Why Are Dilated Eye Exams So Important?

Armstrong & Small Eyecare Centre Dilated Eye Exam near you in Winnipeg, Manitoba

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:

Cataracts
Glaucoma
Diabetic retinopathy
Macular degeneration
Retinal tumor
Retinal detachment or retinal tears
Eye floaters

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.

Why Does Bono Always Wear His Signature Shades?

Ask our optometrist in Winnipeg, how Do Sunglasses Help People With Glaucoma?

Ever wonder why rock superstar Bono wears sunglasses, even when indoors? It’s not due to his “look”, but rather is related to managing his glaucoma.

Ever wonder why Bono always wears shades, even when indoors? U2’s frontman doesn’t wear sunglasses simply as part of his image. Bono has had glaucoma, a build-up of pressure in the eyeball, which can damage the optic nerve and potentially lead to blindness if untreated—for over two decades now.

The real reason he wears his trademark shades is due to this progressive, sight-robbing eye disease, to protect his sensitive eyes from light and glare.

How Do Sunglasses Help People With Glaucoma?

People with glaucoma experience sensitivity to light (or photophobia) and glare, among other symptoms. When the sun is strong, those with this condition will be more affected by glare emanating from a variety of surfaces, like water, snow, sand or pavement, than the average person. Furthermore, certain glaucoma medications constrict the pupils, which can further contribute to acute sensitivity to glare and light, as well as redness and irritation.

That’s why people with glaucoma — and lots of people without glaucoma — feel best wearing sunglasses when outdoors on a sunny day, in a bright indoor space, or while driving in the early evening.

Here’s How You Can Protect Your Eyes

By wearing sunglasses that offer 100% UV protection, you can reduce your risk of developing sight robbing diseases, like cataracts and macular degeneration, and reduce glaucoma symptoms. Polarized lenses, in particular, can help with glare. With yearly comprehensive eye exams, early diagnosis and consistent treatment, you can prevent vision deterioration from glaucoma or similar sight-threatening eye diseases.

Can glaucoma be cured?

While there is currently no cure for glaucoma, there are many effective treatment options available. Treatments that can help stop or slow the progression of glaucoma include eye drops, oral medications, as well as laser and surgical procedures.

How can glaucoma vision loss be prevented?

The best way to avoid glaucoma-related eyesight deterioration is to undergo regular eye exams, as glaucoma can be detected and treated even in its early stages, which can prevent significant vision loss or blindness. That’s why routine eye exams that include glaucoma testing are so important.

See Under the Sea & in the Swimming Pool Too

Wear goggles for clear & healthy underwater vision

You don’t swim naked at a public beach or swimming pool, and you shouldn’t swim with naked eyes either! At the beach, it’s hard to know if ocean water is really clean and not polluted, and the sand and salt content can make your eyes sting. If you prefer swimming in a pool, remember that while pool water can be clean, that’s only because it’s packed with chlorine, which can seriously irritate your eyes, stripping away your lubricating film and causing redness, pain, and blurry vision.

Goggles are the ideal solution for protecting your delicate eyes against the harshness of water. Also, due to advanced materials and modern engineering of the lenses in swim goggles, they provide crisper underwater vision than ever before! Your knowledgeable Winnipeg eye doctor explains about the benefits and features of goggles:

Prescription goggles

If you normally need eyeglasses or contacts to see above water, our Winnipeg optometrist strongly recommends buying a pair of prescription goggles for underwater vision. For you to see, light rays reflect off an object, enter your eyes, and are focused on your retina clearly. However, light rays don’t function the same way when they are in water. That’s why the floor of a swimming pool appears higher up than it really is. In general, goggles correct this problem by creating an air-filled gap around your eyes. But this doesn’t give sharp sight to swimmers who need vision correction. If you have nearsightedness, farsightedness, or astigmatism, you’ll need prescription goggles to see.

Wearing contact lenses and standard goggles

A lot of people are in the habit of wearing standard goggles over their contact lenses, instead of purchasing a pair of prescription goggles. What’s the problem with this? Actually, water is the problem.

Water in all bodies – lakes, pools, oceans, and hot tubs – is a natural breeding ground for bacteria and microorganisms. While your body and your eyes have a built-in defense system to protect against these menacing microbes, contact lenses interfere with your eye’s protection. Consequently, swimming with contact lenses increases your risk of getting an eye infection.

Acanthamoeba keratitis is an extremely hazardous eye infection caused by amoeba being trapped between your contact lens and your cornea. Sometimes, amoeba start to live in your eye, leading to corneal ulcers and permanent vision loss. This type of infection only happens to people who wear contact lenses, which underscores our Winnipeg eye doctor’s warning against swimming with contacts!

Now, we also realize that many people will insist on wearing contact lenses at the beach or pool – despite all of our warnings. If you’re one of those people, here are some tips to help you minimize the danger to your eye health:

Wear daily disposable contacts for swimming, since you throw them out after a single use. Remove them immediately after you come out of the water, rinse your eyes with artificial tears and replace your lenses with a new, clean pair.
Even if you’re didn’t fully dip into the water, if any drops fall into your eyes, remove your contacts immediately and throw them out, or disinfect them if you aren’t wearing disposables.
Never open your eyes underwater
Never go swimming and then doze off on the shore or poolside with your lenses still in your eyes
