Why Are Dilated Eye Exams So Important?

InVision Eyecare Dilated Eye Exam near you in Lethbridge, Alberta

Having your eyes dilated during an eye exam may seem like a nuisance. But when you consider the benefits of a dilated eye exam, the temporary blurred vision and sensitivity to light that typically follow are definitely worth it.

What Are Dilated Eye Exams?

At some point during a comprehensive eye exam, your optometrist will shine a bright light into your eyes to examine the back of your eye, called the retina. The problem is that bright light causes the size of the pupil’s opening to shrink, which makes it hard for the optometrist to see a large portion of the retina.

That’s why eye doctors apply special eye drops in each eye to keep the pupils open. A dilated pupil allows for a much more accurate assessment of your eye’s structures, including the focusing lens, blood vessels and tissues at the back of the eye called the retina, as well as the optic nerve and macula.

Dilating the eyes makes it easier for your optometrist to detect the following conditions and diseases:

It’s important to note that many of these conditions can develop without noticeable symptoms, until they cause vision loss at which point treatment may be more challenging, making dilated eye exams all the more crucial.

The Dilation Process

First, your eye doctor will apply eye drops to each eye to trigger dilation of the pupil. Your eyes should be fully dilated about 10-20 minutes later.

Your eyes will remain dilated for 4-6 hours, and during this time you may be sensitive to light. That’s because the larger pupil allows more light than usual to enter the eye. Many patients find it more comfortable to wear sunglasses until their eyes return to normal.

Reading and using a computer may be difficult with dilated eyes, and your vision may be blurred. Some patients report feeling a tightening sensation in their eyelids, or headaches.

At what age should one have a dilated eye exam?

You should have your dilated eye exam no matter your age. Most eye doctors will dilate a new patient at their first exam regardless of age to get a baseline of their retinal health.

Will I be able to return to work after a dilated eye exam?

Everyone reacts differently, so it’s hard to tell. If your job requires you to focus on small print or detail, it may be challenging. Typing and writing may also be difficult with dilated pupils. To be on the safe side, book your appointment at the end of your work day, clear your schedule after your eye exam and only plan to do activities which aren’t visually demanding.

Are You Susceptible To Vision Loss?

Ask Our Eye Doctor in Lethbridge, Alberta, how To Prevent Vision Loss

Vision loss is more common than you may think! In fact, it’s among the most prevalent disabilities in adults and children. Knowing what puts you at risk of developing vision loss is important and can help you to be proactive about caring for your eyes.

Below, we’ll explore the most common causes of vision loss and the risk factors associated with each.

Spreading awareness and education about visual health is just one way that our eye doctors near you can help. To schedule your Comprehensive eye exam, call us today 403-329-0200.

Glaucoma

Glaucoma is a group of eye diseases caused by a buildup of pressure within the eye. Too much inner-eye pressure can damage the optic nerve and lead to vision loss.

Since symptoms don’t usually manifest in the early stages of glaucoma, getting regular eye exams is all the more crucial. Advanced or rapidly progressing glaucoma can show a variety of symptoms, such as blurred vision, headache, severe eye pain and redness, seeing halos around lights, and nausea.

Risk factors for developing glaucoma include:

  • Being 60 years or older
  • Family history of glaucoma
  • African, Asian, or Hispanic descent
  • High myopia (nearsightedness) or hyperopia (farsightedness)
  • Previous eye injury or certain eye surgeries
  • Certain medications, like corticosteroids
  • Thin corneas
  • Certain medical conditions, like diabetes, hypertension, heart disease, and sickle-cell anemia

Cataracts

Cataracts occur when the eye’s lens becomes cloudy. A healthy lens is clear and allows light to pass through it undisturbed.

Common cataract symptoms include cloudy or blurred vision, difficulty seeing at night, light sensitivity, double vision in the affected eye, and seeing colors as faded or yellowish.

Risk factors for developing cataracts include:

  • Aging
  • Diabetes
  • Hypertension
  • Smoking
  • Previous eye surgery, injury, or inflammation
  • Alcoholism
  • Extended use of corticosteroids

Age-Related Macular Degeneration (AMD)

AMD is the leading cause of severe vision loss in adults over the age of 60. It occurs when the macula (the small central portion of the retina, which is responsible for sharp, colorful, central vision) begins to wear down.

Early stages of AMD usually go unnoticed, but later stages of the disease can produce symptoms like blurred vision, dark or blurry areas in your central vision, and problems with color perception.

There’s not yet a cure for AMD, but certain treatments can help prevent vision loss.

Risk factors for developing AMD include:

  • Smoking
  • Obesity
  • Aging
  • Long-term sun exposure
  • Hypertension
  • Heart disease
  • Family history of AMD
  • Light-colored eyes
  • Farsightedness

Diabetic Retinopathy

Diabetic retinopathy (DR) is a complication of Type 1 or 2 diabetes that affects the light-sensitive tissue at the back of the eye called the retina.

Initially, diabetic retinopathy shows no symptoms but can eventually lead to blindness. As it develops, it can cause increased floaters, impaired color vision, dark spots in your visual field, and blurred vision.

Risk factors for developing diabetic retinopathy include:

  • Length of time from diabetes diagnosis — the longer you’ve had it, the higher your chances of developing visual complications
  • Uncontrolled blood sugar
  • Obesity
  • High cholesterol or blood pressure
  • Pregnancy
  • Smoking
  • African American, Hispanic, and Native American ethnicities
  • Family history of DR

So, what’s the bottom line?

Multiple factors contribute to eye disease and vision loss, and some may even be relevant to you. If you think you may be at risk for vision loss or experience any of the symptoms listed above, speak with your eye doctor in Lethbridge as soon as possible. We also recommend you have your eyes thoroughly examined every 1-2 years, or as often as your eye doctor recommends. To schedule your comprehensive eye exam, call InVision Eyecare today.

Can blindness be prevented?

When caught early, many eye diseases can be treated to halt or slow the progression of the disease and potentially prevent vision loss. The best things you can do to preserve your vision for the long term is to lead a healthy lifestyle and make sure you undergo a comprehensive eye exam every 1-2 years.

Which eye diseases are genetically inherited?

More than 350 ocular diseases have some sort of genetic component. Certain diseases, like retinitis pigmentosa and albinism, are directly inherited through chromosomal information. In other cases, a predisposition to the disease is inherited, rather than the disease itself.
