What Causes Halos Around Lights?

Low Vision Doctors of Ohio Local Cataract, Astigmatism, Fuch’s Dystrophy and Glaucoma Eye exams and treatment near you in Columbus, Ohio

Have you ever seen bright rings or “halos” around sources of light? Read on to learn what can cause halos and when they’re a reason to visit an eye doctor near you.

For local Management of Ocular Diseases near you in Columbus, Ohio

Seeing bright rings or “halos” around sources of light can either be normal or a cause for concern. Below, we’ll explain the most common reasons that people see halos and when you should visit your eye doctor.

We see halos around light fixtures and headlights when light entering the eye from a bright object is bent in an unusual way. This causes the bright light to appear as if it is surrounded by a ring of light, known as a halo. Several conditions can cause light to bend in this way.

  • CataractsA cataract is a clouding of the eye’s natural lens. Cataracts usually develop slowly and are most often seen in older people.

    When the lens becomes cloudy, light is dispersed abnormally as it enters the eye and causes a person to see halos around lights. In fact, seeing halos around lights is one of the most common symptoms of cataracts. Other symptoms that may accompany cataracts are blurred vision, light sensitivity, and difficulty seeing at night.

  • AstigmatismThis eye condition occurs when the cornea (the front surface of the eye) is irregularly curved. People with astigmatism may see halos around lights because of the way the cornea refracts incoming light.
  • Fuch’s Dystrophy This progressive genetic disease causes the cornea to swell. As the cornea swells and becomes misshapen, it causes light to enter at an incorrect angle. As a result, people with this condition see halos around lights.
  • GlaucomaGlaucoma occurs when the optic nerve becomes damaged due to high inner eye pressure, and is a leading cause of blindness worldwide. Seeing halos around lights can be an early sign of acute glaucoma, which is considered a medical emergency.

    If you suddenly start seeing halos around lights in addition to other symptoms like headache, vomiting, blurred vision, eye pain, and weakness, seek medical care without delay.

  • Dry Eye SyndromeDry eye syndrome occurs when the eyes are chronically dry. In moderate to severe cases, the eye’s surface can become irregularly shaped, which can cause light to enter at an odd angle.

When To Visit Your Eye Doctor

If you see halos around lights, it’s best to schedule a timely eye exam at an eye clinic near you, even if you suspect you know why it’s happening.

A comprehensive eye exam by a qualified eye care professional is the only way to rule out a serious problem.

Many eye diseases can be quickly and easily diagnosed during a Comprehensive eye exam, Pediatric eye exam and Contact lens eye exam. If you were diagnosed with an eye disease, such as Cataracts, Pink Eye or conjunctivitis Myopia or Nearsightedness , Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Is LASIK eye and vision surgery an option for you ? Our Columbus eye doctor is always ready to answer your questions about eye disease and Contact lenses.

  • What is a cataract? How will I know when I have one? What can be done to fix it?

    A cataract is a clouding of the crystalline lens. The crystalline lens sits behind the iris or the colored part of the eye. Its function is to fine-tune our focusing system by changing shape as we view objects at different distances. Our lens eventually loses its ability to change shape; this is when we require reading glasses or bifocals. In addition, the crystalline lens can become cloudy or yellow as a part of normal aging. This is also known as an age-related cataract. Normal, age-related cataracts are unavoidable and everyone will develop them at some point if they live long enough. The discoloration of the lens leads to an overall blur, a decrease in contrast sensitivity, and a worsening of glare, especially at nighttime. Because they tend to develop gradually, the symptoms are often unnoticed by the patient. A yearly eye exam will allow your optometrist the opportunity to identify cataracts and advise on how to proceed. When your optometrist decides your cataracts are affecting your vision and are advanced enough to remove, you will meet with an ophthalmologist. Cataract surgery is a safe and effective outpatient procedure that will reverse any vision loss caused by cataracts, and it is usually covered by your medical insurance.

  • My previous eye doctor told me I have “stigma!” Am I going to go blind?

    Stigma is actually referring to a type of refractive error known properly as astigmatism, and no, you will not go blind from having astigmatism; it is not a disease, in fact, it is relatively common. There are three types of refractive error, myopia, hyperopia, and astigmatism. The former two are more regularly referred to as nearsighted (cannot see far away) and farsighted (cannot see up close). Astigmatism is simply the third category; it affects both the near and far vision at the same time. Much like nearsightedness or farsightedness, astigmatism is corrected using glasses or contacts. Technically speaking an eye with astigmatism requires two different prescriptions to correct vision in one eye due to the more oval shape of the cornea. This will require a more specialized contact lens and a more in-depth fitting procedure. Nonetheless, your eye care provider can, and will, correct your astigmatism with glasses and/or contacts.

