widely used drug for a bladder condition has possibly been damaging people’s eyes for decades without anyone’s knowledge.

Reports first surfaced last year that Elmiron, which is prescribed for interstitial cystitis, can be toxic to the retina.

This past weekend, researchers presented more evidence of Elmiron’s effects at the annual meeting of the American Academy of Ophthalmology in San Francisco. The study hasn’t been published yet in a peer-reviewed journal.

Ophthalmologist Dr Ming Wang, the director of Wang Vision 3D Cataract & LASIK Center in Nashville, Tennessee, describes the rover’s array of visionary cameras and sensors as ‘incredible’.

‘This allows it to collect panoramic data from many sources including ahead and below. In this way, the vision in some ways significantly surpasses that of human vision, which is limited to a fairly narrow field left and right and up and down,’ says Dr Wang, who holds a doctoral degree in laser physics.

The 2020 vision system performed well in the test, he notes, adding that its robotic vision is designed to gather ‘gross information for navigation’. The system focuses more on volume and data integration than exact resolution, because navigation does not require total exactitude.

Anyway, robotic vision is ‘an evolving field’, he says, adding that it is exciting to see how much progress has been made. In future, robot vision just might exceed human vision, he says. ‘Multiple cameras can provide more information on depth than humans can gather with our two fixed eyes. Laser displacement systems can use reflected light to more precisely measure distances than humans can with our naked eyes.’

The resulting phenomenal resolution may exceed what we naturally experience – an impressive 576 megapixels, according to Curiosity.com.

Even so, he says, while humans tie visual input to experience and read data ‘seamlessly’, a robot has limited ability to interpret and use it.

‘I feel that the chief challenge is not the acquisition of the data, but the interpretation of the data.’ Whereas gathering it is easy, it is hard to arm a robot with the programming needed to exploit the data and guide its interaction, he says.

He frames the outlook for the future of robot vision as ‘very interesting to see’. ‘There is such potential for incredible advances, as input sources can be almost limitless.’

Lori Steigerwald sees reading glasses from a unique perspective: She wears them and sells them.

Steigerwald has worn reading glasses for about 25 years. As national sales manager for retailer I Heart Eyewear and wholesaler Ron’s Optical in Livermore, California, she has sold hundreds upon hundreds of pairs of reading glasses.

As such, Steigerwald understands the importance of donning a pair of high-quality reading glasses if your up-close vision isn’t what it used to be.

Your trip home every day is a matter of life and death. You’re dodging other cars. You’re worrying about what to eat. You’re ducking your neighbor, the one with halitosis. When you finally shut your front door, a sense of calm prevails: You made it. You’re home.

But are you safe?

Shocking new research proves there are health dangers lurking in every house, with threats found in your dishwasher, shower, bedroom and more. In fact, there’s not a room untouched by scary substances that might make you sick. The Remedy asked the country’s top researchers for exactly what the issues are and how to solve each problem, so you can be happier, healthier, and safer–where it matters most.

Thinking that you’re healthy and actually being healthy are two very different things. You can go to the gym every week, floss after every meal, and go to sleep every night before 10 p.m., and still, you might be suffering in silence without even realizing it. But now is the time to learn about these less obvious health symptoms that could indicate a serious issue is going on–because when it comes to your health, knowledge is power.

#21: You have trouble driving at night

With cars flashing their brights at you and poorly lit roads, driving at night isn’t easy for anyone. However, if you find that driving after sunset is becoming increasingly difficult, this could be a sign of an eye issue.

“If a patient, generally age 50 and above, is bothered by symptoms such as difficulty in dim light, glare and halos, and trouble driving at night, they should consider seeing an eye doctor as this could indicate that they may need to have cataract surgery,” says Ming Wang, MD, PhD, of the Wang Vision Institute in Nashville, Tennessee. “Once performed, surgery can generally alleviate these symptoms.”

#22: You have pain behind your eyes

“One of the most commonly misunderstood symptoms of a sinus infection is eye pain,” says Wang. “This occurs because the sinuses sit in areas above, below, and next to the eyes. When pressure builds up in these areas, it can cause a dull pain that feels like it is coming from around or behind the eyes when it is actually coming from the sinuses.”

