Myopia Control Lenses Calgary: What are the options for slowing down nearsightedness in children?

As an optical professional with years in the lab, I've seen a significant increase in the number of children being diagnosed with myopia (nearsightedness). It’s a concern for parents, and rightly so. Myopia isn't just about needing glasses; higher levels of myopia increase the risk of serious eye conditions later in life. The good news is that we’re no longer just correcting myopia, we’re actively working to manage its progression. Here's a breakdown of the current options available, specifically with a view toward what makes a difference and what to realistically expect.

What actually causes myopia progression?

Before diving into solutions, it’s important to understand why myopia progresses. It’s a complex interaction of genetics and environment. Essentially, the eye grows too long from front to back. This elongation causes light to focus in front of the retina, resulting in blurred distance vision. While you can’t change genetics, we can influence the environmental factors that contribute to this growth. Increased near work (screens, reading) and reduced time outdoors are strongly linked to myopia progression. Myopia control technologies aim to address the way light focuses in the eye, reducing the stimulus for further elongation. It's not a cure, but a method to slow the rate of progression – think of it as managing a chronic condition.

What are the different types of myopia control lenses?

There are several technologies currently used to manage myopia. Each has its pros and cons, and the best choice depends on the child’s age, prescription, lifestyle, and your budget.

1. MiSight 1 day contact lenses: These are currently considered the "gold standard" by many professionals. They’re daily disposable soft contact lenses with a unique design that creates a peripheral myopic defocus. What does that mean? The lens corrects central vision while creating a slightly blurred image in the periphery. This blurred peripheral image signals the eye to slow down growth. Age range: Typically 8-15 years old, but suitability is assessed on a case-by-case basis. Effectiveness: Research suggests MiSight can slow myopia progression by an average of 50% over three years. Considerations: Requires diligent hygiene and proper application/removal. Not suitable for all children, particularly those who are unwilling or unable to handle contact lenses.
2. Perifocal Spectacle Lenses (like those featuring HALT technology): These lenses incorporate special lens designs to create peripheral defocus similar to the MiSight contacts, but in a spectacle lens format. They’re a good option for children who aren't candidates for contact lenses, or for parents who prefer the convenience of glasses. Age range: 6 years and older. Effectiveness: Studies have shown around a 30-40% reduction in myopia progression, though results can vary. Considerations: Lens thickness can be an issue with higher prescriptions. The design can sometimes cause slight distortion in peripheral vision, which most adapt to quickly.
3. Dual Focus Spectacle Lenses: These lenses have a central distance correction and a surrounding concentric ring of myopic correction. This creates peripheral myopic defocus. They are generally more affordable than MiSight or dedicated perifocal designs. Age range: 6 years and older. Effectiveness: While they offer some benefit, the amount of myopia control is generally less than MiSight or dedicated designs – typically around 20-30%. Considerations: These lenses can sometimes cause noticeable peripheral distortion.
4. Traditional Bifocals and Progressive Lenses: While not designed for myopia control, some research suggests they can offer a slight slowing of progression. This is thought to be due to the reduced accommodative effort required for near work. Age range: Any age. Effectiveness: Limited; often less than 10% reduction in progression. Considerations: Not a primary myopia control solution.

What does the fitting process look like?

A proper fitting is crucial for success. This isn’t just about getting the right prescription. Here’s what you can expect:

1. Comprehensive Eye Exam: A thorough eye exam by an optometrist is the first step. This includes measuring refraction (prescription), axial length (the length of the eye, a key indicator of myopia progression), and assessing overall eye health.
2. Lifestyle Assessment: Understanding the child’s near work habits (screen time, reading distance, duration) and outdoor time is essential.
3. Lens Selection: Based on the exam results and lifestyle assessment, the optometrist will recommend the most appropriate myopia control lens.
4. Fitting and Monitoring: For MiSight, this involves contact lens insertion/removal training, evaluation of lens fit, and ongoing monitoring of vision and eye health. For spectacle lenses, precise measurements are taken to ensure the lens is properly aligned with the eyes.
5. Regular Follow-Ups: Follow-up appointments (typically every 6-12 months) are essential to monitor myopia progression, assess lens performance, and make any necessary adjustments. We’ll re-measure axial length to track changes.

What can I expect in terms of cost?

The cost varies significantly depending on the chosen technology.

• MiSight 1 day: These are the most expensive option, typically around $1200-$1800 per year (including lenses and follow-up care).
• Perifocal Spectacle Lenses: Cost varies greatly depending on the prescription and lens material, but generally range from $500-$1200.
• Dual Focus Spectacle Lenses: More affordable, typically $300-$700.
• Traditional Bifocals/Progressives: Similar in cost to standard spectacle lenses.

Keep in mind that some provincial health plans may offer partial coverage for myopia control lenses. It’s always best to check with your insurance provider.

What’s the realistic expectation?

It's vital to have realistic expectations. Myopia control is about slowing progression, not stopping it entirely. A 50% reduction in progression doesn't mean the child won't need glasses at all. It means that, over time, their prescription is likely to be lower than it would have been without intervention. Early intervention (starting treatment as soon as myopia is diagnosed) is typically more effective. Consistent wear of the lenses is also key. A child who wears MiSight contacts only a few times a week won’t see the same results as one who wears them daily.

Beyond Lenses: Lifestyle Factors

Remember, lenses are just one part of the equation. Encourage your child to spend at least 90-120 minutes outdoors each day. Promote good reading habits: hold books at a comfortable distance, take frequent breaks, and ensure adequate lighting. Limit prolonged screen time.

Making informed decisions about your child’s vision is one of the best investments you can make. By understanding the available options and working closely with an eye care professional, you can help slow myopia progression and protect their vision for years to come.