  • What exactly is glaucoma?

    Glaucoma is a condition in which the eye’s intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it’s not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.

Does Obesity Impact Eye Health?

Nation-wide awareness about the vast dangers of obesity is at an all-time high, with TV shows like “The Biggest Loser” and health initiatives such as Michelle Obama’s “Let’s Move!” campaign shining a spotlight on the importance of fitness and good nutrition. However, despite the public’s knowledge of obesity’s effects on hypertension, stroke, and diabetes, many are not aware of how it damages eye health and vision.

Increasing evidence shows that people who are clinically obese have an elevated risk of developing serious eye diseases. It is widely known that expanding waistlines place people at a higher risk of getting diabetes, heart disease, and cancer — but researchers say the link between obesity and deteriorating vision is the “risk factor that no one talks about”. Professor Michael Belkin and Dr. Zohar Habot-Wilner, from the Goldschleger Eye Institute at the Sheba Medical Center, found a consistently strong correlation between obesity and the development of four major eye diseases that may cause blindness: 

  • Age-related macular degeneration (AMD)
  • Cataracts
  • Glaucoma
  • Diabetic retinopathy

The researchers said that although the evidence was out there suggesting a link between obesity and these conditions, their study emphasizes the optometric risks of obesity which can help motivate people to shed those extra pounds.

How Obesity Contributes to Eye Disease

A Body Mass Index (BMI) of 25 is considered overweight and above 30 is regarded as obese. A high BMI is tied to several chronic systemic health conditions such as diabetes, cardiovascular disease, and stroke, among others. Recent research indicates that a handful of ocular diseases can now be added to that list. 

Serious eye conditions such as diabetic retinopathy, glaucoma, and age-related macular degeneration are more common in individuals with obesity, as well as floppy eyelid syndrome, retinal vein occlusions, thyroid-related eye diseases, and stroke-related vision loss. 

The connection between obesity and these eye diseases is likely due to the increased risk of peripheral artery disease. This occurs when the tiny blood vessels bringing oxygen to parts of your body like the feet, kidneys, and eyes become compromised.

Your eyes are particularly prone to damage from obesity because the blood vessels in the eyes (called arterioles) are easily blocked, since they’re extremely thin and small — as thin as ½ the width of a human hair! 

Most people are not aware that obesity may increase the rate of developing cataracts, too. Cataracts result when the focusing lens in the eye becomes cloudy and requires surgery to be replaced. In addition to age, cataract development is associated with obesity, poor nutrition, gout, diabetes and high blood sugar levels, though the exact cause isn’t clear.

A Healthy Lifestyle Can Reduce Your Risk of Ocular Disease

Knowing about the risk of vision loss may give those with a high BMI the extra motivational boost they need to lose weight. The good news is that a few lifestyle changes can reduce the associated risks.

An active lifestyle and a balanced, nutritious diet lower obesity and improve overall physical and eye health. Give your body a boost by incorporating important nutrients, such as vitamins C and E, zeaxanthin, omega 3, zinc, and lutein, many of which are found in green leafy and dark orange vegetables, as they have been shown to reduce the onset, progression, and severity of certain eye diseases. 

We Can Help Keep Your Eyes Healthy in Columbus

While a healthy diet and regular exercise greatly increase your chances of living a disease-free long life, they alone are not enough to ensure long term healthy eyesight. Regular eye exams with Dr. Rinkov can help prevent or detect the onset of ocular disease, and maintain vision that is clear and comfortable.

If you have any questions or concerns regarding your vision or eye health, don’t hesitate to call Low Vision Doctors of Ohio — we’re here for you. 

3 Ways Diabetes Can Affect Your Vision and Eyes

Did you know that people with diabetes are 20 times more likely to get eye diseases than those without it? There are three major eye conditions that diabetics are at risk for developing: cataracts, glaucoma, and diabetic retinopathy. To prevent these sight-threatening diseases, it’s important to control your blood sugar level and have your eyes checked at least once a year by an eye doctor. 

But First, What Is Diabetes?

Diabetes is a disease that is associated with high blood glucose levels. Insulin, a hormone produced by the pancreas, helps our cells get energy from the sugars we eat. Diabetes develops when the body doesn’t produce or respond to insulin effectively, leaving too much sugar in the blood stream instead. Over time, diabetes can lead to potentially irreversible ocular damage and poor eyesight. However, by taking care of your blood sugar levels and your eyes, you can prevent vision loss.

