Controlling Nearsightedness in Children

Myopia (nearsightedness) is a common vision problem affecting children who can see well up close, while distant objects are blurred. Nearsighted children tend to squint to see distant objects such as the board at school. They also tend to sit closer to the television to see it more clearly.

Sometimes, childhood myopia can worsen year after year. This change can be disconcerting to both children and their parents, prompting the question: "Will it ever stop? Or, someday will this get so bad that glasses won't help?"

Myopia that develops in childhood nearly always stabilizes by age 20. But by then, some kids have become very nearsighted. Here are three possible ways to slow down the progression of myopia in children:

Gas permeable contact lenses

Wearing rigid gas permeable contact lenses (also referred to as "RGP" or "GP" lenses) may slow the progression of nearsightedness in children. It's been proposed that the massaging action of the rigid GP lens on the eye during blinking may keep the eye from lengthening, thereby reducing the tendency for advancing nearsightedness.

In 2001 to 2004, the National Eye Institute (NEI) conducted a controlled study to determine whether wearing GP lenses is effective in slowing the progression of myopia in children. The 116 participants in the study were 8 to 11 years old when the research began.

At the end of the three-year study period, the children who wore GP lenses had only 0.63 diopter (D) less nearsightedness than the kids in the control group who wore soft contact lenses.

The study also found that wearing GP lenses does not slow the growth of the eye, which causes most of the myopia in children. The reduced progression of myopia among those children wearing GP lenses was due only to the effect the lenses had on the front surface of the eye (the cornea). Children who wore the GP lenses had less increase in corneal curvature than those who wore soft contact lenses. The NEI researchers believe these GP lens-induced changes in corneal curvature are not likely to be permanent, and therefore the effect of GP lenses on controlling myopia progression may not be permanent.

Orthokeratology

Orthokeratology, or "ortho-k," is the use of specially-designed gas permeable contact lenses to flatten the shape of the cornea and thereby reduce or correct mild to moderate amounts of nearsightedness. The lenses are worn during sleep and removed in the morning. Though temporary eyeglasses may be required during the early stages of ortho-k, many people with low to moderate amounts of myopia can see well without glasses or contact lenses during the day after wearing the corneal reshaping lenses at night.

Recent research suggests ortho-k may also reduce the lengthening of the eye itself, indicating that wearing ortho-k lenses during childhood may actually cause a permanent reduction in myopia, even if the lenses are discontinued in adulthood.

Bifocals

Some evidence suggests wearing eyeglasses with bifocal or progressive multifocal lenses may slow the progression of nearsightedness in some children. The mechanism here appears to be that the added magnifying power in these lenses reduces focusing fatigue during reading and other close work, a problem that may contribute to increasing myopia.

A five-year study published in the February 2007 issue of Investigative Ophthalmology & Visual Science produced an interesting result involving nearsighted children whose mother and father were also nearsighted. These children, who wore eyeglasses with progressive multifocal lenses during the course of the study, had less progression of their myopia than similar children who wore eyeglasses with regular, single vision lenses.

Dear Valued Patients,

We would like to clarify to our patients that despite the province-wide lockdown starting Thursday, December 24, our office is still open.  Patients who have appointments already booked will still be seen as scheduled.

We will continue to operate in a way that is in alignment with provincial guidelines and is designed to keep you and our staff safe while still allowing us to deliver the high standard of eye care you are accustom to.

Our doctors have modified their schedules to increase physical distancing. As a result, fewer appointments are available, and we are having to assign these appointments to people with immediate and greatest needs.

We will also be:

• Using telehealth appointments, when appropriate, to deliver care from a distance.

• Time in our Frame Gallery will be scheduled for patients to try on and choose eyewear.

• All eyewear adjustments, repairs, and pick-ups will be scheduled.

• Our doors will be closed as we will not be accepting walk-ins at this time.

• Contact lenses will continue to be shipped directly to patients.

We look forward to servicing our amazing community with all their eye care needs and thank you for supporting us as we navigate these unprecedented times.
