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 North York, Ontario

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 North York 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.

Who is the Ideal LASIK Candidate?

York Mills Eye Care LASIK Guidelines from your North York, Ontario Eye Doctor. near you in North York, Ontario

What criteria determine if you are eligible for LASIK?

  • Good eye health, with no ocular disease. Conditions such as chronic eye infections, severe dry eye syndrome, cataracts, corneal disorders, macular degeneration, uncontrolled glaucoma, and eye injuries may make LASIK a poor choice for you.
  • Corneal thickness must be adequate for reshaping your cornea. Performing LASIK on a cornea that is too thin or extremely irregular can reduce the success of the procedure. However, this rule isn’t as steadfast as it once was, because new types of LASIK are now available that enable surgeons to perform the laser vision correction. Our North York, Ontario, will measure your cornea during your LASIK consultation eye exam to recommend the most suitable method of laser eye surgery.
  • The best visual success with LASIK is with people who have prescriptions in the following parameters: up to +6 diopters for farsightedness, up to 6 diopters of astigmatism (cylinder), and up to -12 diopters of nearsightedness.
  • Ocular maturity is important. The best LASIK results are achieved in people who have had a stable vision prescription for about a year before undergoing refractive surgery.
  • A good overall health condition, with no pre-existing conditions that can slow healing, such as hypertension, Sjogren’s syndrome, and poorly controlled diabetes.
  • LASIK is FDA-approved for patients above age 18. Generally, there is no maximum age for laser eye surgery. But, be aware that once you are in your 40s, you may still require reading glasses to correct near vision after undergoing LASIK.
  • LASIK is not suitable for women who are pregnant or nursing, due to the fact that hormonal changes can affect the corneal shape. Typically, it’s advised to wait a few months after pregnancy.

Set realistic visual expectations

If you are seriously considering LASIK, it’s important to face reality. While most people are thrilled with their LASIK results, there are still risks and possible side effects and complications. You need an experienced eye doctor to perform a personalized eye exam and consider whether or not you are an ideal candidate for laser eye surgery – as well as advise you about which specific type of vision correction is most appropriate.

Take a break from digital devices to allow our eyes to rest and prevent eye strain near you in North York, Ontario

The more time we spend on digital devices for work, school, and entertainment, the greater the risk of developing eye strain. Staring at a screen for an extended period of time tires out our eye muscles and can also cause dry eye, headaches, blurred or double vision, sensitivity to light, and soreness in the neck and shoulders.

Fortunately, there are exercises to relax and refresh your eyes and prevent eye strain discomfort.

Eye Exercises

Since the use of digital screens has become a large part of our daily lives, more people are suffering from eye strain. To prevent or reduce eye strain, try these 3 simple eye exercises:

The 20-20-20 rule

  • Every 20 minutes, look away from your computer for 20 seconds
  • Gaze at an object that is at least 20 feet away
  • Repeat throughout the day

This quick and easy exercise reduces eye strain by resting the eyes and upper body.

Palming

  • Sit in a darkened room with your elbows leaning on a table
  • Relax your back and shoulders
  • Rub your hands together to warm them
  • Place your palms over your eyes — do not press the eye sockets so that your eyes can blink freely
  • Visualize total darkness and breathe deeply for 2 minutes

This exercise relieves stress on the eyes.

Blinking

When we look at a computer screen, we tend to forget to blink. This exercise reduces eye strain and dry eye symptoms.

  • Slowly close your eyes for a few seconds
  • Open your eyes slowly and relax your facial muscles
  • Keep your eyes open for 3-5 seconds
  • Repeat 10-20 times, until your eyes and the muscles around your eyes feel relaxed

While eye strain isn’t a medical emergency, it can negatively affect your quality of life and ability to work and learn. For a definitive diagnosis and treatment plan, schedule a comprehensive eye exam with an eye doctor near you. At York Mills Eye Care, we care about your eyes and health. Contact us today!

  • I can see well. Why do I need to visit an Eye Care Professional?

    Comprehensive eye exams are the best way to prevent “silent” eye diseases like diabetes, glaucoma, and other manageable conditions in their early stages when they are more easily treated. Many conditions can be avoided through planned eye exams.

  • Should my child’s eyes be examined regularly?

    Most Pediatricians test a child’s vision as part of a routine medical examination. They can refer a child to an ophthalmologist if there are signs of an eye condition. Examinations should be done at three years and then regular pediatric eye exams annually.

  • Can my child wear contact lenses and play sports?

    Yes, contact lenses provide excellent vision correction for most sports. However, they can not protect the eyes from injury. Therefore, contact lens wearers should use prescribed sports safety goggles.

  • What is Dry eye?

    Comprehensive eye exams are the best way to prevent “silent” eye diseases like diabetes, glaucoma, and other manageable conditions in their early stages when they are more easily treated. Many conditions can be avoided through planned eye exams.