Annual eye exams are recommended for everyone, but routine screenings are even more important for diabetics. Eye doctors may send diabetic eye health reports to a patient’s primary care physician or internist to adjust medication as needed to prevent complications.

What’s the Link Between Vision and Diabetes? 

Blurred vision or fluctuating eyesight clarity is often one of the first noticeable signs that diabetes has begun to affect your eyes. Sometimes, fluid leaking into the eye causes the lens to swell and change shape. This, in turn, makes it difficult for the eyes to focus, resulting in fuzzy vision. Such symptoms can indicate that an eye disease is developing, or may simply be due to imbalanced blood sugar levels which can be rectified by getting your blood sugar back to healthy levels. 

If you start to notice blurry vision, make an appointment with Dr. Rinkov as soon as possible.

The 3 Ways Diabetes Impacts Vision 

Cataracts

While cataracts are extremely common and a part of the natural aging process, those with diabetes tend to develop cataracts earlier in life. Characterized by a clouding or fogging of the lens within the eye, cataracts impede light from entering the eye, causing blurred vision and glares. The best treatment is cataract surgery, which is very safe and effective. 

Glaucoma

Glaucoma refers to a group of eye diseases characterized by optic nerve damage. Since it tends to impact peripheral vision first, glaucoma often goes unnoticed until significant damage has occurred. However, routine glaucoma screenings can detect warning signs; early treatment can prevent disease progression and vision loss. 

Although there is no true cure for glaucoma, most glaucoma patients successfully manage it with special eye drops, medication, and on occasion, laser treatment or other surgery. The earlier glaucoma is diagnosed and managed, the better the outcome.

Diabetic Retinopathy

Diabetic retinopathy occurs when the small blood vessels on your retina (capillaries) become weakened and then balloon (microaneurysm) due to poorly controlled blood sugar levels. The resulting poor blood circulation in the back of the eye causes more abnormal blood vessels to grow, which also bleed or leak fluid, and can lead to scar tissue, retinal detachment and even blindness, over time.

Often there are no symptoms until the advanced stages of diabetic retinopathy, where patients may begin to see spots and missing patches in their vision. Retinopathy can be treated through surgery and eye injections, but the best way to prevent this disease from progressing is to regularly have your eyes screened.

The good news is that diabetic eye disease can often be prevented with early detection, proper management of your diabetes and regular diabetic eye exams. Contact Low Vision Doctors of Ohio in Columbus to set up your eye doctor’s appointment today. 

How Smoking Impacts Vision

Smoking harms nearly every system in your body — including your eyes. 

Though we are all aware of the health effects associated with smoking, such as lung cancer, heart disease, and bad teeth, few know about the negative impact it can have on our vision. 

Smoking and Eye Disease 

Smoking, especially 20 cigarettes or more daily over a long period of time, can adversely impact your vision. Cigarette smoke is made up of compounds that can damage health and have been shown to cause cerebral lesions which affect the area of the brain that processes vision.

More specifically, tobacco addiction increases the risk of developing vision-robbing diseases such as macular degeneration (AMD), cataracts, glaucoma, diabetic retinopathy. Moreover, smoke is an irritant that can cause or exacerbate dry eye syndrome. Below we’ll delve a little further into each of these conditions. 

Age-Related Macular Degeneration 

Smokers run a high risk of developing AMD, a condition that severely impairs central vision, making it difficult or impossible to read, drive, recognize faces and colors, and leads to permanent vision loss in those aged 65 or older. Fortunately, the risk can be dramatically diminished by putting an end to tobacco smoking — even if later in life. 

Cataracts

Heavy smokers double their risk of developing cataracts, the leading cause of blindness. Cataracts are characterized by clouded, blurred or double vision, photophobia, and reduced night vision. However, cataract surgery is common and replaces the clouded lens with an artificial intraocular lens. 

Uveitis

Uveitis, the inflammation of the eye’s central layer, is an ocular disease that can lead to blindness. This condition damages important structures of the eye, notably the iris and retina, and can lead to cataracts, glaucoma and retinal detachment. Smokers have a 2.2 times higher risk of developing uveitis than non-smokers. 

Diabetic Retinopathy

Smoking raises one’s risk of developing diabetes by up to 40 percent thereby increasing the risk of retinopathy as well. Diabetes damages the blood vessels in the retina, causing them to leak blood into the eye, which — in severe cases — can deprive the retina of oxygen and result in blindness.

Dry Eyes

Dry eye syndrome is a common eye condition characterized by insufficient tears to keep your eye lubricated, or the tears are not composed of the correct balance of water, lipids, and mucous to maintain proper lubrication. Common symptoms include red, itchy, and gritty eyes.