#23: Your vision suddenly changes

People of all ages and genders suffer from poor vision that requires correction. But while it’s unfortunately normal for our eyes to slowly deteriorate, you should be slightly more concerned if your vision changes suddenly out of the blue.

“Sudden vision changes could indicate a wide range of issues including macular degeneration, diabetic eye disease, vascular occlusions in the eye, retinal detachment, acute glaucoma, and more,” says Wang. “Patients should seek the care of an eye doctor immediately with any sudden vision change.”

Artificial tears are often the first line of defense for dry eye. Because they are so ubiquitous in eyecare, ophthalmologists and optometrists must regularly evaluate what’s new to the artificial tears market and what tear-use practices are most effective for patients.

Although some patients already use artificial tears, they may decide to visit their eye doctor because the drops don’t seem to be enough. They may think they need to try a different kind of tear or treatment. Some may realize the value of getting to the root cause of their dry eye.

Fifty is the new 40. And since 40 is the new 30, and 30 is the new 20, well–if you’re over 50, you’re basically 21, right?

In all seriousness, we’re glad age is just a number. Except for one thing: No one told your body.

After age 50, unexpected health problems can plague you, and prevent you from having the life you deserve. Unafraid to stare into the abyss, The Remedy asked the world’s top doctors about the most common ailments, and how you can get ahead of them. Read on, and save the surprises for your next birthday party.

“It can be easy with the busy routine of medicine to fall into poor eating habits,” says Dr. Wang. “After all, fast food and unhealthy options are much easier to come by. I feel it is important to make conscious decisions to eat healthier. The easiest way to do this is bring my own lunch to work when I can. Because food cooked at home can generally be prepared much more healthy than what is bought from a restaurant, it is a good way to control exactly what I am eating in the correct portion. It also has another benefit of avoiding the stress that can come from trying to grab a lunch if the lunch hour is busy.”

“Ballroom dancing has been a passion of mine since college at Harvard and MIT, when I was members of ballroom dancing clubs,” says Dr. Ming Wang, MD, PhD, an ophthalmologist in Nashville. “I still practice it today weekly and participate in local and regional championships. I find it to be a great way to relax, relieve stress, as well as stay active.” He also believes it’s helped him become a better doctor. “Through learning ballroom dancing, which requires connection and communications between two people as they move together synchronously, I have learned to feel what a patient feels, to listen to my patients, to communicate with them better, and the be more sensitive and aware of their suffering and needs.”

Jennifer Aniston is 50 years old. No wonder she’s doing ads for dry eye. “With age, the tear gland–called the lacrimal gland–has been shown to produce less tear volume,” says Dr. Ming Wang, an ophthalmologist. “Glands in the eyelids–called themeibomian glands–also start to atrophy and often produce less of the oily part of the tears that prevent their evaporation. Both of these factors contribute to nearly everyone over age 50 suffering from some form of dry eye. Dry eye produces symptoms including grittiness, watering, red eye, intermittent blurred vision, and discomfort.”

Recommendation: “Treatment includes over the counter tears. If these are not sufficient, a doctor can prescribe medications or treat with in office therapies,” says Dr. Wang.

It’s easy to go through the day without paying much attention to your eyeballs, or their overall health. But it’s also easy to add in a few habits here and there in an effort to take better care of your eyes. And maybe even prevent issues down the road.

That said, there are things you can do every day, as well, to protect your eyes and take better care of them. Read on for a few simple tips that can make a big difference, according to experts.

If you weren’t prescribed glasses as a kid, you might just think that you don’t need them and that you might never need them. This isn’t always the case.

Here are some signs you might need glasses.

NASHVILLE, Tenn.–A Middle Tennessee doctor is warning consumers about the hidden danger of laundry pods and detergents.

Viral online challenges have previously highlighted the dangers of ingesting laundry pods but Dr. Ming Wang of the Wang Vision Institute says laundry detergents can pose a risk to those using them for their intended purpose.

Pods, powder, and liquid laundry detergents are “basic agents” says Dr. Wang, meaning they have higher alkaline levels. “Detergents have to have a ph of seven to eleven because they’re meant to attach to clothing and pull from the clothing. Only higher alkalines do this and these can be the most damaging to the eye,” Dr. Wang says.

