Myopia can affect your child’s vision and worsen with time, placing their eye health at risk. However, your eye doctor can help correct your child’s vision and slow myopia progression with specialized treatments. If your child has myopia, what lenses can help control this condition? 

Continue reading to learn about myopia, including what treatments are available and what lenses can help slow myopic progression. 

What Is Myopia? 

Approximately 30% of Canadians have myopia, a common refractive error. If you have myopia, nearby objects appear clearly while faraway images look blurry. Many people develop this condition when they’re children. 

While myopia can develop early in childhood, your child may not know they have a vision problem. They may assume everyone sees as they do, making it important to watch for signs of an eye problem in your child. 

Your child may have myopia if they experience any of the following symptoms

  • Trouble seeing the front of the classroom clearly
  • Partially closing their eyelids or squinting to see clearly
  • Headaches caused by eyestrain 
  • Frequent eye rubbing & excessive blinking
  • A desire to sit close to the television or at the front of the classroom to see

What Causes Myopia?

Someone with myopia has unique eyes where their cornea is too steep or their eyes are too long. Their eye shape causes light to focus in front of the retina instead of on the retina as it should, leading to blurry vision.

Besides eye shape, other factors can affect myopia development, including: 

What Is Myopia Progression? 

Your child’s eyes continue to grow as they do, meaning that myopia can progress as they age. When myopia is left untreated, it can gradually worsen until it becomes a more severe form, known as high myopia

Someone has high myopia when they need -5.00 dioptres or more of vision correction. For most people, myopia tends to stabilize in early adulthood. There’s a chance that myopia progresses for years if left untreated, causing your child to need heavy prescriptions to see clearly later in life. 

Besides blurry vision, high myopia increases the risk of developing several eye conditions, including: 

How Do Optometrists Treat Myopia?

Your eye doctor can address myopia progression with specialized treatments. Depending on your child’s unique vision situation, these treatments can include contact lenses, glasses, eye drops, or vision therapy. Glasses and contacts can be a good treatment option because they help slow myopia progression while helping your child see more clearly. 

What Lenses Are Available to Control Myopia Progression? 

Controlling myopia with lenses can help slow myopia progression in your child’s eyes while providing them with clearer vision at the same time. Your optometrist can recommend the treatment option they think best suits your child’s needs during an eye exam. Whether with contact lenses or glasses, your eye doctor can help slow myopia progression in your child. 

Some myopia control lenses include MiSight and Abiliti contacts, MiyoSmart glasses, orthokeratology, SightGlass, and Stellest. 

MiSight and Abiliti Contact Lenses

MiSight contact lenses and more recently Abiliti contact lenses have a unique design specialized for children with myopia. They’re disposable lenses your child replaces daily, making them easy and safe to use for even younger children. These lenses can help correct and control myopia by creating myopic defocus, a technique to change how the eye focuses light. 

The lens centre helps correct your child’s vision, and contains different types of myopia treatment zones to help focus light in front of the retina instead of behind the retina, shifting your child’s focal point of vision and tricking the eye into not growing. 

Soft daily myopia control contact lenses can help slow myopia progression by up to 59% in children

MiyoSmart Glasses

MiyoSmart glasses can help your child see better while slowing myopic progression. These glasses utilize defocus incorporated multiple segments (DIMS) technology to help images focus in front of the retina instead of behind the retina, known as myopic defocus. 

A MiyoSmart lens features a central zone for correcting myopia. Additionally, it has several ring-shaped zones surrounding the lens to slow myopia progression. 2019 research found that the DIMS technology used in MiyoSmart lenses can help slow myopia progression by up to 60% in children over 2 years. 

Orthokeratology (Ortho-K)

Orthokeratology, also known as ortho-k, is a corneal reshaping lens. These durable and rigid contact lenses help control and correct myopia. They gently reshape the cornea overnight, allowing your child to see clearly throughout the day without needing corrective eyewear. 

Ortho-k contact lenses flatten the centre of the cornea to change how light bends as it enters the eye, correcting your child’s vision. These lenses are safe and effective—2018 research discovered these contacts can slow myopia progression by 36–56% in children

SightGlass

SightGlass is a new way to help control and correct myopia in children. These eyeglasses feature thousands of micro-dots in the lens, helping scatter light and reduce contrast on the retina. 2020 research found these glasses slowed myopia progression in 85% of the children in the study, with myopia progressing less than a dioptre. 

Stellest Lenses

Stellest lenses feature HALT technology to help correct and control your child’s myopia. These lenses have tons of tiny lenses (known as lenslets), which help slow down myopia progression. When worn 12 hours a day, Stellest lenses can slow myopia by up to 67%

You Can Help Protect & Preserve Your Child’s Vision

Myopia can affect your child’s vision and eye health more than you think. Besides needing heavier prescriptions in adulthood, myopia can increase your child’s risk of eye disease if it worsens. However, early action can help slow myopia progression and protect your child’s vision. Contact your eye doctor if your child has myopia symptoms.