Heavy smokers, and those exposed to secondhand smoke, not only double their risk of developing dry eye but also exacerbate an existing condition, especially among the contact lens wearers.

Secondhand Smoke and Eye Disease 

Secondhand smoke— which includes the smoke that emanates from the end of a cigarette as well as the smoke exhaled— is nearly as harmful to health and vision. Second-hand smoke places others’ eyesight in danger, particularly in young children and infants. Furthermore, studies indicate that women who smoke during pregnancy put the newborn baby at risk of being born with eye disease or visual impairment that could affect his or her ability to learn.

Stop Smoking to Save Your Vision

The good news is that giving up smoking can have an immediate effect on your health — and it’s never too late to quit! Once the habit is broken, your body will begin to repair itself to prevent vision loss. It can be challenging to quit, as it requires dedication, support, and advanced planning. Dr. Rinkov and the rest of the staff at Low Vision Doctors of Ohio in Columbus care about your health and will be happy to provide any assistance or resources to help you quit smoking and improve your eye health. Keep in mind that if you smoke, quitting smoking is the most important step you can take to protect your health and vision.

Cataract Awareness Month

June is Cataract Awareness Month. During this important time, people living with cataracts (and their loved ones) are encouraged to talk about their personal experiences by giving each other helpful information and sharing their knowledge and advice. Use the hashtag #CataractAwarenessMonth on your social media channels to encourage and support others.

Did you know that over 24 million Americans have cataracts? More than 3.5 million Canadians are blind from cataracts, making it one of the most common – and serious – eye conditions today. Dr. Rinkov treats cataract patients from all over Columbus, Ohio with the newest and most effective methods of eye care.

With millions of people living with the condition, it’s now more important than ever to bring awareness to this serious condition.

What Are Cataracts?

So what exactly are cataracts?

The lens of the eye is normally clear, which allows you to see things clearly and in sharp detail. Over time, the lens can become cloudy, causing blurry vision. It’s as if you’re looking through a dirty window and can’t really see what’s outside. This clouding of the lens is called a cataract, and it can affect one or both of your eyes.

What Causes Cataracts?

Aging is the most common cause of cataracts. The lens of your eye contains water and proteins. As you age, these proteins can clump together, and when that happens, the normally clear lens becomes cloudy.

Did you know that certain types of major eye surgeries and infections can trigger cataracts? Other issues that can lead to cataracts include congenital birth defects, eye injury, diseases, and even various kinds of medications. If you’re already developing cataracts, be careful when going outside. UV rays from the sun can make cataracts develop faster.

How Can I Lower My Risk of Cataracts?

Certain risk factors increase your chance of developing cataracts. These typically include:

  • Diabetes
  • Excessive alcohol consumption
  • Family and medical history
  • Medications
  • Obesity
  • Smoking
  • UV ray exposure

To lower your risk, consider reducing your alcohol intake, quit smoking, start an exercise program, eat foods rich in vitamin A and C, and wear 100% UV blocking sunglasses.

Common Symptoms of Cataracts

If you have cataracts, you may experience some common symptoms like:

  • Blurry vision
  • Colors that used to be bright now appear dim
  • Double vision
  • Glare from natural sunlight or from artificial light, like light bulbs and lamps
  • Halos around lights
  • Night vision problems
  • Sensitivity to light

If you or a family member notice any of these signs, talk to Dr. Rinkov right away. The sooner you seek treatment, the faster we can help you get back to clear vision.

Coping With Cataracts

If you’re experiencing vision problems from cataracts, there is hope. If you have a mild case, a combination of a different eyeglass prescription and better lighting in your home, office, or other environment can improve your vision. In more advanced cases, your optometrist will likely recommend cataract surgery to remove the cloudy lens and replace it with a clear one.

Do I Need Cataract Surgery?

Cataract surgery is one of the most common procedures today. In fact, the American Academy of Ophthalmology estimates that 2 million people undergo the procedure each year.

During the procedure, the doctor will gently remove the cataract from the eye and replace it with an artificial intraocular lens (known as an IOL). Because it’s a common procedure, cataract surgery is usually performed in an outpatient clinic or in your eye doctor’s office. There is no need to stay in a hospital and you can usually resume your normal activities in just a few days.

If you’ve exhausted every other solution and still suffer from blurry vision from cataracts, surgery may be an option. Schedule a consultation online or call 614-401-3750 to book an eye doctor’s appointment at Low Vision Doctors of Ohio and together, we’ll determine if cataract surgery is right for you. 

During this Cataract Awareness Month, share your stories and successes, and give your loved ones hope for a healthy and high quality of life.