As thousands prepare to descend upon New York City’s streets to view the famous Manhattanhenge sunset, social media will likely be flooded with photos from residents and tourists who captured their best images of the celestial sunset, which happens four times annually.

Spectators who miss the two Manhattanhenge occurrences in May can wait until July to catch the year’s final showings of the unique event in which the sunset beams down the Manhattan street grid’s east- and westward roads in perfect alignment. That is, of course, if clouds don’t threaten to thwart views of the spectacular display, which has occasionally occurred in previous years.

Onlookers will want to capture the most stunning photos of the gorgeous sunset. Professional photographers shared their tips with AccuWeather for snapping great sunset images just in time for Manhattanhenge.

We reach for sunscreen because we know it’s necessary for protecting our skin from the sun’s harmful ultraviolet (UV) rays. But when we grab a pair of sunglasses, we may be thinking more about the way they look than about how important they are for protecting our eyes.

“Many patients underestimate how much UV rays can pose a significant risk to their vision,” says Samuel Pierce, an optometrist in private practice in Trussville, Ala., and president of the American Optometric Association (AOA).

In fact, a survey by the American Academy of Ophthalmology found that fewer than half (47 percent) of Americans check the UV ray protection level before buying sunglasses. Here’s how to get smarter about shades.

Whether or not people can actually predict the future is debatable. But according to science, you may not need any kind of psychic ability to predict what’s going to happen. The human body can do some things you may not even be aware of. As weird as it may sound, your body has the ability to predict certain things.

Before you get too excited, these predictions have nothing to do with how many children you’re going to have or how much money you’ll be making in 10 years. Instead, it can clue you in to potential health issues down the road and even how long you’re going to live.

“Optometrists are often the first to suspect and recommend testing for diabetes, based on clinical findings during [comprehensive] eye exams,” says Francisco Burgos, O.D., A.B.C.M.O., Katzen Eye Group, Lutherville, Md. This is important as more than 30.3 million people, or 9.4% of the U.S. population, had diabetes as of 2015, The American Diabetes Association reports. Furthermore, more than 84.1 million U.S. adults are pre-diabetic, and more than 90% of them don’t even know they have it, according to the CDC.

As such, optometrists should have in place practices to serve these patients to the best of their abilities, specifically, developing relationships with primary care providers, adding value via providing patient education, tracking clinical signs and, finally, coding appropriately.

A few months ago, I finally pulled the trigger and bought a Nintendo Switch. It’s the first gaming system I’ve owned since the Nintendo 64 growing up, and I told myself it’d be a good way to wean myself away from social media whenever I have downtime.

And then I remembered why I hadn’t bought a system since the Nintendo 64: I get awful motion sickness from first-person POV games. After 10 minutes of running around the Great Plateau in Breath of the Wild (the most recent installment of the Zelda series), I was running to my bathroom to blow chunks.

Despite the name, your eye isn’t actually moving at all. It’s that pesky eyelid. Eyelid twitching is pretty common and usually nothing to worry about, according to Dr. Ming Wang, PhD, Wang Vision 3D Cataract & LASIK Center. The condition of temporary or long-term eye twitching is called eyelid myokymia and it is the result of an involuntary misfiring of the neurons that stimulate your eyelid muscles.

Almost everyone will experience eye floaters in their lifetime, especially as they get older. They’re those tiny spots or lines that look like they’re in front of the eye, but they are actually floating inside it. Flashes, which look like streaks of lightning, are more common with age, too. Most of the time, neither floaters nor flashes are cause for worry. But under certain circumstances, they require immediate medical attention. Here’s what you need to know to protect your vision.

There are so many symptoms and problems that can stem from having dry eyes, including blurry vision, pain, redness, and even weird visual effects. It’s nobody’s definition of a good time. And yet so many folks deal with it on a regular basis.

“Studies show anywhere from 30 to 60 million Americans suffer from some form of dry eye, especially in the winter months,” Dr. Ming Wang, MD, PhD, of Wang Vision 3D Cataract & LASIK Center, tells Bustle. That’s a lot of people rubbing their eyes and blinking frantically in an effort to see.

