Summary
Understanding how specially designed spectacle lenses can help slow myopia progression in children.
Specialty Glasses for Myopia Control
For children who aren't ready for contact lenses, specialty spectacle lenses offer an effective alternative for myopia management.
How They Work
Unlike regular glasses that only correct vision, myopia control glasses create peripheral defocus that may signal the eye to slow its growth.
Types of Myopia Control Glasses
DIMS (Defocus Incorporated Multiple Segments)
- Developed by Hong Kong Polytechnic University
- Honeycomb pattern of defocus segments
- Studies show ~60% reduction in progression
- Available as MiyoSmart lenses
HAL (Highly Aspherical Lenslets)
- Uses aspherical lenslets for defocus
- Available as Stellest lenses
- Studies show ~67% reduction in progression
DOT (Diffusion Optics Technology)
- Uses light-scattering technology
- Available as SightGlass Vision lenses
- Studies show ~74% reduction in progression
Advantages of Glasses
- No touching the eye
- Easy for young children
- No hygiene concerns
- Full-time wear possible
- Can be combined with other treatments
Considerations
- Must be worn consistently
- May take time to adapt
- Higher cost than regular glasses
- Need proper fitting and centration
- Replace as prescription changes
Who Are Good Candidates?
- Children too young for contacts
- Those uncomfortable with contact lenses
- Children with dry eyes
- Anyone preferring non-invasive options
