Myopia is a condition when the eye is longer than it should be, and the optical components of the eye bring light to a focus in front of the retina. Myopia causes blurred vision but can be corrected with glasses or contact lenses. In children myopia is often progressive, caused by excessive elongation of the eyeball. Myopia progression causes a child’s vision to decline and is associated with a higher risk of eye diseases including retinal detachment, maculopathy, cataract, and glaucoma, increasing in risk with higher amounts of myopia; in addition, both children and adults feel worse about their personal appearance when they have high myopia.
|Odds Ratio Risk of Eye Disease||
|Refractive error||Retinal Detachment||Maculopathy||Cataract||Glaucoma|
|-1.00 to -3.00||3.1x||2.2x||2.1x||2.3x|
|-3.25 to -6.00||9.0x||9.7x||3.1x||2.5x|
|-6.25 to -9.00||21.5x||126.8x||5.5x|

At North Peace Optometry Clinic our doctors are knowledgeable in many ways to slow myopia. The remainder of this page will outline various methods of myopia control, starting with the most effective methods.
Hoya MiYOSMART ophthalmic lenses
This is the newest and most proven ophthalmic lens design for myopia control in children. The MiYOSMART lenses incorporate patented technology called Defocus Incorporated Multiple Segments that slow the growth of the eye. When compared to conventional lenses, the MiYOSMART lenses slow myopia progression by 59%. Your child will enjoy clear vision with these spectacle lenses.
- Easiest treatment for children that are accustomed to wearing glasses
- No bifocal lines. No cosmetic difference from normal glasses.
- 100% UV protection
- Newest treatment available.
- Our doctors are trained and certified to offer this unique form of treatment
CooperVision MiSight soft contact lenses
The world’s first one-day soft contact lens approved to slow myopia in children. Clinically proven to slow myopia progression by 59% and axial length by 52%, while safe in children as young as 8 years of age. Simple and easy to use – after just 1 month of wear 85% of children said the contact lenses were easy to insert.
- Effective at myopia control
- Allows freedom from glasses. 100% of children preferred MiSight lenses over glasses
- Safe in children as young as 8 years of age
- Easy for children to insert and remove
- Only available at clinics with doctors that are certified to dispense MiSight lenses
A custom fit rigid contact lens, worn overnight to reshape the surface of the eye. These lenses are safe, well studied, and have been used in myopia control for decades. They also eliminate the need for glasses or contact lenses to be worn during the day. They have been proven to be safe in children as young as 8 years of age and slow elongation of the eye by 43%.
- Third most effective form of myopia control
- Safely reshapes the front surface of the eye overnight
- Eliminates the need for glasses or contact lenses during the daytime
- Safe in children as young as 8 years of age
Atropine Eye Drops
Eye drops taken at bed time to slow myopia growth. These drops are well tolerated with low risk of side effects. Studies show that the drops slow myopia progression by 43% and axial length by 29%. The drops should be instilled every night. Studies found that the eye grows faster for a short period when children stop using the drops; therefore our doctors stress that atropine drops need to be a long-term therapy in order to be effective. In rare instances, children may need bifocals or lenses that darken outside.
- Eye drops instilled at bed time
- Safe in children as young as age 4
- Children should continue to wear their glasses
- Effective only when implemented as a long term therapy
All methods of treatment require close follow up to monitor eye health, clarity of vision, and myopia change. There is no therapy that completely stops all myopia progression and parents should be aware that results may vary. Our doctors are happy to help improve your child’s sight and reduce their risk for future eye health problems.
