About 3/4 of Canadians require some type of vision correction. These days poor vision is usually corrected after a trip to the eye doctor and a new eyeglass prescription; however, eyeglasses have not always been available. Trace the history of eyewear – from reading stones to lightweight lenses and plastic frames that we enjoy today. Continue Reading
Your eyes could have a lot to do with the headaches you’re experiencing. Whether they result from eye strain, vision problems or even eye disease, these headaches are unpleasant and can seriously affect your lifestyle and comfort. Continue Reading
A natural part of the aging process is presbyopia — farsightedness resulting from a loss of elasticity in the eye lens. Eventually, eye muscles tire out and cannot expand and contract as easily as they used to. The result: the inability to clearly focus on close objects. Things like reading menus, pill bottles or books becomes increasingly difficult. Continue Reading
Myokymia is the medical term for that annoying eye twitch, the condition where an eye starts contracting uncontrollably. It’s an irritant like hiccups; not necessarily a cause for alarm, but a perplexing condition that comes and goes without real rhyme or reason. Continue Reading
Laser eye correction is often advertised as a solution for vision problems that is permanent and pain-free, with minimal healing time. While laser eye surgery could be a suitable option for some, there are risks associated with the procedure that are often overlooked.
How Does Laser Eye Correction Work?
Laser eye correction is a surgical procedure that reshapes a person’s cornea to improve vision. First, a laser is used to create a corneal flap to access the underlying corneal tissue. Then, a laser is used to remove tissue, which reshapes the cornea so it can more accurately focus light on the retina. Finally, the flap is repositioned and left to heal.
Risks Associated with Laser Eye Correction
As is the case with all surgical procedures, laser eye surgery carries risks:
Over-Correction/Under-Correction: Sometimes, vision isn’t improved because the surgeon removed too much corneal tissue (over-correction) or not enough tissue (under-correction). After a few months of healing, you may be eligible for a follow-up enhancement surgery to try to correct the vision again.
Deteriorating Vision: Over time, vision may return to pre-surgery levels. Many laser eye correction advertisements make the false claim that patients who undergo the surgery will never need glasses again. Even if the procedure is performed successfully, natural aging will deteriorate vision — requiring eyeglasses to see clearly.
Halos/Double Vision: After the procedure, many patients report having trouble seeing in dim lighting due to contrast sensitivity loss. There have also been reports of seeing halos, starbursts, glares and experiencing double-vision that require a person to wear prescription eyewear to correct the vision to perform regular activities, like driving safely at night.
Dry Eyes: The most common complication of laser eye correction is dry eyes. Nerves responsible for tear production could be severed during the procedure. In some instances, the symptoms of pain, burning and foreign body sensation are permanent.
Laser eye correction is an elective surgery that holds no medical reason to risk serious complications when glasses and contact lenses provide a safe alternative.

20/20 vision is a term you may have heard but not truly understood. During eye exams, many of our customers mistakenly believe that having 20/20 vision equates to “perfect” vision and become worried about their eye health after learning their eyesight is a bit different. Continue Reading
According to estimates from the World Health Organization (WHO) Prevention of Blindness and Deafness Program, about 285 million people worldwide are visually impaired, with about 90% of those people living in developing countries1. Individuals in these countries face many barriers in obtaining access to prescription eyeglasses, but their main obstacles are access to optical locations and affordability of eyeglasses.

According to the Glaucoma Research Society of Canada, glaucoma affects more than 400,000 Canadians and is one of the leading causes of blindness among older Canadians. There is currently no cure – but early detection with an annual, comprehensive eye exam can slow or prevent vision loss.
What Is It?
Glaucoma is associated with increased ocular pressure in the eye, which, if left untreated, can result in impaired vision or total loss of sight. There are several types of glaucoma, but the most prevalent is primary/chronic open-angle glaucoma. In this form of the disease, drainage canals in the eye become clogged over time. This increases pressure in the eye and damages the optic nerve. Blind spots can develop as the optic nerve is progressively damaged. Once the nerve is completely destroyed, it will result in total blindness.
Potential Risk Factors for Glaucoma
Anyone can develop glaucoma, but there are certain risk factors that tend to carry a higher rate of contracting the disease.
- Age – People over the age of 60 have a higher risk of developing glaucoma.
- Health – Those that suffer from diabetes and hypothyroidism have a higher risk factor.
- Previous eye injury or eye surgery – Can contribute to developing glaucoma.
- Family History – If members of your immediate family have the disease, you have a much higher risk of developing glaucoma.
Glaucoma is often called the silent thief of sight because of its slow progression and ability to cause irreparable harm before any symptoms emerge. Many times, people live with glaucoma year after year, symptom-free. Once symptoms finally do appear, it’s too late for treatment plans.
The only way to detect glaucoma is through a regular, comprehensive eye exam. A licensed optician typically performs two specific tests to check for glaucoma:
- Tonometry – Checking the pressure of the inner eye.
- Ophthalmoscopy – Checking the shape and the colour of the optic nerve.
It’s only through these tests that a diagnosis can occur, which is why it’s critical to schedule an annual eye exam to stay on top of any changes in your eyes.
While vision loss caused by glaucoma cannot be reversed, early detection from eye exams allow for treatment options that can slow or halt complete vision loss. Options for decreasing intraocular pressure include: eye-drops, laser treatment and surgery.

In the past two years or so, we’ve seen an increase in online retailers specializing in prescription glasses. These websites boast large selections of frames and apparently easy, step-by-step purchasing at lower costs. However, they fail to warn consumers of the consequences that follow the wearer after buying glasses online.