Ready to get the best bang for your buck with your practice advertising in 2019? Then plan, be patient, and invest some time and money into the right message. The good news, for starters, is that eye practices traditionally are open to cutting-edge advertising and marketing ideas. “Ophthalmologists have historically been one of the most progressive groups regarding marketing,” said Chad Erickson, vice president of marketing and business development, Advice Media, Park City, Utah. This includes cutting-edge websites, YouTube channels with educational videos, and engaging social media, Mr. Erickson said. However, there’s always room for improvement.

Assistance for people with vision impairment has come a long way in recent years. Before tech transformed health care, the main option for vision assistance was magnifying lenses. Today’s tools include not only better magnification devices, but also apps and other products that use audio or tactile, rather than visual, feedback.

“These kinds of things put the zest and joy back in life for people who think they’ve had to give up some things,” says Neva Fairchild, an independent living specialist with the American Foundation for the Blind who is herself visually impaired. Fairchild was able to read a Valentine’s Day card from her daughter for the first time this year using an app called Seeing AI (more on that below).

Your eyeballs can have quite a few health problems, all on their own. So it’s important to monitor your vision for changes, and see an eye doctor if anything feels out of the ordinary. But depending on your eye color, you might also be prone to certain health issues, both related and unrelated to the actual eye itself.

Imagine this: a warm Saturday afternoon with no more chores to check off of your to-do list. You have no plans, no responsibilities, nothing to worry about except enjoying the time to yourself. If you’re anything like me, this kind of day can nudge you into an impromptu, refreshing nap in no time at all. But, for some people, drifting off isn’t as simple as just closing your eyes. If you aren’t lucky enough to have 20/20 vision (same, friend), you’ve probably wondered whether it’s OK to nap with your contacts in. Not to scare you too much, but according to experts, taking your contact lenses out of your eyes is one pre-nap ritual you should definitely be sure to make time for.

It’s totally common to be itchy from time to time. However, if the feeling sticks around, sometimes that itchiness can be a symptom a larger health issue. In other words, even something as small as a tick bite can turn into a serious infection, causing larger health problems down the line. For that reason, it’s important to check in with your body and recognize when itching might actually need extra medical attention.

Dozing off with our contact lenses in is all too easy sometimes, especially after a long day. But sleeping with your contacts in is actually super dangerous. According to LiveScience, about one-third of contact lens users report napping or sleeping with contacts in, but according to research, sleeping with your contacts lenses in can lead to some scary eye injuries. In a study published by the National Institutes of Health (NIH), researchers think they may have pinpointed why sleeping with contacts in is so dang risky. Apparently, the risk of corneal infections is scary high when it comes to sleeping with contacts in, and the risk is even higher if contacts are kept in overnight. When you watch the news, it sometimes feels like the US is unraveling. But while we definitely have some problems that need fixing, there is still a ton that we can be optimistic about in the US.

Sometimes it takes someone with an outside perspective to give us a bit of an objective reality check.

The most famous example of this was Alexis de Tocqueville. Tocqueville was a French diplomat, a foreigner, who helped Americans appreciate how lucky they really were.

Similarly, I reached out to more than 30 successful immigrants, people who came to the US with almost nothing and built very successful careers and asked them to share why we can be optimistic about the US’s future today.

I hope you find these ideas meaningful.

There are few things as unpleasant as sustaining some insult or injury to our precious eyes. Whether it’s an eye gnat, soap, or even some dust, no one wants anything in their eyes that shouldn’t be there. And if it’s something that happens to not want to come out, no matter how many eye drops you rinse with? That’s the worst of the worst. So it really helps to know the doctor-approved thing to do if something’s really stuck in your eye — and the one thing a doctor says never to do.

Myopia affects almost 30 percent of the population in the United States. Severe myopia is associated with complications that can threaten your eyesight.

However, there’s some promising news on the horizon, at least for children.

Glasses that proponents say are specially designed to slow the progression of myopia in children are scheduled to launch this summer.

The lenses, developed by scientists at the Hong Kong Polytechnic University, were found to reduce the progression of myopia for 60 percent of the young participants in a two-year, double-blind, randomized clinical trial.

In addition, the new lenses completely stopped further vision loss in 21 percent of trial participants.
