Myopia may seem to be an distance vision problem, making eyewear a new necessity— but in reality, myopia can be far more detrimental to your child’s vision.
Myopia is caused by the light entering the eye and focusing in front of, rather than directly, on the retina. The increase in myopia is caused by the shape of the eye, which causes the length (axial length) of the eye to grow.
Regular single-vision glasses and contact lenses have been shown to possibly contribute to myopia progression.
Distance-only glasses and contact lenses focus light in a way that can actually increase the axial length of the eye— ultimately causing myopia to worsen.
A child with myopia has an increased risk for developing vision threatening eye diseases later in life, such as:
- Retinal detachment
- Myopic macular degeneration
Is there a way to prevent my child’s myopia from worsening?
A number of recent studies suggest that it may be possible to control myopia by totally stopping, or at least slowing down, its progression during childhood and teenage years.
Myopia management is a treatment program to keep the level of myopia as low as possible, and to reduce your child’s risk of developing eye disease.
Myopia Management has shown to decrease myopia progression by up to 78 percent.
Myopia management can involve the use of eyeglasses, contact lenses, and eye drops— all scientifically proven to aid in the control of myopia progression.
A closer look at myopia management
Eyeglasses are a popular choice for children with myopia as they enable vision acuity for distant images. Many times, reduced focusing skills can contribute to the development of myopia— these children may need a bifocal or multifocal lens to support the child’s focusing skills.
Bifocal and multifocal lenses contain different lens powers throughout the lens, and enable clear vision at all distances. The specific power for the child’s near vision reduces stress on the eyes and possibly the progression of myopia.
Contact lenses provide clear vision at all distances, with a wider field of view as compared to eyeglasses. A multifocal contact lens works similar to eyeglasses to improve distance vision acuity while simultaneously reducing the stress on the eyes for reading and other near vision tasks. This can consequently reduce myopia progression.
Atropine eye drops
These medicated eye drops can be used to dilate the eye’s pupils during an eye exam, but have also been proven to reduce myopia progression. A very low dose of this eye drop is placed in the child’s lower eyelid every day.
This method is effective for children between the ages of 8 and 15, it only requires a single drop into the child’s eye once per day. Side effects may include blurry near vision or light sensitivity. Children will still need to wear their regular glasses or contacts during the day, but the eye drops can assist in slowing down the worsening myopia.
Orthokeratology (Ortho-k)/ Corneal Refractive Therapy (CRT)
Ortho-k reduces myopia progression through the use of specialized rigid contact lenses that reshape the cornea, the front outer surface of the eye. The contacts work to flatten the cornea, thereby changing the way light is focused on the retina at the back of the eye.
The contact lenses are inserted before bedtime, and are generally only worn while your child sleeps. Ortho-k provides clear vision for the whole day, thereby eliminating the need for wearing glasses or contacts during the day.
Ortho-k has been proven to reduce the rate of myopia progression in children by up to 50 percent.
Can vision therapy control myopia progression?
Vision therapy is an appropriate and effective treatment for children who have acquired myopia as a result of reduced eye focusing skills. Vision therapy involves a personalized program that trains the child’s visual system, including the eye-brain connection, to work more efficiently— thereby improving focusing abilities. Children who have reduced focusing skills, have a greater risk of developing progressive myopia.
When should my child start myopia management?
It is best to begin Myopia Management as soon as possible to increase optimal results. Myopia generally worsens through the teenage years, and stabilizes as the child reaches adulthood, so these years are the optimum time to seek Myopia Management options for your child.
There are now excellent management options to help your child— an eye doctor with experience in myopia management will be able advise which treatment option is most effective for your child.
